If your jaw clicks, locks, or feels sore in the morning, it could be a sign of TMD, which affects the jaw joint and chewing muscles. Common triggers include grinding your teeth at night, stress, or an uneven bite. You might also notice headaches or ear pressure. Try soft foods, warm compresses, and resting your jaw. If the pain keeps coming back, look into TMD Treatment New York City dentists offer, starting with a bite and joint exam. I dealt with the same locking. At Aesthetic & Implant Dental Arts, Dr. Joseph Maniscalco checked my bite and made a custom night guard. My TMJ Treatment New York City plan helped. Call +7187450179.
