The hook is also known as the temporomandibular joint, and if the hook falls out, it is important to go to the hospital as soon as possible to have it reset. A dropped hook is mainly an acute anterior dislocation of the temporomandibular joint, and if it occurs repeatedly, it may cause frequent dropped hooks. This disease must not be taken lightly and requires certain treatment measures. After resetting the hooks it is also necessary to apply local restrictions to the left and right hooks, such as wearing a bandage, which is mainly to relieve the acute inflammation and prevent permanent changes within the joint. After the joint has fallen out, it is important not to open the mouth too much, as it will gradually return to normal chewing and speaking function after a week or two, but it is important not to open the mouth too much.
