How Sealants Are Placed
Applying sealants is a very simple and painless procedure. Since children are involved, and they may be scared of any treatment, your child can be assured that it is more like a paint-on procedure which will save him or her from possible drilling later. As enamel has no nerves, a procedure outside the enamel will cause no pain.
The procedure starts with a minute examination of the teeth to be sealed. Any minute traces of plaque are removed gently, and the tooth surface cleaned and dried. An ‘etching’ solution is applied which serves to roughen the surface for better adherence of sealants. The tooth is rinsed and dried again. The sealant in the form of a liquid is painted on to the desired surfaces and takes about a minute to harden. A special curing light may be used.That completes the sealing action.
The BPA issue
Some concern was generated by a report I 2012 that bisphenal-A (BPA) chemical present in some dental sealants in trace amounts might be linked with behavioral problems in children. However, the fears are unfounded. Far more BPA is present in food and beverage packaging, The American Academy of Pediatric Dentistry and the American Dental Association continueto support the use of sealants.
Taking Care of Sealants
Sealed teeth give your child added protection against tooth decay. They require no special care except routine hygiene practice (twice daily brushing and flossing), and regular inspections by the dentist. Sealants should last about ten years, but should be monitored for possible wear and tear during routine inspection visits.
