Fissure Sealants

Fissure sealants protect children’s teeth from tooth decay

A sealant is a clear plastic coating, which is applied to the biting surfaces of the back teeth. For fissure sealants to be effective, they need to be applied to your child’s permanent teeth as they emerge, usually starting around six or seven.

Back teeth have narrow grooves called ‘fissures’ and small pits on their chewing surfaces. No matter how well they are brushed, bacteria can still collect within them and eventually cause decay. A fissure sealant when applied to a tooth, helps stop food particles and bacteria from settling in these hard-to-clean grooves and pits.

What does the treatment involve?

The process is usually quick and straightforward, taking only a few minutes for each tooth, without the need for any anaesthetic or drilling. The tooth is thoroughly cleaned, prepared with a special etchant solution, and dried. The liquid sealant is then applied and set hard by shining a bright curing light onto it. It quickly bonds to the surface, forming a tough coating. Your child will be able to eat or drink straight away after treatment.

How long do fissure sealants last?

Sealants can last for many years, but regular check-ups are necessary to ensure they continue to remain intact. They can wear over time, and sometimes the dental team needs to add or replace some sealant to be sure that no decay can start underneath it.
