closes jaw
Opens and closes your lower jaw
There are three muscles that control the jaw. One on each side of your neck, you can feel them. Also there are two more matter of fact in the back of your head. The first one is at the bottom of your brain stem, and it connects to the first bone in your spine. The second one is attached to your brain stem as well, and is connected to the bone in your spine where your bra strap ends. When the jaw locks, it is sometimes caused by these muscles and a disc on each side of your jaw in a specific socket, that are often irritated by stress. For more information about how to stop the locking of a jaw, set an appointment with Dr. Paul H. Rigali. He has offices in Wallingford next to IParty and one in Meriden I am not sure of the location. He is a very helpful Orthodontics professional and has helped me along with several other people with the causes of locked jaws. Every person is different so where you have pain may be different than where I did.
