Sometimes it gets difficult for your toothbrush to reach small grooves in your teeth. If left these tiny areas develop tooth decay. Sealants give your teeth extra protection against decay and help prevent cavities.
Dental sealants are resins that bond and harden in the deep grooves of the tooth surface. After sealant application the tiny grooves (on biting surfaces of the back teeth) become smooth, don’t harbour plaque and brushing becomes easier & effective.
Sealants are applied to child's teeth after permanent teeth have erupted, as a preventive measure against tooth decay. However, adults may also receive sealants on healthy teeth.
The process is usually quick and straightforward taking only a few minutes per tooth. The tooth is thoroughly cleaned, prepared with a special solution, and dried. The liquid sealant is then applied and allowed to set hard – usually by shining a bright light onto it. It is totally pain free.
Sealants usually last for 3 to 5 years, but the dentist should check them regularly to make sure that the seal is intact. They can wear over time, and sometimes the dentist needs to add or replace some sealant to be sure that no decay can start underneath them.
