Oral and Maxillofacial Surgery (Dentist): how many are there, and how many are in private practice?

National totals

What this specialty covers

The specialty of dentistry which includes the diagnosis, surgical and adjunctive treatment of diseases, injuries and defects involving both the functional and esthetic aspects of the hard and soft tissues of the oral and maxillofacial region.

Reading the sole-proprietor share

For this specialty, the sole-proprietor share identifies records whose NPPES sole-proprietor field is flagged, which can help describe organizational status but is not a count of dentists working in private practice. The field is self-reported and may not capture group-practice arrangements, ownership structures, or other practice models, so the share is an imperfect proxy for private practice.

By state

New NPI registrations by year

Counts reflect the year each NPI was first issued, among records still active today. The final year is partial: this data covers through 2026-01-11.

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• The count covers active NPI records with this taxonomy as the primary classification, so it does not equal every clinician or practice providing these services.
• State totals depend on NPPES address information and do not show where all services are delivered.
• Providers are counted once, by their primary taxonomy code only.
