Medical condition
Dislocation of jaw
Sagittal section of the articulation of the mandible.
Specialty
Emergency medicine
Dislocations occur when two bones that originally met at the joint detach.[1] Dislocations should not be confused with subluxation. Subluxation is when the joint is still partially attached to the bone.[2]
When a person has a dislocated jaw it is difficult to open and close the mouth.[3] Dislocation can occur following a series of events if the jaw locks while open or unable to close. If the jaw is dislocated, it may cause an extreme headache or inability to concentrate. When the muscle's alignment is out of sync, a pain will occur due to unwanted rotation of the jaw.[4]
If the pain remains constant, it may require surgery to realign the jaw.[5] Depending on the severity of the jaw's dislocation, pain relief such as paracetamol may assist to alleviate the initial chronic pain. If the pain relief is taken for an extended period of time, it may negatively affect the person while talking, eating, drinking, etc.
