What Are Dental Sealants?

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

Sealants can provide long-lasting protection against decay for many years, but it’s important to have them checked for wear and chipping during regular dental visits.

Who Can Benefit from Sealants?

  • Children and Teenagers: As soon as the six-year molars (the first permanent back teeth) emerge, or anytime during the cavity-prone years of ages 6-16.
  • Adults: For tooth surfaces without decay that have deep grooves or depressions.
  • Baby Teeth: Occasionally applied if a child has deep grooves and is cavity-prone.

How Are Sealants Applied?

The application of sealants is quick and straightforward, typically taking just a few minutes per tooth.

  1. Cleaning: The teeth to be sealed are thoroughly cleaned.
  2. Isolation: Cotton is placed around the teeth to keep the area dry.
  3. Bonding Solution: A special solution is applied to the enamel to help the sealant bond effectively.
  4. Rinsing and Drying: The teeth are then rinsed and dried.
  5. Sealant Application: The sealant material is carefully painted onto the enamel surface to cover the deep grooves. Depending on the type of sealant used, it will either harden on its own or be set with a special curing light.

To maximize the effectiveness of sealants, maintain proper home care, enjoy a balanced diet, and attend regular dental check-ups.
