When sealants are properly placed, they typically last how long?

• A. 1 to 2 years
• B. 3 to 5 years
• C. 5 to 10 years
• D. 10 to 15 years

Answer: (C)

When sealants are placed correctly, they form a durable barrier over the chewing surfaces, protecting deep pits and fissures from decay. The key is technique and material: proper isolation, clean etched enamel, good bonding, and a seal that remains well-adhered to enamel. Under these ideal conditions, sealants typically last five to ten years. They may wear or debond earlier if moisture contamination occurs, occlusal wear is excessive, or there is marginal breakdown, but five to ten years is the usual expectation. Regular check-ups help catch wear or loss early and reapply as needed.
