It is possible for the face to be deformed when the bones of the mouth are rattling when opened. If a patient has a rattling of bones during the opening of the mouth wide, it suggests that there may be a lesion of the temporomandibular joint on one or both sides. For example, if there is inflammation or subluxation of the temporomandibular joint, the patient will often have a larger temporomandibular joint on one side, and the bite muscle may become more inflated, and the bones on both sides of the nose may become asymmetrical. The effect of the above causes may lead to a slight deformation of the face in the future. It is recommended that patients with such symptoms should go to the dentistry department as soon as possible to clarify whether there is a TMJ lesion, and if so, to treat it in a timely manner. For example, physical therapy such as acupuncture and tui-na can be done for this area, and topical anti-inflammatory and pain-relieving medications such as Fotarine cream can be applied. During the treatment period, patients should not open their mouths wide and should not chew hard food.
