1. 2 years

2. 3 years

3. 5 years

4. 7 years

The correct answer is: 5 years

Dental sealants typically last around five years on average. This duration can vary based on several factors including the type of sealant used, the patient's oral hygiene practices, and the level of wear from chewing. Sealants are designed to provide a protective barrier against decay in the pits and fissures of teeth, especially in molars where cavities are more likely to form. Regular dental check-ups can help determine the condition of sealants and whether they need to be reapplied. If maintained properly, some sealants may even last longer than five years, but five is the standard average established through studies and clinical observations in dental practice.
