Can teeth pulled too far back be reversed?

Thankfully, yes. A lot of the orthodontic work I do in my office is for patients who are dissatisfied with their facial appearance after completion of orthodontics that involved over- retracting upper front teeth (usually associated with extracting bicuspid teeth prior to the original orthodontic work). The process involves wearing an adjustable "retainer-like" appliance that slowly redevelops the upper anterior jaw and pushing the upper front teeth back into a position where they can give appropriate upper lip and face support and allow the lower jaw to come forward to improve the facial profile. The treatment will also often involve uprighting posterior teeth to decrease the wrinkles in the corners of the mouth.Good luck!
