Why Should a Child Have Fissure Sealants?

The flat chewing surfaces of back teeth have many intricate grooves and fissures that can easily trap food and bacteria and which may be too deep to keep thoroughly clean. Fissure sealants are a simple, cost-effective and non-invasive way to protect these tooth surfaces from developing cavities.

What are Fissure Sealants?

Fissure sealants are made from a special type of resin, very similar to the composite resin used to make tooth restorations, but in a much thinner consistency so the sealant can be painted onto the teeth surfaces. This increased viscosity allows the sealant to flow into all the grooves in the tooth surfaces, completely sealing it so bacteria cannot penetrate. The sealant soon hardens or we can accelerate this process with a special light. Once hardened, it forms a virtually invisible thin layer of plastic over the tooth surfaces that does not interfere with the bite, but which creates a smooth, easy-to-clean area.

How Long Will Fissure Sealants Last?

Fissure sealants should last for many years before they require repairing or replacing. We do regularly check their condition to ensure they are still continuing to provide a good level of protection to your child’s teeth.
