The TMJ, also known as the ‘Temporomandibular Joint’, is the jaw joint that connects to your skull and allows you to open and close your mouth. During a car accident, the impact can cause increased tension through the joint and the muscles leading to pain. If you are chewing gum or possibly talking at the moment of impact, the force can shift your jaw and cause the joints to become misaligned leading to popping, clicking, or difficulties opening your mouth.  Common treatments for TMJ pain would be soft tissue work, acupuncture, joint mobilization, and laser therapy.  There are incidences where more specialized treatment needs to be done to get the best results.  Complex cases of TMJ are referred to a dentist where a custom TMJ splint will help with relieving pressure through the joint while sleeping, and/or botox injections will be recommended to decrease muscle tension
