What are the white spots on teeth? Get insights on causes of spots on teeth, after braces, whitening, being sick, how to prevent and get rid of such marks effectively.

What Causes White Spot on Teeth?

The white spots on your teeth can be easily identified because they are lighter than the rest of the enamel and might even have a completely different texture from the surrounding tooth.
Such spots on teeth are usually locations where the minerals in tooth enamel have been worn out or removed. The process is known as demineralization or decalcification.
What is left is a hollow structure that is whiter than the rest of the tooth. Some of these areas might actually feel like pitted regions or indentations in the tooth.
The spots are usually permanent although they can fade a small amount over time even if you do not get professional treatment.
Your dentist may tell you that the first evidence of tooth decay is a white spot lesion, meaning your tooth’s enamel will have an opaque color in the spot where the cavity is starting to form.
Decay caused by white spots on teeth requires examination and treatment by a dentist. Since there are several different causes for these white spots, it’s best to have your dentist examine your teeth when you first notice them appearing so he or she can try to determine why you are developing them.

White Spots on Teeth Causes

Here are some of the major reasons for white spots on teeth.

1. Acidic foods and drinks.

White spots on teeth can be caused by consuming too much acidic food or drink. For instance, if you drink a lot of sports drinks, vitamin water, carbonated soda, lemonade, or apple cider vinegar, their high acidic content can rapidly eat away at your teeth’s enamel and natural minerals. Eating sour candies and foods made with lemon or vinegar can also cause these spots as well.

2. Dry mouth.

If you have a dry mouth and not enough saliva to keep your mouth’s pH level near neutral, acid-producing bacteria will thrive and attack your teeth.
Certain prescription drugs, medical conditions, tobacco usage, and breathing through your mouth when sleeping can cause dry mouth.
Drink plenty of water to stay hydrated, suck on xylitol mints, or use mouth rinse specially formulated for dry mouth.
3. Plaque buildup from poor oral hygiene.
Plaque is a sticky, colorless film of bacteria and debris that forms on your teeth after eating carbohydrates (sugars and starches).
The bacteria feed on sugars in your mouth and produces acidic waste that dissolves your enamel, which causes white decalcification, and cavities.
4. Acid reflux.
If you suffer from acid reflux, your mouth will experience higher levels of acidity than normal. This high acidity can damage your teeth, resulting in white spots.

5. Celiac disease.

Celiac disease is an autoimmune disease affecting up to 4% of the population. Celiac disease may cause white spots on teeth. Besides causing the spots, celiac disease can also lead to undersized teeth, yellowing teeth, and teeth with groves or pitting on permanent teeth.

6. Excessive fluoride (fluorosis).

Consuming excessive fluoride, especially during your teeth’s development, can cause teeth to develop white spots. For instance, if you live in an area where drinking water contains a high fluoride level.

7. Genetic disorders. In some cases, the white spots on your teeth may be caused by genetic disorders.
8. Whitening strips. It’s been reported that even some brands of whitening strips can cause white spot on teeth, especially if they are left on for several months. They are highly acidic and over time can de-mineralize the tooth’s enamel.
9. Wearing braces. Braces won’t cause white spots on teeth, but poor dental hygiene while wearing them can cause Plaque builds up on hard to reach places because braces make it hard to brush your teeth well. When the braces are removed, these places could have white spots as well as tooth decay.
10. Decalcification:

Spots on teeth can also be caused by decalcification, which is the loss of calcium salts in the teeth and bones. If your diet lacks calcium, or you have a genetic issue with absorbing calcium, you could be dealing with decalcification.

White spots on teeth child

Most babies don’t start getting teeth until they are 6 months old, infant dental care is important from the very beginning. Many dentists recommend an initial visit before the child’s first birthday to make sure teeth and gums are cared for and cleaned properly.

What may cause White spots on teeth child

1. Decay

When you see white spots on baby teeth, often those spots can be an early sign of tooth decay, but it can also be an indication that your child is getting too much fluoride
White spots on teeth are often one of the first signs of tooth decay in children. The spots often appear along the gumline and are usually a chalky, pale color. If the decay continues, these spots will eventually turn brown or yellow.
At this point, the decay is still reversible. Once you see these spots on your child’s teeth, you should see dentist. He or she will most likely provide a gentle fluoride treatment and clear any plaque and tartar off of the enamel while they’re there. Receiving fluoride early in the process can help reverse the decay by strengthening your child’s tooth enamel and preventing the formation of acid that wears away the teeth over time.

