Fissure sealing is a noninvasive preventive treatment, where the pits and fissures of posterior teeth are filled with materials specifically designed for this purpose, assuring the long-term protection from cavities. The procedure is simple and painless, and does not require anesthesia, scraping or removal of enamel. It doesn’t last long and the benefits are multifaceted. With proper oral hygiene, fissure sealants represent an additional effective method of protecting teeth from cavities.
