More than 75% of dental decay begins in these deep grooves. Teeth with these conditions are hard to clean and are very susceptible to decay. A sealant protects the tooth by sealing deep grooves, creating a smooth, easy-to-clean surface.

Sealants can protect teeth from decay for many years but need to be checked for wear and chipping at regular dental visits.

Reasons for sealants:

• Children and teenagers – As soon as the six-year molars (the first permanent back teeth) appear or any time throughout the cavity-prone years of 6-16.
• Adults – Tooth surfaces without decay that have deep grooves or depressions.
• Baby teeth – Occasionally done if teeth have deep grooves or depressions and child is cavity prone.
