Due to over bite and TMJ, I had a lower jaw surgery 9 week ago to move my jaw forward.  I was wired shut for 4 weeks.  After that I wear rubber bands until now.  My problem is my jaws are now locked.  I cant open my mouth more than a width of my thumb, and my lower jaw only move up and down.  I can move my lower jaw side to side nor in and out.  Why my jaws are locked?What can I do to be able to open my mouth normal again?
Hello and welcome. Please do not get worried. This type of lock jaw is seen in many cases after a surgical procedure. You can keep exercising your jaw regularly. Keep chewing gums in your mouth and keep chewing them. This helps in two ways one is promoting excessive salivation and keeps your mouth infection free. Secondly exercising your muscles. You may also revisit your dentist and get a course of antibiotics prescribed for yourself. This would also be beneficial. Hope it helps. Thanks. Take care.
