The natural anatomy of molars and premolars includes deep grooves and pits that are perfect hiding spots for plaque and bacteria. These areas can be difficult to clean thoroughly with regular brushing and flossing, making them especially vulnerable to decay. Dental sealants act as a protective coating by sealing these grooves with a thin, clear resin. Applied by our experienced Lincolnshire dental team, this resin quickly hardens to form an invisible barrier that blocks out cavity-causing bacteria and acids, significantly reducing the risk of tooth decay.
