Dentistry as a field of medicine splits into many different disciplines, each which can be studied and researched further at a higher level.
Orthodontics is one of these areas. Orthodontists have completed post-graduate qualifications in order to be registered by the General Dental Council as a specialist.
Dentists can have a special interest in orthodontics, which means they have experience in treating orthodontic cases, but it doesn’t mean that they are a specialist orthodontist.
Dentists can provide orthodontic treatment, but as orthodontists have completed more advanced training and have a more in-depth knowledge of the subject, they are better suited for carrying out more complex treatment.
