Dental sealants act as a barrier to protect the teeth against decay-causing bacteria. A dental sealant is a plastic material that is usually applied to the chewing surfaces of the back teeth. This plastic resin bonds into the depressions and grooves of the chewing surfaces of back teeth. The sealant acts as a barrier, protecting enamel from plaque and acids.
Sealants are easy to apply, and it takes only a few minutes to seal each tooth. The teeth that will be sealed are cleaned. Then the chewing surfaces are roughened with an acid solution to help the sealant adhere to the tooth. The sealant is then ‘painted’ onto the tooth enamel, where it bonds directly to the tooth and hardens. Sometimes a special curing light is used to help the sealant harden.
Sealants are an option for any age. If you are interested in adding extra preventative care to your teeth, Dr. Cannon may suggest sealants as part of your treatment.
