Your case is a perfect example of why doctors who move teeth should NEVER do so until they understand completely what the ramifications will be on the patient's face, TMJ and airway. Beautiful straight teeth does not always result in a beautiful smile, beautiful face, healthy TMJ and patent airway. Based on what I can see from the limited photos provided, your original "buck teeth" problem was NOT the fault of your upper teeth but rather the fault of your lower jaw being too far back towards your neck. Had the original doctor repositioned the lower jaw forward and not removed upper teeth and retracted the upper front teeth then you would not be faced with the problems that you are describing. The good news is that much of what you don't like can be reversed. Unfortunately, it would be extremely difficult, if not impossible, to undo everything. What we do know is that your upper dental arch is too narrow; this is most likely the cause of your mandible never coming forward as it should have. Expanding your upper dental arch is easy to do with a simple, comfortable, removable appliance. We know that the lower jaw is too far back (just look at your profile). This too can be corrected with a simple, removable, comfortable appliance. What may be next to impossible to accomplish is repositioning completely forward the part of your upper dental arch that was retracted after teeth were removed. This can be somewhat corrected but very difficult to fully correct. Much of your "flat cheeks" can be corrected with upper arch development. Poor upper lip support can be improved with upper arch development. Airway and TMJ health can be substantially improved by upper arch development and moving the lower jaw forward. Unfortunately, you will have to redo the braces after the upper arch is developed and the lower jaw is moved forward; however, the benefits derived from this type of treatment are well worth it in terms of better facial aesthetics, improved profile and especially improved TMJ and airway health.In choosing a doctor, you need to ask questions about the relationship of tooth movement to TMJ and airway health. The doctor should be familiar with epigenetic orthodontics, neumopedics, orthotropics, functional orthopedics, and/or myofunctional orthodontics. Beware that MANY doctors will tell you that what I am describing is impossible to accomplish. I was also taught that it is impossible but I have since learned that it very much is possible and in fact I do it with my patients every day in practice. Good luck!
