What They Are
Dental fissure sealants are thin, plastic films painted on the chewing surfaces of the back teeth and are highly effective in the prevention of tooth decay.. Sealants provide a physical barrier so that cavity-causing bacteria cannot invade the pits and fissures on the chewing surfaces of teeth. Dental sealants are particularly effective on the back teeth, as the back teeth contain more hard-to-reach pits and grooves that serve as a host to food debris and plaque build-up.
In addition, sealants help to maintain the ongoing health of teeth. Each time a tooth is filled due to tooth decay, additional tooth structure is lost. Fillings commonly last an average of six to eight years, after which time they need to be replaced. Therefore, sealants often save time and money and reduce the discomfort associated with dental treatment procedures.
In most cases, Fissure Sealants provide 100 percent protection because they act as a physical barrier to decay and plaque build-up. In addition, sealants are believed to actually stop cavities when placed on top of a slightly decayed tooth by sealing off the supply of nutrients to the bacteria that causes the cavity. The dental sealant becomes ineffective when all or part of the bond between the tooth and the sealant is broken.
Newly erupted, permanent teeth in children are most susceptible to cavities. This makes them ideal candidates for Sealants. We at Happy Smile Dental Clinic believe that sealants should be used as part of a child’s total preventive dental care. A complete preventive dental program includes use of sealants, fluoride, plaque removal, careful food choices, and regular dental care.
However, the benefits of Sealants is not restricted to children alone and patients of all ages can benefit from them.
The procedure for applying a dental sealant is shown in the video below.
The procedure starts with cleaning the surface of the tooth,
A solution or gel is then applied to the surface of the tooth, including the pits and grooves, to make the surface of the tooth rough.
After several seconds, the solution is thoroughly rinsed away with water and the site is dried.
The liquid sealant is then applied and allowed to harden often using a light.
