Did you know that TMJ (Temporomandibular joint dysfunction) can be caused by stress? When people are stressed or frustrated they tend to clench their teeth and flex the jawbone muscles. There are several symptoms that you should keep an eye out for including jaw pain, difficulty chewing, clicking, and locking of the jaw.  If you are suffering of any of these symptoms, we know how uncomfortable and in some cases very painful it can be.  Talk to your doctor at Hercules dental care to see what we can do to help.