2. Fluorosis

White spots on teeth child can be a sign of too much of fluoride. This is called Fluorosis. In many cases, the white spots that develop on teeth affected by fluorosis are barely visible or only so when a child sees a dentist. The spots that form in this case might be blotchy or streaky.
One thing about fluorosis is that, a child can only develop the condition while his or her teeth are still forming.  Once the permanent teeth come in, the risk for fluorosis drops.
Another advantage concerning fluorosis is that it may actually be helpful because it can make the teeth become resist to decay.
Note
Although fluorosis is usually not harmful to children or their teeth, you should take action to make sure your child is getting just enough fluoride and not too much.
Keep an eye on how much water your child drinks – one of a few major sources of fluoride in his or her daily routine. At this age, your child specifically doesn’t need to use fluoride mouth rinses or tablets, unless the dentist recommends it to treat a separate issue.
It’s a good idea to keep an eye on your child when brushing his or her teeth, as it’s possible to go overboard with toothpaste as well.
When it’s time to brush, put just a pea-sized amount of toothpaste on your child’s brush and explain that the amount is just right for getting their teeth clean. Additionally, remind your child not to swallow the toothpaste; always spit it out when you’re done. You might want to practice brushing together so your child can clearly see the right way to brush their teeth.
Not only will this help your child enjoy a healthy mouth from a young age, but it will help him or her learn excellent oral care habits that last a lifetime.

White Spots on Teeth after Brace

Dental braces (also known as braces, orthodontic cases, or cases) are devices used in orthodontics that align and straighten teeth and help to position them with regard to a person’s bite, while also working to improve dental health
Braces can do amazing things for people with overbites, under-bites or crooked teeth. They do have to be worn for a significant amount of time to straighten the teeth. This can sometimes cause problems. White spots on teeth can eventually be realized after the removal of braces. The spots are normally around or just under where the braces were mounted. This can affect the appearance of your smile for decades to come.
If you do not do anything, then the white spots are likely to remain visible on your teeth permanently. Fortunately, many different treatments exist today that can either minimize or eliminate the appearance of the spots.
Below are some of the most common ways to get rid of the white spots on your teeth once the braces are removed.

1. Good Oral Hygiene

When you want to relieve the problem of white spots on teeth after brace is by practicing good oral hygiene. This means brushing two to three times a day and flossing daily.
This benefits your teeth in two ways. The first is that the action of brushing is going to help normalize the appearance of your teeth so that the bright white spots start to fade.
The second way is by removing any bacteria that could easily get into the demineralized areas and cause more damage or staining. Flossing is important because it gets more of the bacteria out of your teeth.

2. Dental Veneers

This is a common dental procedure that can effectively remove any signs of the white spots on your teeth that appear after removing braces.
These are slivers of a material like porcelain or a composite resin. Your teeth are treated to make the surface rough. The veneer is then affixed to the front and secured in place with a type of dental cement.
The veneer has a completely natural appearance. It creates a new surface and hides the marks beneath. Dental veneers are a fast and easy way to regain a bright and healthy smile.

3. Re-Mineralization

One of the most common ways to remove white spots on teeth after braces is through a process known as re-mineralization. This technique is effective because it directly addresses the problem causing the spots in the first place.
Re-mineralization involves applying some type of cream or other substance to your teeth for a set period of time. The cream contains the minerals that the bacteria have removed from your teeth. Your teeth will reabsorb those minerals rebuilding the area. Re-mineralization can cause the spots to fade or could remove them completely depending on your individual situation.

4. Composite Restoration

The white spots on your teeth sometimes sink below the surface of the surrounding enamel creating a sunken area. If this happens, then composite restoration is a way to deal with the problem.
Composite restoration is a dental procedure that uses a special type of resin. The resin is applied to your teeth over the white spots. It basically fills in the area so that it is level with the rest of the enamel. The resin can be colored to match the rest of the tooth. Composite restoration has the potential to solve any problems you have with discolored areas after your braces are removed.

5. Tooth Whitening

This is very common procedure that could help is tooth whitening. This special chemical process uses hydrogen peroxide solutions or other substances to make your teeth whiter. It can have a fast and direct impact on the white spots on teeth after braces.
The whitening solution will help to normalize the color of your teeth making the untouched enamel brighter. The result will be teeth that look much more natural. You can do tooth whitening at home with a kit or see a dentist for treatment. The type of professional whitening done by a dentist is far more effective in this situation.

