What Sealants Do

A dental sealant is a thin coating applied to the chewing surfaces of the back teeth. It flows into the grooves and pits and hardens into a smooth, protective layer. Bacteria and food particles can no longer collect in those hard-to-reach spots.

Sealants do not replace brushing and flossing. They protect specific surfaces that are especially vulnerable to cavities, the grooved chewing surfaces of molars and premolars, and they work best as part of a consistent preventative routine.

The Process

Applying a sealant is straightforward. The tooth is cleaned and dried, a conditioning solution is applied to help the sealant bond, and the sealant material is painted onto the tooth surface. A curing light hardens it in seconds.

No drilling. No anesthetic. The appointment is quick and done in a single visit. Sealants are checked at routine exams and can be reapplied if worn or chipped.

Who Benefits

Sealants are most often recommended for children and teenagers whose permanent molars have recently come in. The years right after eruption carry the highest cavity risk, and a sealant applied early can protect those teeth through the most vulnerable period.

Adults with deep grooves and no existing fillings or decay in those teeth may also benefit. The hygienist or dentist will evaluate whether sealants are appropriate at your exam.
