Dental Sealants

Dental Sealants
Dental sealants are plastic coatings that are usually placed on the chewing (occlusal) surface of the permanent back teeth — the molars and premolars — to help protect them from decay. The chewing surfaces of the molar and premolar teeth have grooves — “fissures” — that make them vulnerable to decay. These fissures can be deep, are difficult to clean,  Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. 

Dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.  The first dental sealant to be placed is usually on the fissure of the first permanent molar tooth, once the chewing surface of the tooth has erupted completely beyond the gum
