Dental sealants are a protective dental treatment designed to shield the chewing surfaces of teeth from decay and cavities. By applying a thin, plastic coating to the vulnerable pits and fissures of molars and premolars, dental sealants create a barrier against harmful bacteria and plaque buildup, significantly reducing the risk of tooth decay. This quick and painless procedure is particularly beneficial for children and adults with deep grooves in their teeth, offering an effective way to maintain a healthy and radiant smile for years to come.
