Goals for Orthodontic Alignment
The objective is after orthodontic treatment is that the teeth are in ideal alignment, often times the edges of the teeth can have discrepancies that may need to be addressed by cosmetic adjustment of edges of the worn teeth. Rotations of teeth should be corrected with the clear braces. I suggest that your Dentist or Orthodontist answers any concerns you have before the completion of your orthodontic treatment.
Dissatisfied with results of your braces
If you're at the tail end of your treatment you've probably got a very good indication of what your teeth will look like once the braces come off and if things don't sit right with you and your dentist or orthodontist is not taking your concerns seriously it's wise to get a second opinion before those braces come off. Another dentist can make recommendations to help you get your smile where you want it to be. Good luck!
Express your concerns to your dentist / orthodontist before braces come off
Before your braces come off, I would express your concerns to your dentist or orthodontist. If your dentist or orthodontist does not answer your concerns, you could seek out a second opinion, preferably with an orthodontist.
