What these registry facts mean
The NPI (National Provider Identifier) is the federal ID every HIPAA-covered provider uses to bill insurance. This NPI belongs to an organization, so it may cover several clinicians at this location. The specialty is the taxonomy the provider chose when registering; NPPES does not check it. A license number here is what the provider entered — confirm it with the state board before you rely on it. Periodontists specialize in the gums and bone that support the teeth, including placing implants, gum and bone grafting, and treating gum disease. Dentists who are not specialists can also place implants; the specialty here is the one the provider registered as primary.
Checking credentials: the specialty shown is the one this provider registered with the NPI system. Your state dental board's license lookup confirms the license, and the American Board of Prosthodontics, the American Board of Oral and Maxillofacial Surgery and the American Board of Periodontology each list their board-certified members.
