What Is TMJ?
The Temporomandibular Joint (TMJ) is the small joint located in front of your ear where your skull and your lower jaw meet. The TMJ moves every time you talk, yawn, chew or swallow. It is one of the most frequently used joints in your body.
If you place your fingers in front of your ears, on the triangular structure in front of your ear, you can feel the joints on the left and right sides of your head. Move your finger just slightly forward and press firmly while you shift your jaw all the way open and shut. The motion you feel is in the TMJ.
