Dental Code D1351
Dental Code D1351 Description
Dental Code D1351 is a procedural code used in dental billing and insurance claims to describe the application of a dental sealant on a permanent tooth. Sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars to prevent cavities. The American Dental Association (ADA) categorizes D1351 under preventive dental services, emphasizing its role in reducing the risk of tooth decay.
This code is particularly important for pediatric and general dentistry, as sealants are highly effective in safeguarding teeth from bacteria and food particles that lead to cavities. Understanding D1351 is crucial for dental professionals, insurance providers, and patients seeking preventive care.

D1351 Dental Code Definition
According to the ADA Code on Dental Procedures and Nomenclature, D1351 is defined as:
“Sealant – per tooth: A resin material placed into the pits and fissures of caries-susceptible teeth to prevent decay.”
Key Features of D1351:
- Applies to permanent teeth only (sealants on primary teeth may use a different code).
- Covers one tooth per application (each tooth must be billed individually).
- Classified as a preventive measure, not restorative.
- Commonly used for molars and premolars, where decay is most likely.
When is D1351 Used?
- For children and teenagers as soon as permanent molars erupt (ages 6–14).
- For adults with deep fissures prone to cavities.
- As part of a comprehensive preventive dental plan.
