Dental Sealants

A sealant is a thin, plastic coating applied to the chewing surfaces of molars, premolars, and any deep grooves (pits and fissures) of teeth. Over 75% of dental decay begins in these deep grooves, which are difficult to clean and highly susceptible to cavities. Sealants protect teeth by creating a smooth, easy-to-clean surface.

Sealants can last for many years but should be checked regularly for wear or chipping during dental visits.

Reasons for Sealants

  • Children and teenagers: Applied as soon as six-year molars appear, or during the cavity-prone years of ages 6–16.
  • Adults: Applied on tooth surfaces without decay but with deep grooves or depressions.
  • Baby teeth: Occasionally used if teeth have deep grooves or the child is cavity-prone.

Sealant Procedure

The application of sealants is quick and painless, taking only a few minutes per tooth:

  1. Teeth are thoroughly cleaned and isolated with cotton to keep the area dry.
  2. A special solution is applied to the enamel to help the sealant bond.
  3. Teeth are rinsed and dried.
  4. Sealant material is carefully painted onto the enamel to cover deep grooves or depressions.
  5. The material either hardens automatically or with the use of a special curing light, depending on the type of sealant.

Maintaining proper home care, a balanced diet, and regular dental visits will help maximize the longevity of sealants.
