The movement of the temporomandibular joint is dependent on the cervicofacial muscles. It is the harmonious relationship between the contraction of some muscle chains and the relaxation of others, in an unconscious way, that enables us to speak, chew, yawn, etc ... Why do most patients who have TMJ changes also have problems with the cervical and facial muscles? The answer is simple: whenever we are contracting the chewing muscles excessively, we are also overloading the temporomandibular joint, thus causing great intra-articular stress. This stress can be so great that it moves the disc from its normal position to an abnormal position.
Stress and anxiety are phenomena that contribute to major muscular overload, especially in the cervical chains and masticatory muscles. Who hasn't already felt their teeth clenched and grinding against one another in times of stress? This constant clenching of teeth causes prolonged tensions in the muscles that end up having a negative effect, causing major muscle injuries. These muscle injuries are reflected in pain, muscle tiredness, tension headaches, and can even cause tinnitus in some patients. It is normal for patients to refer to a constant pounding, throbbing pain throughout the day in the masseter and temporal area.
