There are a number of different questions that I would like to ask you to find out more about whether there is actual pathology (i.e. a problem) with your TMJ (Temporo-Mandibular Joint), or if it is just an asymmetry. For instance, is there any pain (at rest, with chewing, etc) or is this just something that you noticed looking in the mirror?
To get these questions answered and establish a diagnosis, I would recommend making an appointment to have someone take a look at your jaw and examine the TMJs. An otolaryngologist
(ENT or Ear Nose Throat physician), OMFS (Oral Maxillo Facial Surgeon
), or dentist
would all be able to do a thorough exam of your TMJ(s) and answer all of your questions. There are definitely surgical procedures that can be performed on the TMJ, and there are also mandibular surgeries (the mandible is the lower law bone) that can be done for asymmetry if it is bad enough. However, if you have no pain and there isn't a problem with the actual mechanics of your joint, there is no guarantee that a surgery to alter your jaw might not affect function. These will all be things that they will need to discuss with you. I hope that this is helpful. Best of luck.
