A sealant is a clear flowable material that is applied to the chewing surfaces (grooves) of the back teeth (premolars and molars), which are most susceptible to cavities. Sealants acts as a barrier to food, plaque and acid, protecting the teeth from cavity-causing bacteria. Dental sealants are applied to healthy teeth to prevent against tooth decay. The chewing surfaces of molars and premolars are particularly difficult to keep clean due to their deep grooves, pits and fissures.  Oftentimes plaque and food particles become trapped in these grooves and cannot be reached with just a toothbrush. Dental sealants are easily applied in the office and are a great way to your child’s teeth from getting cavities in the future.
