Dental sealants are protective barriers against decay.
Dental sealants are protective barriers applied to the premolars and molars of the teeth. Sealants are made of a plastic resin that bond to a tooth’s depressions and grooves to help create a barrier for the hard to reach places from plaque and acid. Sealants are normally given at an early age to children to protect their teeth and then are reapplied later on when the sealants have been worn down. However, sealants take many years to wear down enough that they need replacing. Sealants do not mean that brushing can be ignored, but are a supplement to regular brushing and flossing as well as twice-yearly dental cleanings for keeping a healthy mouth.
