Orthodontists in Pennsylvania are licensed by the state dental board and registered with the federal National Provider Identifier (NPI) system under the orthodontics and dentofacial orthopedics specialty. This directory lists every active Pennsylvania practice carrying that specialty code.

The American Association of Orthodontists recommends a first orthodontic evaluation by age 7, and most practices offer that first consultation free. Adults make up a growing share of patients, and nearly every practice below treats both children and adults with braces or clear aligners.
