Bruxism is not just a localized jaw problem, but a state of overstimulation of the central nervous system. Holistic medicine looks for systemic triggers behind this uncontrollable teeth grinding at night. Chief among these is “Heavy Metal Toxicity,” caused by substances like lead, mercury, and aluminum; these metals accumulate in brain tissue, disrupting nerve transmission and leading to involuntary muscle contractions (spasms). A second common cause is “Intestinal Parasites” (especially pinworms). The toxins secreted by these parasites at night stimulate the vagus nerve via the gut-brain axis, triggering the autonomic nervous system and causing severe bruxism attacks during sleep. Holistic treatment involves night guards, stool and hair analyses, parasite elimination, and heavy metal chelation (detoxification) protocols.
