Do you find that you frequently experience discomfort in your jaw? Or do you hear a popping or feel a clicking noise when you open your mouth, chew or speak? If so, you may be suffering from a common condition known as TMD, or temporomandibular joint disorder. TMD is an issue that can arise from the temporomandibular joint, which acts like a hinge connecting your skull to your jawbone. When it becomes damaged, it can lead to serious complications with your facial muscles, jaw, head, and neck.
