Dental sealants are a protective coating applied to the chewing surfaces of the back teeth to shield them from decay caused by bacteria and food particles. These clear or tooth-colored sealants create a smooth surface that is easier to keep clean, filling in the natural pits and grooves where food and plaque can get trapped. Sealants are an effective preventive measure for children and teenagers, whose newly erupted permanent molars are most susceptible to cavities. By sealing these vulnerable areas, sealants can reduce the risk of decay by up to 80% in the first two years and continue providing protection for up to a decade. They are quick, easy, and painless to apply, making them an excellent investment in long-term oral health for young patients during their cavity-prone years.
