Sealants help prevent tooth decay and cavities. Your teeth are coated with a sticky film of bacteria, called plaque. Bacteria turn the sugar in what you eat and drink into acids that can break down the hard, outer layer of teeth, called enamel. Over time, the acid can weaken the enamel and may cause tooth decay, or a hole to form in your tooth's enamel (cavity).
Tooth decay often begins on the chewing surfaces of the back teeth. These surfaces have pits and grooves where plaque, bacteria and bits of food can get trapped. Toothbrush bristles can't reach into the pits and grooves, and it makes it hard to keep them clean.
Dr. Suntrup may recommend dental sealants to keep decay from starting on these chewing surfaces in the pits and grooves.
Sealants are not a substitute for cleaning your teeth every day! They only help prevent decay if you stick to your daily oral hygiene routine.
