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. The first molars usually come into the mouth when a child is about 6 years old. Second molars appear at about age It is best if the sealant is applied soon after the teeth have erupted , before they have a chance to decay. Applying sealants does not require drilling or removing tooth structure. The process is short and easy. Firstly the tooth surface is thoroughly cleaned with a paste and rotating brush by the dentist or hygienist. Next the tooth is washed with water and dried. This creates small microscopic areas and a fine rougher surface than the surrounding tooth enamel, that can be seen with a microscope. The rough surface and microscopic areas enable the dental sealant to attach to the tooth. After the tooth is dried again, the liquid dental sealant is placed on the tooth and hardened.
