Fissure filling is a completely painless intervention in which the biting surface of the tooth is coated with a special material. First, there is a complete cleaning of the tooth that is being filled, and then the tooth is treated with acid. Under the action of the acid, the smooth surface of the tooth turns into a rough one, and this enables the bonding of the filler that is applied to the tooth. Filling fissures reduces the risk of caries. The entire procedure lasts about fifteen minutes and after the treatment is over, it is possible to consume food and drink immediately.
