Dental sealants are thin plastic coatings that are applied to the grooves and fissures on the surfaces of the permanent molars to protect them from tooth decay. Most tooth decay in children and teens occurs on chewing surfaces of the permanent molars and therefore they are the most likely to benefit from sealants. Dental sealants are sometimes also used on other permanent teeth if they have grooves or fissures, to help protect these surfaces. In some children, the molars in the primary dentition also have grooves that could benefit from dental sealants and in this situation your dentist or hygienist may recommend dental sealants on the chewing surfaces of these primary teeth.

This creates small microscopic areas and a fine rougher surface than the surrounding tooth enamel, that can be seen with a microscope.
