A dental sealant serves the primary function of preventing caries, particularly in children and adolescents who are at a higher risk of tooth decay. Sealants are applied to the occlusal surfaces of molars and premolars, where food particles and bacteria are more likely to accumulate due to the tooth's grooves and pits. By creating a barrier that seals these vulnerable areas, sealants significantly diminish the likelihood of plaque accumulation, thereby reducing the risk of cavities forming. This preventive measure is particularly effective because it is a non-invasive procedure that can be easily applied in a dental office. It is important to emphasize that dental sealants do not treat existing cavities, whiten teeth, or replace enamel, which distinguishes their role as a preventive rather than restorative dental treatment.
