Why treat active cavities before braces?
Hospital orthodontic guidance commonly requires patients to be free of active decay before treatment begins. Brackets and wires add plaque-retentive areas, so an untreated cavity can become harder to monitor and restore later.
Do all old fillings need replacement?
No. A stable, healthy restoration can often remain. The dentist is looking for active problems: fracture, recurrent decay, poor margins, pain or another reason that the tooth is not stable.
What if a tooth has a crown?
Orthodontic treatment can often be performed on crowned teeth using appropriate bonding materials. The final restorative plan still matters, especially if the crown shape or position may need changing after tooth movement.
Some cosmetic restorative work is better after orthodontics
Replacing a visible crown, adding bonding or changing tooth shape may make more sense after the teeth are in their final orthodontic positions. This avoids designing an expensive restoration for a tooth position that is about to change.
What if a cavity appears during treatment?
Contact your dentist. Dental treatment is still possible with braces, although the orthodontist may occasionally need to remove or reposition a wire or bracket to give access.
Questions to ask
- Do I have any active decay?
- Are any fillings or crowns unstable?
- Should cosmetic restorations wait until after braces?
- Who coordinates access if dental work is needed during treatment?
