What Is A Dental Sealant?
Dental caries (tooth decay) is the most wide spread dental disease among children and adults. However, Dr. Barry and Dr. Love can reduce the incidence of decay by applying sealants to your teeth.
Dental sealants are clear or tooth colored plastic films painted on the chewing surfaces of molars and premolars (the teeth directly in front of the molars) where decay occurs most often. Sealants have been shown to be highly effective in the prevention of cavities. This sealant acts as a barrier, protecting the decay-prone areas of the back teeth from plaque and acid.
How effective are sealants?
Scientific studies have shown that properly applied sealants are 100 percent effective in protecting the tooth surfaces from caries. As long as the sealant remains intact, small food particles and bacteria that cause cavities cannot penetrate through the sealant. In fact, research has shown that sealants actually stop cavities when placed on top of a slightly decayed tooth by sealing off the supply of nutrients to the bacteria that causes a cavity.
Sealants no longer protect teeth if part or the entire bond between the tooth and sealant is broken. However, clinical studies have shown that teeth that have lost sealants are no more susceptible to tooth decay than teeth that were never sealed.
How are sealants applied?
Sealant application involves cleaning the surface of the tooth and rinsing the surface to remove all traces of the cleaning agent. An etching solution or gel is applied to the enamel surface of the tooth, including the pits and grooves. After 15 seconds, the solution is thoroughly rinsed away with water. After the site is dry, the sealant material is applied and allowed to harden by using a special curing light.
Other sealants are applied and allowed to harden much the same way nail polish is applied to fingernails. Sealant treatment is painless and can take five to 45 minutes to apply, depending on how many teeth need to be sealed. Sealants must be applied properly for good retention.
How long will a sealant last?
Sealants should last five years, but can last as long as 10 years. One study reported that seven years after application, an impressive 49 percent of treated teeth were still completely protected. Sealants should not be considered permanent. Regular dental check-ups are necessary to monitor the sealants’ bond to the tooth.
Who should receive sealant treatment?
Because children they have newly erupted, permanent teeth, they receive the greatest benefit from sealants. The chewing surfaces of a child’s teeth are most susceptible to cavities and the least benefitted by fluoride. Surveys show that approximately two-thirds of all cavities occur in the narrow pits and grooves of a child’s newly erupted teeth because food particles and bacteria cannot be cleaned out.
Other patients also can benefit from sealant placement, such as those who have existing pits and grooves susceptible to decay. Research has shown that there is a 95 percent chance that nearly everyone will experience cavities in the pits and grooves of their teeth.
Are sealants covered by insurance?
Although insurance benefits for sealant procedures have increased considerably, coverage is still minimal. The trend is toward expanded coverage of this benefit, especially as companies start to realize that sealants are a proven preventive technique. This preventive measure can help reduce future dental expenses and protect the teeth from needing more aggressive forms of treatment.
