Simply stated, unhappy neck muscles can give rise to headaches, facial pain, jaw problems and tooth pain complaints even though the aching teeth are healthy. When it comes to facial pain, neck muscles may play an important role. Muscles in the neck support your head position and the posture of the lower jaw. Inflammation in the Temporomandibular Joints (TMJ’s) can cause the upper neck muscles to tighten. Eventually, this tightness can lead to the activation of muscle trigger points, which may in turn cause pain to the face, and limitation of jaw motion due to muscle contraction.
Neck pain can also be caused by persistent clenching or teeth grinding of the teeth at night. It has been shown that patients that use oral appliances at night clenching or grinding also experience a decrease in neck pain.
