If sealants are lost, are the teeth more susceptible to decay?

• A. Yes
• B. No
• C. Sometimes
• D. Not possible to determine

Answer: (B)

Sealants provide a protective barrier in the pits and fissures of teeth, reducing plaque retention and limiting acid contact with enamel. When that barrier is lost, the grooves become exposed again to cariogenic bacteria and fermentable sugars, so the risk of pit-and-fissure decay increases. In practice, losing a sealant means the tooth returns to its untreated state, with higher susceptibility to decay unless preventive measures are quickly restored and continued (such as re-sealing, good hygiene, and fluoride exposure).
