What is an Orthodontist?

An orthodontist is a dentist, but your dentist might not be an orthodontist. Let us explain. Orthodontists like Dr. Carolyn Cronin and Dr. Scott Czarnik are specialists, while a dentist is a generalist. It’s similar to the medical world where you have general physicians and specialists like cardiologists and neurologists.

After receiving their doctorate from dental school, an orthodontist completes two to three additional years of speciality training in an orthodontic residency program. It’s there that they learn the intricacies of diagnosing, preventing and treating dental and facial irregularities using appliances, such as braces and Invisalign®.

Orthodontists spend a really, really long time in school. In fact, after high school, they hit the books for another 10 to 11 years! Once they receive their bachelor’s degree, they go on to attend four years of dental school where they obtain their Doctor of Dental Medicine (DMD) or Doctor of Dental Surgery (DDS) degree.


They must then be accepted into an orthodontic residency program (there are about 15 applicants for every opening!). During their residency, an orthodontist spends two to three years gaining extensive clinical experience, before becoming a certified specialist in orthodontics and dentofacial orthopedics.

Our Westminster, CO orthodontists, Dr. Cronin and Dr. Czarnik, are both certified by the American Board of Orthodontics (ABO). This means, after their residencies, they took the additional, voluntary step of completing hundreds of extra hours of preparation and education, as well as passing written and clinical examinations. They must renew their certification every 10 years.


According to the ABO, the credential demonstrates an orthodontist’s ability to provide the highest quality of patient care and represents their “personal and public commitment to the standard of speciality practice and life-long learning.”
