Fissure Sealants


What are Fissure Sealants?

Fissure sealants are a safe and painless way of protecting children’s teeth from decay.

Which teeth should be sealed?

Fissure sealants are only required on the back biting teeth i.e. molars and premolars. These teeth can have deep pits and fissures which can trap bacteria and be difficult to clean, leading to tooth decay. However, some teeth have shallow fissures so do not require fissure sealants. This treatment is most effective as a preventative measure when the teeth are newly erupted in to the mouth.

The treatment process

The treatment process for sealing pits and fissures is completely pain free and teeth won’t feel any different after the procedure.

The process begins by cleaning the biting surfaces (fissures) before a solution is applied to the tooth to aid the bonding of the sealant. The solution is washed out of the mouth after use, following which the tooth is dried. The dentist will then place the sealant on the tooth, filling the gaps and grooves to ensure a smooth finish. The sealant will then be set with a bright blue light.

Long-term dental hygiene

Fissure sealant provides effective protection of the pits and fissures on the biting surfaces of back teeth. However, it is important that children maintain their normal brushing routine at home alongside this treatment. Decay can still occur if good oral hygiene is not maintained.
