What is a Dental Sealant

Dental sealants are thin, plastic coatings placed on the chewing surfaces of the permanent molars (back teeth). The biting surfaces on molar teeth are where most cavities occur in children. By placing dental sealants on these surfaces, the tooth is protected by keeping out pieces of food and germs that can cause cavities.

Dental Sealant Before and After

Sealants are completely painless and do not require drilling or shots of any kind. Sealants are placed by first cleaning the tooth and removing all liquid surrounding the tooth. The sealant material is applied using a very small tube. The material is hardened using a light that is placed on the tooth for a few minutes. When the material is hardened, the sealant is mostly white and blends in with the tooth. For more information on dental sealants, how they are applied, and how they promote oral health in children, visit the Center for Disease Control (CDC) website for answers to frequently asked questions on dental sealants.
