Our back teeth (molars and premolars) have deep grooves, called pits and fissures, which make them vulnerable to decay. Food particles and bacteria can get lodged and stuck in these narrow spaces. A single toothbrush bristle is too big to fit and clean the grooves. Even with vigorous brushing, the acid from bacteria in the plaque attacks the tooth enamel and results in a cavity. Fortunately, dental sealants can help prevent such cavities.
Dental Sealants Bond to a Tooth’s Enamel
Dental sealants are an impenetrable, tough, yet thin plastic coating that is painted on the chewing surfaces of permanent back teeth. They bond to the enamel and create a smooth surface that is much less susceptible to decay. After an application, a blue spectrum of natural light is shone on the sealant material for a few seconds to cure it. Essentially, this “seals” the pits and fissures, protecting the grooves in the teeth from food getting caught in them and leading to decay.
For Adults as well as Kids
We normally apply sealants to children’s first permanent molars. However, we have plenty of adults who are benefiting from this simple, quick and painless procedure.
How Long do Dental Sealants Last?
While chewing, incredible pressures are placed on teeth. Although sealants can remain effective for three to five years or longer, they do wear away naturally and may need to be reapplied
