Why might dental work come before braces?
Fixed braces make oral hygiene more demanding and apply controlled force to teeth and their supporting tissues. NHS guidance says teeth and gums need to be healthy before braces are fitted. Hospital orthodontic services similarly state that active decay and gum disease should be dealt with before treatment begins.
For adults, planning can also be more complex because existing crowns, root canals, missing teeth, implants, bridges or periodontal history may affect the sequence.
1. Dental check-up and professional cleaning
A recent dental examination helps identify untreated decay, gum inflammation, broken fillings and other problems before orthodontic appliances make access more difficult. Some adults also benefit from a professional cleaning or hygiene appointment before treatment starts.
2. Cavities, leaking fillings or unstable restorations
Active tooth decay generally needs to be treated before braces. A broken or unstable restoration may also need repair. The goal is not necessarily to replace every old filling, but to avoid beginning a long orthodontic course with a tooth that already needs active treatment.
3. Gum disease or significant inflammation
Active periodontal disease usually needs to be stabilized before orthodontic tooth movement. That can involve improved home care, professional periodontal treatment and reassessment. Adults with previous bone loss or recession may need closer periodontal monitoring throughout treatment.
4. Impacted teeth, missing teeth and restorative planning
An unerupted canine may require space creation and sometimes surgical exposure followed by orthodontic traction. Missing teeth can lead to two very different plans: orthodontically close the space or create/preserve space for a future replacement.
5. Palatal expansion in selected adults
If the upper jaw is narrow or there is a transverse bite problem, expansion may be part of the plan. Adult expansion is not simply the same procedure used in a growing child; the technique depends on skeletal maturity, anatomy and the amount of correction needed.
6. Root-canal treatment when a tooth is diseased
A tooth that needs endodontic treatment because of infection or pulpal disease may need to be stabilized before orthodontic movement. A previous root canal, however, does not automatically exclude a tooth from orthodontic treatment.
7. Jaw-surgery planning
Orthognathic surgery is a special case. It is often part of a combined pathway in which braces are placed before the operation, followed by surgery and then orthodontic finishing. So “jaw surgery before braces” is not the usual sequence in these pathways.
Who decides what happens first?
The orthodontist should coordinate the sequence with your general dentist and, where necessary, a periodontist, endodontist, oral surgeon or restorative dentist. Ask for a written or clearly explained sequence before treatment begins.
