Tag: Jaw tension

As many as 1 in 8 adults experience jaw pain, grinding, or clenching, and research shows that certain nutritional deficiencies can contribute to the problem. Understanding what vitamins relax your jaw can provide a natural pathway to relieving this common and often frustrating tension.

According to a 2021 study in *BMC Oral Health*, sleep bruxism was significantly associated with vitamin D deficiency and low dietary calcium intake. This strong correlation suggests that a vitamin deficiency causes teeth clenching, highlighting the critical role nutrition plays in neuromuscular function and stress management.

According to the World Health Organization, up to 75% of the US population may not meet the recommended daily allowance for magnesium, a key mineral involved in muscle function and relaxation. This widespread shortfall is a major reason to investigate what deficiency causes jaw tension and other involuntary muscle contractions.
