Dental sealants are a fast, highly effective way to protect teeth from oral bacteria. Sealants act as a barrier between your molars and the plaque in which the bacteria live. The chewing surfaces of molars are covered with deep folds and fissures that can be difficult to keep clean. Some of these fissures are so narrow that toothbrush bristles cannot even fit inside them, which means that you may not be able to remove all the plaque and food debris that gets in them. Over time, the enamel in the folds can decay, and a cavity will form.
Our dentist can use a dental sealant to protect the surface of the molar and seal off the fissures and folds of the tooth. The sealant is made of a special plastic resin material and is painted directly onto the molars and premolars after they have been professionally cleaned. The resin is cured with a special light that hardens it quickly, and it will stay in place for years before needing to be reapplied. While sealants do not take the place of good dental hygiene habits, they can help protect the deep pits and fissures of your molars against the decay that commonly begins there.
