Dental sealants are plastic coatings that are usually placed on the chewing surface of the permanent back teeth to help reduce the risk of cavities.
The chewing surfaces of the permanent molar and premolar teeth have grooves that make them susceptible to decay. These grooves can be deep and are difficult to keep clean. Sealants provide extra protection for the grooves by providing a smooth surface.
Dental sealants should be placed as soon as the first permanent molars have erupted. This happens usually around the age of 12.
For more information on dental sealant treatments, please consult with your dentist or hygienist.
