The Benefits of Sealants for Your Child’s Teeth

Normal pits and grooves on the chewing surfaces of back teeth can trap food that can't be removed by brushing or washed out by water or saliva. A sealant is a tough, plastic material designed to bond (stick) to tooth enamel and cover of the pits and grooves.
Sealants are a clear or tooth-colored material that is painted onto the tooth surface to "seal" the pits and grooves and protect against decay. They are generally applied to children's first permanent back teeth but are beneficial in any tooth with deep grooves and a high risk of cavities.
Sealants are an excellent way to protect chewing surfaces of teeth from decay. They are a much better financial investment than treating decay after it has started.
Sealants are not permanent. They generally last about five to ten years with normal wear but can wear off or chip off earlier in certain instances. Also, sealants do not prevent decay between teeth or the onset of gum disease, so regular home care and dental visits are important.
