What is the primary purpose of pit and fissure sealants?

• A. To whiten teeth
• B. To prevent caries in pits and fissures
• C. To strengthen enamel
• D. To align teeth

Answer: (B)

Pit and fissure sealants provide a protective barrier on the chewing surfaces of the back teeth. By filling and sealing the deep grooves where plaque and food get trapped, they create a smooth surface that’s much easier to clean and less prone to acid attack and decay. That barrier specifically targets caries in pits and fissures, which are the areas most at risk because they’re hard to reach with brushing. They don’t whiten teeth, don’t strengthen enamel as a primary function, and don’t move teeth, so those options aren’t what sealants are for.
