If you are prescribed wearing a night guard by your dentist, clench your jaw during the day, or find your jaw sore in the morning, this video will help you see the relationship between your posture and the jaw/teeth. It all boils down to your postural misalignment impacting your whole body including the neck!!
That is how the muscular imbalance due to issues that can be fully at a different location in your body, impacts how food is chewed and how the jaw endures more pressure on one side than the other.
Long term effect of this imbalance is jaw pain, headaches and need for night guard.