6. Microabrasion

Another way to get rid of the white spots is through a process called microabrasion.
This technique uses a mixture of fine particles of pumice and hydrochloric acid. This mixture is then placed onto your teeth and rubbed across the surface as many times as necessary.
The mixture starts to sand down and polish the enamel. The ultimate result is that the white spots will be less noticeable or completely gone afterwards because all new enamel is exposed. Microabrasion is a process that can be combined with other dental techniques in order to give you the brightest and most consistent smile possible.

White Spots on Teeth after Whitening

The procedure of teeth whitening is proven to be safe and effective; some may experience unwanted white spot on teeth after the procedure. Here’s what you need to know ahead of time about the possible appearance of white spots on your teeth.
(a.) Teeth whitening doesn’t cause white tooth stains, but if your teeth already have white stains caused by hypocalcification, then tooth whitening could make them more visible.
(b.) Hypocalcification is caused by exposure to too much fluoride (Fuorosis) a diet high in sugar or acid, heavy plaque, and often is visable when orthodontic bands and brackets are removed. Getting rid of these spots can be difficult, as some tooth whitening procedures can cause the hypocalcified areas to appear much whiter, making the difference in color even more apparent.
(c.) You may not be able to completely erase white stains on teeth, but there are other treatments available to possibly correct the discoloration of your teeth

Prevent future white spots on teeth after whitening by:

Keeping your teeth white requires regular maintenance. Stains can come back or be very stubborn. Your dentist will have you come in for future whitening treatments in addition to treating any other dental issues, like cavities. Daily care also goes a long way in preventing stains, including brushing twice a day. Whitening toothpaste can help remove stains and make sure your teeth stay healthy and bright.
A sparkling smile is attainable with diligent brushing, professional cleanings and whitening treatments.
Always check with your dentist first if you’re considering any type of whitening treatments, whether at home or in office, and to discuss the best options to minimize stains and enhance your smile.

How to get rid of White Spot on Teeth Overnight

There is several remedy that can help eliminate white spots, but the best procedure will depend on the severity of your condition and how much it costs to treat. Here are some options to discuss with your dentist:

1. Bleaching

Bleach-based tooth whitening can help balance the color of your tooth enamel. For the safest results, you need the whitening procedure or a dentist-supervised, take-home kit. Over-the-counter (OTC) bleaching products and whitening toothpastes are also available, but the result may take longer and not be as dramatic.

2. Brace regulation

If you or your child is wearing braces, help them brush and floss around these brackets and wires regularly to reduce the risk of white spots ruining the look of their straight teeth when they come off.

3. Stop smocking

Are you a smoker? Now is a good time to start the process of quitting.
4Toothpaste regulation
Children under the age of six can incur these spots too, and should therefore use only pea-sized amounts of fluoride toothpaste (make sure they don’t swallow).
Remarks:
Don’t let acute discoloration keep you from smiling. Like most oral issues, figuring out how to get rid of white spots on teeth may be easier than you thought.

What are the black spots on teeth? Get insights on the causes, how to remove and prevention mechanism.

What Causes Black Spots on Tooth

When our teeth are not the normal whitish or yellowish whitish color, they are said to be discolored. Black spots can occur anywhere on your teeth – be it on the front or at the back. They are caused by the erosion of the enamel on the teeth. These spot can be as tiny as a pen mark or big enough to cover a lot of the tooth surface.
Black spots on teeth may worry you, but there’s plenty ways you can go to fix them. Tooth decay caused by tartar can produce these black spots when your oral care is not quite up to the cleaning standard, and certain medical conditions can do so as well. Whatever the reason for your discoloration, your dentist or dental hygienist can offer a solution based on the cause.
It wound be a surprise if you find that you have other dental condition when a black spot are on your tooth. For instance you may find or notice your gums bleed more often when you have black spots on tooth.

