Protective treatment for younger teeth
Fissures are the thin grooves on the chewing surfaces of teeth. 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 six and seven years old.
