Which option is a clear or white acrylic applied over the biting surface to prevent decay?

• A. Sealant
• B. Crown
• C. Bridge
• D. Bleaching

Answer: (A)

Sealants are a preventive resin placed on the chewing (occlusal) surfaces of molars and premolars to keep pits and fissures from collecting plaque and bacteria. They’re typically clear or tooth-colored acrylic, and once bonded and cured, they form a smooth barrier that makes those grooves much easier to clean and less prone to decay. The procedure is quick, painless, and especially useful for children and teens as a preventive measure because decay most often starts in those deep grooves. The other options don’t provide this surface protection: a crown covers and restores a tooth, a bridge replaces missing teeth, and bleaching whitens teeth rather than preventing decay on biting surfaces.
