According to the National Institutes of Health Office of Dietary Supplements, magnesium is the fourth most abundant mineral in the body and is essential to good health. Approximately 50% of total body magnesium is found in bone. The other half is found predominantly inside cells of body tissues and organs. Only 1% of magnesium is found in blood, but the body works very hard to keep blood levels of magnesium constant. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis.
A 2008 study at Baylor University Medical Center looked at women with severe TMJ pain and noticed that 22% had a deficiency in magnesium. This study concluded that a poor diet and the inability to absorb nutrients contributed to the severity of the TMJ Disorder. Additionally, the University of Maryland Medical Center says calcium and magnesium supplements are often used to treat TMJ Disorders; however, their role is unknown since no scientific evidence exists.
At present, there is no widely accepted, standard diagnostic test to identify all TMJ Disorders (TMD). Because the causes and symptoms are not definitive, diagnosing TMD to the exclusion of other medical conditions can be problematic. Acknowledging this, patients should try to rule out other conditions that could be contributing to their symptoms. Magnesium deficiency is just one example of the kind of TMD misdiagnosis that can result. Read more about diagnostics and misdiagnosis.
