Temporomandibular joint disorder needs to pay attention to the following points in terms of diet: 1, avoid eating hard food (greater than the hardness of cooked peanut rice, should be regarded as hard food), chewing hard objects will cause greater pressure on the temporomandibular joint, and then cause joint damage; 2, correct the bite relationship, chew food bilaterally to avoid long-term unilateral chewing triggered by muscle imbalance, resulting in temporomandibular joint damage; 3, avoid excessive mouth opening; 4, avoid clenching too tightly, try to relax the muscles of the jaw joint.
