In answering this question it is necessary to define for you what medical malpractice is:"The definition of medical malpractice is an act or omission by a health care provider that deviates from what is the accepted standards of practice in the medical community. This act or omission then causes injury to the patient. Medical malpractice is basically professional negligence by a health care professional that leads to an injury or complications on the part of the patient."It appears that here that there may indeed be a question as to the standard of care that you received.  One would assume that your entire jaw would have been x-rayed for precautionary purposes but it is really difficult to determine in this forum.  Seek consultation from an attorney in your area.  The consultation should be free.  Good luck.
