What are Fissure Sealants?

Fissure sealants consist of a very thin plastic coating that is painted onto the chewing surfaces of back teeth, sealing these surfaces so bacteria cannot get in. Treatment is highly effective at helping to reduce the risk of cavities in these teeth as they are particularly vulnerable to decay. If you look at these surfaces, you’ll notice they are pretty intricate, with lots of fissures and grooves that help grind up food so it can be digested more effectively. Unfortunately the fissures are excellent at trapping food particles, as well as decay causing bacteria, and it can be difficult to thoroughly clean these surfaces.

Most cavities in children’s teeth develop in their back teeth, which is why Blue House Dental recommends sealing adult teeth as soon they erupt. Fissure sealants can only be applied to teeth that do not have any cavities or fillings. If a child is particularly prone to tooth decay, or if they have very deep fissures in their milk or primary teeth, then we might recommend fissure sealants to help prevent these teeth form being lost too early.

What is the Procedure for Fissure Sealants?

The procedure for fissure sealants is very straightforward and quite quick, and can be completed in one visit. We’ll need to thoroughly clean your child’s teeth before drying them. The next step is to paint on a solution that etches the tooth surfaces due to be sealed. This helps to create a better bond between the fissure sealant and the tooth. Once the etching fluid is washed off, we will dry the tooth surfaces before painting on the fissure sealants.

We will check the condition of the sealants at each appointment as they do need renewing periodically, usually after five to ten years. Fissure sealants are a great preventative dental care treatment for keeping your child’s back teeth healthy and cavity-free.
