Hi @young-friesen, thanks for your question. 

An orthodontist is a dentist that specialises orthodontic treatment, which is the correction of teeth and jaw misalignments using braces and clear aligners. They undergo additional specialty training in this area on top of their general dentist training. 

General dentists are also qualified to perform orthodontic treatment. However, complex cases may sometimes be referred to orthodontists for treatment due to their experience and expertise in this field. 

Ultimately, both general dentists and orthodontists are able to perform orthodontic treatment. Other factors you can consider in making your decision are: 
- costs
- level of experience

Hope this answers your question!
