Is there any corrective treatment for my mishaps with dental braces?

Yes: Orthodontics is usually a smooth ride to a glorious smile; but even the best doctors run into trouble from time to time. Their colleagues in periodontics, restorative dentistry and maxillo-facial surgery can come to the team to help with any corrective measures that are needed to obtain the most ideal of results. It may not be a mishap, but an unforeseen complication that arises.

I hope it was : Specified what mishaps was experienced. Was there an unacceptable effect on your face, e.g., trauma, 4 bicuspid removal that resulted to narrow arches or flat lip that affected your profile, gum recession, brackets left for years that left decalcification for not seeing back the dentist..? All of these can be resolved or can get better...

Question unclear: By mishap do you mean damage to your braces, perhaps from sports trauma or damaging foods? Or do you mean an untoward reaction to treatment? Broken braces can and should be fixed asap to prevent incorrect movement. Unforeseen circumstance or reaction can be corrected or modified. See your orthodontist. With good communication all problems can be resolved.

Yes, but ...: Your question is a bit vague. Orthodontics can correct your bite and improve your smile. Would need to better understand "mishaps".

Almost always.: Braces are not a cure for malocclusion, but rather a treatment. Normally, orthodontic treatment reaches an acceptable and pleasing conclusion. However, some corrective treatments require additional adjunctive services such as periodontal or surgical correction, especially for cases with complicated or extenuating circumstances.