Causes of Black Spots on Tooth

It is essential to find out what is causing the black spots. This will help you address the problem accordingly. The following are some of the factors:

1. Sugary food and drinking and carbonated beverages

Not only can sugary beverages like soda leave your teeth with block spots, they also make them vulnerable to decay, this type of beverage can cause an unsightly yellow tint to your teeth, which may make you too embarrassed to smile freely.
Staining from soda is mainly caused by two substances, phosphoric acid and chromogens. Phosphoric acid is added to soda for flavoring purposes. Although this ingredient is largely responsible for the flavor of soda as we know it, phosphoric acid weakens your tooth enamel that is a protective layer on the surface of your tooth.
Weakened enamel is more susceptible to the black spots on tooth and stain causing ingredients of various foods and beverages.
Chromogens give cola its color. Chromogens stain your teeth. When your tooth enamel has been eaten away by phosphoric acid, chromogens can easily cause a yellow, dingy tooth appearance.

2. Smoking Tobacco

Nicotine and tar are the two culprits in regard to tobacco stains on teeth. When tobacco is inhaled or placed in the mouth, nicotine and tar settle into the oral cavity. These substances are able to leach their way into microscopic openings in our enamel, resulting in black spots on tooth and yellow/brown discoloration of the tooth surface.
It is no secret that tobacco use is bad for your health. It is a commonly accepted fact that prolonged exposure to tobacco can cause a multitude of health problems and, in serious cases, fatal disease. What some people fail to realize is how tobacco cause negatively affects to their oral health.
Whether it is cigarettes, chewing tobacco, cigars or pipes, tobacco use wreaks havoc on your mouth in more ways than one. Aside from having tobacco stains on your teeth tobacco use will result in bad breath, gum disease, tooth loss and, more seriously, mouth cancer.
Quitting smoking is easier said than done, and it can become less satisfying when the stubborn yellow/brown tobacco stains linger on your teeth long after you have kicked the habit.

3. Tea or coffee

As a general rule, if a liquid can stain fabric, it can stain your teeth as well. What is more, while the overall health benefits of tea are generally undisputed, there’s actually evidence to suggest it may ultimately stain your teeth more than a traditional cup of Joe.
Despite the fact that your dark roast may appear to have more color than say, black tea, through naturally occurring tannins and processes such as oxidation, teas can really take to teeth, potentially leaving you  with black spots on teeth.

How to Prevent Black Spots on Tooth

1. You can prevent teeth stains from soda by:

• Reducing or eliminating the beverage from your diet.
• Using a straw to prevent contact between the soda and your teeth.
• Thoroughly rinsing your mouth with water after drinking soda.
• Drinking soda within a short period of time and then rinsing, instead of sipping slowly over an extended period of time.
• Teeth whitening by bleaching away these stains

2. Prevent black spots on tooth caused by tobacco smocking

• The most obvious way to prevent tobacco smocking black spots on tooth from occurring is to quit smoking, or never start in the first place.
• Maintaining a good oral hygiene routine by brushing at least twice a day, flossing each night before brushing and using an antiseptic mouthwash can help to prevent heavy staining and tar build-up, but it will not completely protect your teeth from discoloration caused by tobacco use.
• If you are unable to brush after each tobacco exposure, rinse thoroughly with water to remove as many harmful substances from your mouth as possible.
• It is important to visit your dentist for regular check-ups. Not only will the cleaning remove the stains, but your dentist and/or hygienist will do a thorough examination of all your oral tissues to ensure your tobacco use has not caused more serious problems.

3. How to clear black spots on tooth stained by tea and coffee

If you cannot give up on tea or coffee altogether is simply out of the question, I do have a few suggestions which can help mitigate hard to remove stains.

• Swish a glass of water around your mouth after ingesting a cup of tea or coffee
• Brew light coffee and add a small amount of cream or milk
• Change out your black tea bags for green or white tea
• Floss daily to remove plaque stains along your tooth’s edge
• Use a bit of baking soda and salt to lift surface stains, then rinse with hydrogen peroxide twice a week
• Brush with whitening toothpaste immediately after you finish the cup to keep stains from setting.

Note -Ultimately, I want to stress that, despite the potential for pesky stains, drinking tea is good for you. For example, Green tea contains the chemical compound fluoride which has been show to substantially strengthen teeth. It has been shown to kill bad breath causing bacteria and viruses in the mouth.
However, if in the end, you’re still uncomfortable with your smile after these preventive care measures, make an appointment to see a dentist if having your teeth bleached by a dentist is a good next step.

Brown Spots on Teeth  Reasons

Brown spots on the teeth occur when teeth get stained and they can be extremely embarrassing and can affect your smiles, self confidence and overall health. Apart from aesthetic reasons, it is important to get rid of brown spots and other stains for they could impact your health in many other ways.

