New Jersey dental care and opinions wanted: Every morning my jaw is sore when I get up. It is stiff and will feel that way for about an hour each day. Lately I notice that when I chew or open my mouth to wide (like when I am yawing) I feel a popping or cracking in my jaw. I do not know if I just now noticing it or if this is something new. Either way if can not be too good right?
