Dental sealants play a pivotal role in preventive dentistry by providing a protective barrier against tooth decay, particularly in children, adolescents, and adults.

These thin, plastic coatings are applied to the chewing surfaces of molars and premolars, where deep pits and fissures are prone to trapping food particles and bacteria. By sealing off these vulnerable areas, sealants effectively prevent the formation of cavities by inhibiting bacterial colonization and food retention. This proactive approach significantly reduces the risk of tooth decay, ultimately promoting long-term oral health and minimizing the need for invasive dental treatments.
