White Patches on Teeth - Causes and Management.

White spots are spots which are visibly whiter than the rest of the teeth. These are not major medical concerns and they are not even clearly visible unless you look closely. However, some people may still want it removed as they think it looks bad. Here is everything you need to know about the causes and management of white spots that appear on your teeth.


1. Fluorosis: This is the most common cause of white spots. Fluorosis is a condition in which the enamel of the tooth gets damaged because of too much fluoride. Fluorosis only happens in children. Even though fluoride helps prevent tooth decay, it is crucial to not take too much before the teeth have developed as you might get fluorosis.

2. Dry mouth: When your mouth is dry, it doesn’t have enough saliva to keep the pH level of your mouth neutral. When pH level is not right, bacteria grow and survive to attack your teeth with their acid.

3. Braces: Not taking proper care of the teeth when you have braces can result in white spots after the braces come off.

4. Hypoplasia: The loss of mineral in the teeth is known as hypo calcification. The white spots which appear due to this are known as hypoplasia.

5. Poor Oral Hygiene: If you don’t take enough care to clean your mouth, plaque will build up there on your teeth. Plaque can be understood as the sticky, colorless film of bacteria and debris that forms on your teeth just after you finish eating carbohydrates that mean all the sugars and starches you have. These bacteria then feed on these sugars and produce acid that damage your teeth’s enamel causing white spot and then tooth decay.


1. Composite Filling: Occasionally, if the white spot is only within enamel it can be filled with a composite filling to match the rest of the tooth.

2. Veneers: Another way to conceal white spots is veneers – be it ceramic or composite veneers, provided the White spot doesn’t cover the entire tooth surface and there is enough healthy enamel to stick the cosmetic veneer on. Preferably in cases where a person is more conscious and the white spots exist on multiple teeth.

3. Air Abrasion Procedure: This is a procedure used only if bleaching does not work. In it, crystal particles are blown towards the teeth at high speeds, which result in removal of the calcium deposits.

White Spot Prevention Methods:

Preventing the onset of white spots is the best line of action you can take. You can start by practicing good oral hygiene. You must brush and floss your teeth at least twice a day and visit your dentist after every six months for a regular dental check-up. Also, you should try to avoid acidic and sugary drinks and foods that can damage your tooth enamel. Moreover, if you wear braces then, you must make additional effort to take excellent care of your teeth so that when the braces are removed to expose your straightened teeth, you do not catch sight of unpleasant spots on your tooth.
