Can TMJ Cause Lip Numbness
When you have a problem with your jaw called TMJ (temporomandibular joint disorder), it can sometimes cause numbness in your lips and other parts of your body. This might happen because the muscles in your face get tight and squeeze on other nerves, making them feel numb.
Usually, when your jaw puts pressure on a nerve called the trigeminal nerve, which helps you feel things on your face, you might feel numbness. This can make parts of your face, like your lips, feel like they have lost their feeling.
