                                While there is no single vitamin deficiency that directly causes teeth chattering or grinding (bruxism), research shows significant links between low nutrient levels and the condition. Involuntary muscle contractions and neurological signals, often exacerbated by stress, can trigger this jaw activity. Several key deficiencies, including magnesium and vitamin D, can disrupt these vital functions, contributing to bruxism.
