Sealants are thin, plastic coatings painted on the chewing surfaces of the back teeth. By covering the chewing surfaces of the molars, sealants keep out the germs and food that cause decay. They can be put on in dentists' offices, clinics, and sometimes in schools.

Sealants are painted on as a liquid and quickly harden to form a shield over the tooth. The process is simple and painless. They are clear or tinted. Tinted sealants are easier to see.
