Whiplash : The sudden jolt from a rear-end collision can cause the head to snap back and forth. While whiplash primarily affects the neck, rapid movement can also lead to a strain or dislocaƟon of the TMJ. Bracing for Impact : Clenching the jaw Ɵghtly in anƟcipaƟon of a crash can put significant pressure on the TMJ, potenƟally causing injury. Symptoms and Effects of a TMJ Injury: Pain or Tenderness: Pain in the jaw, especially when chewing or speaking, is a common symptom. The pain may also extend to the ear, neck, or shoulders. Limited Jaw Movement: Difficulty or discomfort while opening or closing the mouth. Clicking or Popping Sounds: These sounds may be heard when the jaw moves, especially when chewing. It's worth noƟng that some people might have these sounds without pain or TMJ disorder. Locking of the Joint: The jaw may get stuck in an open or closed posiƟon temporarily. Changes in Bite : An individual might feel that their upper and lower teeth are not fiƫng together properly.
Swelling: The side of the face where the TMJ is located may become swollen. Headaches: TMJ issues can someƟmes cause tension headaches or even migraines.
