Alzheimer's Linked to Dental Fillings

Alzheimer’s Linked to Dental Fillings Your dentist may be planting the seeds of Alzheimer’s Disease with every filling. Research conducted at the University of Calgary Faculty of Medicine has demonstrated that trace amounts of mercury can cause a type of nerve damage found in the victims of Alzheimer’s Disease. The level of mercury exposure used by the researchers is consistent with levels found in humans with mercury/silver amalgam dental fillings. The exposure to mercury caused the formation of “neurofibrillar tangles,†which are one of the two diagnostic markers for Alzheimer’s Disease. In their research, published in March 2001 in the peer-reviewed journal NeuroReport, the scientists found that other metals, including aluminum, did not cause the damage. Previous research has shown that mercury can also cause the formation of the other Alzheimer’s marker, “amyloid plaques.†(International Academy of Oral Medicine and Toxicology, www.iaomt.org)