What Causes Brown spots On Teeth?

There are two main categories of causes of brown spots on teeth

1. Internal reasons
2. external reasons

Either way, finding out the cause and treating it is important.

1. Decay:

Brown spots on teeth are a sign of tooth decay, which develops from snacking on sugary and starchy foods in excess. Beverages that are high in sugar do the same, creating plaque that sticks to the tooth surface and damaging it over time. If the plaque isn’t removed by regular brushing, it destroys the enamel and turns it brown. These brown spots may also come from the dentin underneath, which has a naturally darker shade when exposed by worn enamel.

2. Tartar:

When plaque builds up on teeth it hardens into a substance called tartar, which is often a brown color. Tartar often appears at the line between the teeth and gums, and regular brushing with toothpaste doesn’t remove it.

3. Fluorosis:

Fluorosis is caused by excessive fluoride intake, and in severe cases brown pits will appear on the teeth. Too much fluoride in the body, especially in kids whose teeth are still forming in the gum, discolors the tooth enamel. Permanent white lines or streaks often indicate mild fluorosis, whereas brown, gray or black patches and pits on top of an irregular tooth surface represent signs of more serious fluorosis. Although the teeth may look damaged, fluorosis is in fact only a cosmetic condition. Unless the teeth are decayed from another cause, they’re perfectly healthy.

4. Celiac Disease:

According to the celiac disease awareness campaign, the tooth enamel of those who have Celiac disease is often poorly developed. White, yellow and brown spots or bands may appear, and the enamel may be translucent. Because the effects are permanent, sufferers frequently opt for restorations to cover the condition.
Other Medical Conditions
High fevers and dental traumas can cause brown marks on teeth, and, albeit rarely, developmental conditions of the bones and skull have the same effect.
Prevention and Treatment

• For the long-term prevention of brown spots due to tooth decay and tartar, brush your teeth twice a day with thorough toothpaste such as, floss once a day and don’t eat sugary foods or snacks to tide you over between meals.
• Only a dentist can fix brown spots on teeth from decay. To do so, he or she removes the decayed area and replaces it with a filling. Keep in mind you can ask your dentist for white fillings that match your natural tooth color.
• A dentist or dental hygienist can remove tartar by scraping it away with special tools, and cleans and polishes the tooth enamel to perfect the final appearance.
• Brown spotting from fluorosis and Celiac disease is permanent and isn’t improved by whitening toothpastes or treatments. Removing the affected area isn’t appropriate if there’s no decay, but your dentist can cover stained teeth with veneers. Thin shells that cover the teeth, veneers can be matched to your natural tooth color.

Note-If your teeth have brown spots, ask your dentist for a checkup. The earlier the cause is found, the better the outcome for your oral health. Whether brown spots are due to decay, tartar or another condition, your dentist can help restore your confidence and your smile.

 Home Remedies for Brown Spots on tooth

Opting for professional treatment or taking matters in your own hands depends on the results desired, time at hand and cost. Natural home remedies with a myriad of benefits are milder, inexpensive but could take longer.

1. Teeth Whitening Pens

Whitening pens or brushes contain hydrogen peroxide smeared on to the surface of teeth. Once painted on black spots to tooth the solution is left on for 20 – 30 minutes.
After which it binds into a film that lasts for a certain amount of time.
This technique is good to treat individual teeth that have brown spots. It can be painted on as required to avoid the gums.

2. Whitening toothpaste

Whitening toothpaste can be effective in eliminating brown spots caused by caffeine and cigarettes. They contain chemicals and abrasives that can disperse these stains.
It can take around a month to make teeth appear whiter, if used twice a day. Toothpastes that contain ‘blue covarine’ can have a speedier whitening effect.
Note-Whitening toothpaste can’t change the natural color of teeth. It should be used with caution as it can weaken enamel.

2. Teeth whitening strips

Teeth whitening strips are a tray-free, convenient method, effective in displaying results. Most strips recommend a strip for 30 minutes a day for around 10 – 20 days.
It can also be done twice a day to speed up results.
These strips are transparent, fine and flexible layers of plastic that have been treated on one side with hydrogen peroxide. This enables effective whitening and reduces the chances of side effects.
Higher the strength of hydrogen peroxide and the longer the strip is worn the more effective in treating brown spots on tooth.

