Dental Sealants for Children: Protection Against Cavities

An Extra Layer of Protection

Dental sealants are thin protective coatings applied to the chewing surfaces of back teeth (molars). At FB Dental Yarrabilba, we recommend sealants for children as an effective, painless way to prevent cavities in teeth most vulnerable to decay.

Why Back Teeth Need Protection

Molars have deep grooves and pits where food and bacteria accumulate. These areas are difficult to clean effectively, even with good brushing technique. Sealants fill these grooves, creating a smooth surface that's easier to clean and blocking bacteria from settling.

When to Apply Sealants

The best time for sealants is shortly after permanent molars emerge—typically around ages 6 and 12 when first and second molars appear. Applying sealants early, before decay has a chance to start, provides maximum protection. We may also recommend sealants for baby molars in high-risk children.

The Sealant Procedure

Application is quick, painless, and requires no drilling or injections. We clean and dry the tooth, apply a conditioning gel, rinse and dry again, then paint on the sealant material. A curing light hardens the sealant in seconds. The entire process takes just a few minutes per tooth.

Effectiveness and Longevity

Research shows sealants reduce cavity risk in treated teeth by up to 80%. They typically last several years, though we check them at each visit and can reapply if needed. Combined with good brushing, fluoride, and regular check-ups, sealants are a powerful preventive tool.
