The main concept is that sealants protect teeth by creating a physical barrier over pits and fissures, preventing plaque, sugars, and bacteria from accumulating in those narrow grooves where decay often starts. When a sealant is applied to the grooves of eruption-prone molars, it bonds to the enamel and fills the deepest fissures, making the surface easier to clean and much harder for caries-causing organisms to reside in. This reduces the initiation and progression of caries in areas that toothbrush bristles may not reach effectively. Some sealants may release fluoride to support remineralization, but their primary benefit is the barrier they create. Sealants are an adjunct to good brushing and fluoride use, not a replacement for them; if a sealant chips or wears away, the protected groove can again harbor decay, so regular checkups and reapplication when needed are important.
