I injured my jaw about 3 months ago after I got caught with a hook. My jaw keeps clicking in and out of the joint near my ear when ever I open my mouth too much. I went to the Doctors and he basically said it is the joint slipping in and out of the socket but there is nothing he can do but I should consult my dentist. When I told my dentist they told me I need to see my Doctor so I just put up with it now but it is very annoying.
