A fissure seal is a thin protective coating placed over the deep grooves, or fissures, of a tooth.
Some teeth naturally have very deep grooves where plaque and food can collect, making these areas difficult to clean and more susceptible to decay. We clean and prepare the tooth before applying the fissure seal over these grooves and setting it in place.
Because fissure seals are quite thin, they can gradually wear over time. We check them at your regular six-monthly appointments and can repair or replace them when necessary.
