Sealants are placed on teeth to help prevent dental decay. Teeth that have deep grooves are susceptible to decay because the bacteria that cause decay can hide in the grooves of the teeth and cannot be easily removed with brushing or flossing. Most commonly, sealants are placed on the biting surfaces of molar teeth. This picture shows a molar tooth in a Young child.
