A dental sealant is a thin, plastic coating applied to the chewing surfaces of molars, premolars, and any deep lines (called pits and fissures) found on teeth. Notably, over 75% of dental cavities begin in these intricate grooves. Teeth with these characteristics are challenging to clean thoroughly and are highly vulnerable to decay. A sealant acts as a barrier, filling in these deep grooves and creating a smooth, easily cleanable surface.
Sealants can effectively protect teeth from decay for many years, although they require periodic checks for wear and chipping during routine dental visits.

Ideal Candidates for Dental Sealants:

Children and Adolescents: The prime time for sealants is as soon as the six-year molars (the first permanent back teeth) erupt or throughout the cavity-prone years of 6-16.
Adults: Adults with decay-free tooth surfaces that have deep grooves or depressions can also benefit from sealants.
Primary Teeth: Occasionally, sealants are considered for baby teeth with deep grooves or depressions, especially in children prone to cavities.

Understanding the Sealant Application Procedure

Applying sealants is a straightforward process performed by your dentist or dental hygienist, typically taking just a few minutes per tooth.

The teeth designated for sealant application are meticulously cleaned and then kept dry using cotton isolation. A special conditioning solution is applied to the enamel surface to enhance the bond between the sealant and the tooth. The teeth are then rinsed and thoroughly dried. The sealant material is carefully painted onto the enamel surface, ensuring complete coverage of the deep grooves or depressions. Depending on the type of sealant used, it will either harden naturally or using a special curing light.

Consistent home oral care, a balanced diet, and regular dental appointments will contribute to the longevity of your new dental sealants.
