What is fissure sealant?
Fissure sealants are a preventative dental treatment to protect your teeth from tooth decay. This is usually done on the chewing surface of the back teeth (molars) with deep grooves (fissures). The layer of thin sealants prevent food and plaque from getting trapped in the deep pits and grooves; which can easily lead to tooth decay. A study shows a 76% reduction in decay when the molars are fissure sealed (1).
How is it done?
When should this be done?
Fissure sealants are generally done for children and teenagers. They are usually applied soon after the first permanent molars have come through at around 6-7 years old; and second permanent molars at around 12 years old. This is the best time to have fissure sealant done as the enamel on those newly erupted teeth are at its weakest and we all know kids like sweet foods.
How long does it last?
Fissure sealant can wear over time, but generally it can last for many years. Regular dental check-up can help to ensure that the sealants are intact.
