The Meridian Tooth Chart is based on acupuncture meridians, pathways of energy that span across interrelated body parts, glands, and tissues. Each tooth is associated with a particular meridian, through which energy flows. Dentists familiar with the Meridian Tooth Chart are often able to assess patients’ general state of health and wellness simply through a review of the oral environment. If a weakness in a particular system or organ exists, the condition of the tooth associated with that area could exacerbate the problem.
