Dental Sealants

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, and can be narrower than even a single bristle of a toothbrush. Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Fluoride helps prevent decay and helps protect all the surfaces of the teeth. Dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.

Dental sealants are resin composite 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.

Dental sealants have been used and proven to be effective since the 1970s. They are shown to help prevent decay on chewing (occlusal) surfaces. Dental sealants can last many years. It is also possible to replace a dental sealant if one has become damaged or lost.
