What’s is a fissure sealant?

Fissure sealants are a safe and painless way of protecting your child's teeth from tooth decay. Essentially they are plastic coatings that are painted onto the chewing surfaces of the back teeth. This then forms a protective layer that prevents food and bacteria from getting stuck into the groves of the teeth. It also makes it easier for children to brush and clean thier teeth as the tooth takes on a flatter shape

What’s involved?

The process is usually quick and easy taking only a few minutes per tooth.

The tooth is thoroughly cleaned, prepared with a special solution, and dried. The sealant is then applied and allowed to set hard – usually by shining a blue light onto it.

How long does fissure sealant last?

Sealants usually last for many years, but needs to be checked regularly to make sure that the seal is intact. They can wear over time, and sometimes needs to be added to or replaced to be sure that no decay can start underneath it. At Edgware Dental Practice we will always check these at each check up visit.

When can they be done?

Resin-based fissure sealants should be applied to the permanent molars of all children as early after eruption as possible. This is usually betwen 6 and 7 but can depend based on the amount of tooth that has erupted and how well we feel the child will tolrerate the treatment.

Can they be seen?

Fissure selants done by our dentists are either clear or white and cannot be seen as they are on the back teeth so will not be visible when they smile.
