The chewing surfaces of back teeth contain natural pits and grooves that can be extremely narrow. Food particles and bacteria may become trapped within these areas, sometimes beyond the reach of toothbrush bristles.
Dental sealants create a protective barrier over these vulnerable surfaces.
At John E. Sullivan DDS, P.C., sealants may be recommended particularly for children and teenagers whose permanent molars have deep grooves or are at increased risk for tooth decay. Certain adults may also benefit from sealants.
The procedure is conservative and generally does not require drilling or local anesthesia.
The tooth is cleaned and isolated from moisture. The surface is prepared so that the sealant material can bond to the enamel. A thin resin material is then placed into the pits and grooves and hardened using a dental curing light.
Once completed, the sealant creates a smoother surface that is easier to keep clean.
Sealants do not eliminate the possibility of developing cavities and do not replace brushing, flossing, fluoride exposure, or regular dental examinations. However, when appropriately placed and maintained, they can significantly reduce the risk of decay on susceptible chewing surfaces.
Sealants are checked during future examinations and can be repaired or replaced when necessary.
