Fissure sealants are thin protective coatings applied to the chewing surfaces of back teeth. These areas can trap food and plaque, especially in children and teens. Sealants help reduce cavity risk by covering deep grooves where brushing may not reach easily.
Don’t ignore the signs — early treatment is faster, simpler, and less costly.
Deep fissures in back teeth make them harder to clean and more prone to decay.
A history of repeated cavities suggests your teeth may benefit from added protection.
If standard brushing leaves back teeth feeling unclean, sealants provide additional coverage.
Dry mouth, diet, or genetics can increase decay risk — sealants help reduce it.
