Disclaimer: These preliminary ‘Self Tests’ may help you understand that though pain can be a significant indicator, it is not the only signal for TMJ dysfunction. A final diagnosis will be required by a professional like Dr. Eddie Siman. If you feel severe pain or you know you cannot do some of these exercises please do not attempt them.
Moving your head
While watching in the mirror, try to touch your right ear to your right shoulder.
Now, repeat this in the other direction.
Next, try to turn your head so your chin is pointing to the right and then to the left.
If you have stiffness or pain, your bite could be the culprit.
Limited mobility is often a sign of muscle tension from an unbalanced bite. The same applies when you try looking up to the ceiling or down at your toes. Stiffness in the head and neck muscles mean that you may have a chronic condition that is bite-related.
You should be able to open your mouth more than 40 mm – measure from the tips of the upper teeth to the tips of the lower teeth. You can also measure this with your fingers. If you can fit 3 or more fingers between your teeth, you are opening your mouth normally. If, however you can only fit 2 fingers, your jaw’s mobility has been affected.
