Sealants applied early, and kept in place, prevent tooth decay. Period.
Next to in-office fluoride treatments, Dental Sealants represent the best value modern preventive dentistry has to offer.
Because decay on back teeth commonly begins in the grooves, pits, and fissures on the chewing surfaces of teeth, Sealants are “painted” on those biting surfaces and protect against decay.
Of course Sealants don’t eliminate all cavities, so it’s important to brush, floss, and see your Hygienist regularly to prevent decay on the sides and between teeth.
