Dental Sealants

If you are concerned with preventing tooth decay and sensitivity, the dentists at Dr. Mady Group offer dental sealants.


A dental sealant is a plastic material used in dentistry to protect the surfaces of the teeth. Dental sealants are applied to decay-prone surfaces of the teeth, usually the back molars and pre-molars. Sealants come in the form of a liquid which quickly hardens to form a shield over these chewing surfaces.

Sealants keep out germs and food that can cause tooth decay. Food and germs can get stuck in certain areas because toothbrush bristles cannot brush them away. Food germs in the mouth change the sugar in food to acid which can start a cavity in the tooth. Sealants prevent decay from ever starting.

Who should get sealants?

Children can benefit from sealants on their permanent molars as soon as the teeth come in, before decay has a chance to attack the teeth.

Sealants also have an important role to play in older family members since adults can still get dental decay. Patients afflicted with dry mouth, which affects about one-third of the adult population, can benefit from sealants. Sealants can also protect worn and sensitive surfaces on adult teeth.

How are sealants put on?

First, we clean the teeth thoroughly so the surface is a little rough, which is easier for the sealant to bond. We rinse and dry the tooth again and the sealant is applied and hardens.
