Ever opened your jaw wide and heard it crack? Do you sometimes feel like when you bite your teeth together that one side touches before the other? These can indicate a misalignment of the jaw. Over time, a jaw misalignment can lead to degeneration of the jaw joint. A jaw misalignment can be due to injury, uneven fillings or crowns, or it can be due to bone misalignment in the neck. The top bone in the neck, called the Atlas or C1, sits right beside the jaw joint, or TMJ. Studies have shown that when the Atlas misaligns, it can affect how the TMJ moves. Studies have also shown that an Atlas adjustment can correct some TMJ issues. Visit a chiropractor to learn more.