Black spots on Tooth no pain

This type of discoloration can be caused by too much exposure to fluoride, trauma or bruising of a tooth, or from some antibiotics such as tetracycline.

Brown spots on tooth near Gums

Healthy gums are firm, and cover the roots of the teeth. Usually the lower two thirds of a tooth are very much buried in the jaw bone.
Receding gums is a loss of gum tissue leading to the exposure of the roots of the teeth. Gum recession is a problem that might begin in the teens, but is very common in older adults. Gum recession is normally a progressive disorder that occurs day-by-day over several years.
This is why is very common over the age of 50. Most of the people do not notice that they have gum recession because it happens so slowly.
Many people don’t understand how to clean teeth properly leading to brown spots on teeth. Dentists may not have also been taught the most effective brushing technique in dental school (as proper teeth cleaning is very effective and reduces profitable dental problems).
Incorrect brushing or even flossing makes the bacteria to build up between the teeth and in the sulcus. Sulcular bacteria form the colonies and are the main reason for the development of gum disease and tooth decay.
Plaque is a soft, colorless biofilm that is formed by the mouth bacteria. If not removed, it tends to harden after a number of days and form calculus (tartar). Tartar is usually calcified mineral deposits on the teeth. It usually tends to stain much easily, and is visible as the brown or even the yellow stains on the teeth. It might also accumulate under the edges of the gums.
The most common bacteria that is associated with gum disease is porphyromonas gingivalis. An infection of the gums may lead to a chronic inflammatory response, which might contribute to the hardening and also narrowing of arteries (atherosclerosis), and a variety of other diseases depending on the individual.
Most of the doctors don’t make the connection between the periodontal disease and other chronic ailments, so they continue for several years.

How to get Rid of Black Spots on Tooth

Black spots on tooth can be removed using professional and at-home teeth whitening systems.
Various treatment solutions and whitening options at a dental hygienist can work on brown spots. Brown spots are largely extrinsic stains and in office procedures would take the form of polishing or teeth whitening treatments.

1. Dental Prophylaxis

Extrinsic stains are commonly cleaned through a dental prophylaxis treatment.
Prophylaxis has a dual action that cleans surface stains from teeth and protects teeth and gums from further damage or disease.
Procedure
Scaling – If there is minimal inflammation, the dental hygienist will start with scaling the teeth with an ultrasonic scaler to remove hardened plaque.
After this, a manual scalar is used to remove debris from in between the teeth.
Polishing – A prophy paste is then applied to thoroughly polish off superficial stains.
This technique is effective in treating stains and spots caused by tobacco, tea, coffee and other colored food.

2. Power Bleaching

Power bleaching uses a mix of hydrogen peroxide and bleaching gels to knock of stains and brighten teeth.
Bleaches can cause varying degrees of irritation, which is why the gums and mouth are separated using a protective ‘dental – dam’.
The technique then uses light to expedite teeth whitening. In this method, a whitening gel is applied on the teeth and a laser or led light is passed over it. This special light activates the whitening gel and quickly removes brown spots. A 30-60 minute session can offer very dramatic results, lightening teeth by 3-4 shades.

3. Porcelain veneers and composite bonding

For darker or persistent extrinsic stains, alternative options are recommended. Porcelain veneers and composite bonding are options that cover the teeth and mask cosmetic flaws.
Bonding is a good method to use when you have black spots on tooth. This method uses a composite resin on existing teeth and can cover stains and give you a natural smile. These require frequent cleaning – at least 4 times a year – since they can stain easily.

4. Porcelain veneers

Porcelain veneers are a preference to cover up stains and fix gaps in teeth. They’re a long-term solution and could be expensive. They consist of layers of many thin porcelain shells adhered to underlying tooth structure.
Veneers are made based on personal preferences and characteristics, to ensure a natural result. A minimal level of the tooth enamel is scraped off and the whole procedure might require a couple of sessions.
Porcelain veneers are newer techniques to hide stains. This is similar to bonding but uses porcelain laminated veneers on teeth that is more durable and does not stain very easily. It is more expensive when compared to bonding.

5. Composite bonding

This could last anywhere from 3 – 10 years. Composite veneers hide spots and stains in teeth with plastic resin, bound to fillers such as quartz and glass then fixed to the enamel.
They’re made with the help of a shade chart that ranges in colors and translucencies.The procedure is reversible, as underlying tooth structure remains untouched.
