One of the biggest symptoms of a TMJ dislocation is jaw pain on one side of your face. You will find your temporomandibular joint at the ends of your jaw, just in front of your ear. When you open your mouth, the ball leaves the socket and comes forward. When you close your mouth, the ball goes back into the socket. A series of muscles, ligaments, and a cartilage disk hold your TMJ in place. Sometimes, the dislocation happens because of accident or injury.
However, if the ligaments in your jaw are too loose, they allow your mouth to open too wide. There are times that the joint will return to its place naturally. There is one huge signal that you have a dislocated jaw. Your jaw stays open despite your best efforts to close it. You may also experience a significant amount of pain. The maxilla, or upper part of the jaw, can also break. However, doctors typically consider these injuries to be facial fractures rather than a broken jaw.
Trauma to the face can also lead to a break or dislocation of the jaw. Which of these two injuries occurs depends on the location of the trauma and the degree of force. The trauma can have many different causes, such as from a fall or a sporting injury. A TMJ disorder causes pain and affects the movement of the jaw.
People with these disorders are at higher risk of dislocating their jaw. People who have dislocated their jaw before are also at a higher risk of jaw dislocation. A broken or dislocated jaw have similar symptoms. But there are some key differences. Facial trauma causing a broken jaw can also affect other areas of the face. For example, the injury can also damage the nose, mouth, or cheek.
This can cause further symptoms to occur. Broken and dislocated jaws often require immediate medical attention. It is essential to support the jaw until receiving medical help. This can be by manually holding the jaw in place or using a bandage around the head and under the jaw. Treating a broken jaw will depend on the severity of the injury. In fact, it accounts for nearly two-thirds of all jaw dislocations without trauma. The second most common cause of dislocating your jaw without trauma is yawning.
Other causes of jaw dislocation include dental procedures such as extractions, vomiting, and surgical procedures, especially those that involve intubation for general anesthesia. Sometimes, the use of the mouth as an entry point for endoscopic surgery can also cause dislocation of the jaw. Emergency symptoms include difficulty breathing or heavy bleeding. During work, sports, and recreation activities, using safety equipment, such as a helmet when playing football, or using mouth guards can prevent or minimize some injuries to the face or jaw.
