Fissures are the thin grooves on the chewing surfaces and no matter how well they are brushed, bacteria can still collect within them 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 these hard-to-clean 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
  • Invisible 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 a special solution.
  • After rinsing off this solution and drying the tooth, the sealant is applied with a brush.
  • A curing light is used so the sealant will harden and quickly bond with the surface, forming 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. However, treated teeth will have smoother surfaces, so they will be much easier to keep clean.Sealants can last for many years but regular check-ups are necessary to ensure they continue to remain intact.
