What is the primary purpose of dental sealants?

• A. Seal crowns to improve aesthetics
• B. Seal pits & fissures to prevent caries
• C. Fill tooth decay lesions
• D. Protect gums from bacteria

Answer: (B)

Dental sealants are meant to protect the chewing surfaces of teeth by blocking food particles and bacteria from getting into the grooves. The main idea is to seal pits and fissures—especially on molars and premolars—where decay tends to start because these grooves are hard to clean. By bonding a thin resin to etched enamel and curing it with light, a smooth, sealed surface is created that reduces plaque buildup in those vulnerable crevices. This preventive measure is most beneficial soon after the teeth erupt, particularly in children and teens. Sealants don’t seal crowns, fill decay, or directly protect the gums; their purpose is to prevent caries by keeping the pits and fissures closed off from cariogenic plaque.
