Dental Sealant FAQs

Dental sealants are thin coatings that when painted on the chewing surfaces of the back teeth (molars) can prevent cavities (tooth decay) for many years. Sealants protect the chewing surfaces from cavities by covering them with a protective shield that blocks out germs and food. Once applied, sealants protect against 80% of cavities for 2 years and continue to protect against 50% of cavities for up to 4 years.

A cavity is a permanent hole in a tooth. If it is not treated, it will get bigger; it can hurt and get infected. The most common place for cavities is in the grooves of the back teeth.

Sealants are a quick, easy, and painless way to prevent cavities. A tooth without a cavity is stronger and healthier than a tooth with a filling or untreated decay. Sealants are also less expensive and easier to apply than fillings.
