Fissure Sealants

The chewing surfaces of the back teeth have thin grooves known as fissures which can be difficult to keep clean.

No matter how well they are brushed, bacteria can still collect within these fissures and eventually cause decay. A fissure sealant is a safe plastic coating applied to the tooth to stop food particles and bacteria from settling in the narrow grooves.

This preventive treatment is normally given to children whose permanent teeth are starting to emerge, usually between 6 and 7 years. The application process is quick and easy, and there is no need for an anaesthetic or drilling.

Benefits

• Long lasting protection
• Painless treatment
• Not visible once applied

Treatment steps

• The tooth is polished to remove plaque and food debris from the fissure surfaces.
• The surface of the tooth is etched with as special solution and this is then rinsed off.
• After drying the tooth, the sealant is applied with a brush.
• A curing light is used so the sealant hardens and quickly bonds with the surface, becoming a tough coating

Aftercare

To ensure sealants offer the best protection, it is important they are used in conjunction with a comprehensive dental care routine that includes effective brushing, flossing and a healthy diet. Treated teeth, with their smooth surfaces, will be much easier to keep clean.

Sealants can last for many years but regular check-ups are necessary to ensure they remain intact.
