TMD occurs when your bite is not properly aligned. It can cause the jaw to experience unnatural stresses and prevent it from resting properly when your mouth is closed. If you have TMD, you may have noticed a clicking noise when you chew, speak, or yawn; you may even experience pain and discomfort during these actions. In some cases, your jaw may feel “locked” following a wide yawn.
TMD can cause pain and discomfort in the jaw as well as headaches that occur when the muscles that help the joints open and close become overtired. But beyond the pain and discomfort, TMD can also cause serious dental problems if left untreated.
