The Jaw – Spinal Cord Connection A Simple Check-up Can Make All the Difference in One’s Overall Health

A common question for dental practitioners concerns the need for a mouth guard for athletes. The simple answer is yes, but it is important to understand its function. A mouth guard is a covering that is placed on the upper or lower teeth to protect them from injury in sport-related activities.


A more thorough dental version of a mouth guard, known as an appliance, will also protect the temporomandibular joint (TMJ), from injury during periods of grinding and or clenching.

Over-the-counter mouth guards are manufactured predominantly in two premade forms that protect the teeth, but a custom appliance made at a dental office also maintains the balance between the upper and lower jaw so that dysfunction or destruction do not occur. Symptoms of imbalance include tooth pain, facial pain, headaches and neck pain. Using the latest technology, dentists have tools to identify many problems in the TMJ to make better diagnoses and appliances that prevent further damage to teeth and the TMJ joint.

The use of a dental appliance is important for the treatment of several jaw-related problems and appliances are also being used to address sleep apnea and snoring with great success. However, another aspect of a patient’s well-being is how the fit of that appliance affects the neurological flow of the entire body.

There are two parts to the jaw: the maxilla, which is the upper part of the skull, or the non-moveable part with teeth, and the mandible, or the moveable part with teeth. The connecting location is the TMJ. What holds these two parts together are the muscles and ligaments, which are all controlled by facial nerves that come from the brainstem and are connected to the first vertebrae (also called the atlas).

If the atlas is in alignment and the brainstem is firing its signals correctly, allowing the nerves to function as they should, an improperly set appliance will put pressure onto the nerves and actually be capable of taking the patient out of alignment at the atlas, causing the nerves to not fire correctly, and giving way to symptoms such as headaches, vertigo, TMJ issues and even low back pain.

A simple check can determine if the dental appliance is affecting the spinal alignment and nerve flow. If the nerves are not firing correctly, that is considered a misalignment. If it is determined that the mouth guard is causing a misalignment, having that appliance refit by a dentist that understands the jaw/ spinal cord connection and can work with your spinal health practitioner is key.

While mouth guards and dental appliances are valuable protective tools for a patient to continuously feel well, the combination of having a properly set dental appliance and staying in alignment is key.
