The lower teeth are part of the Hand Yangming Large Intestine Meridian, so as an adjunctive treatment, acupuncture can be performed on points of the Hand Yangming Large Intestine Meridian, such as Hegu, Shangyang, Ermai, and Sanmai. The meridians have a distant healing effect, and the lower teeth are on the part passed by the circulation of the Hand Yangming Large Intestine Meridian, so the acupuncture points on the Hand Yangming Large Intestine Meridian can treat lower toothache. This is an application of acupuncture where the meridian passes through and where the main treatment goes. Hegu is located at the midpoint of the radial side of the second metacarpophalangeal joint. Shang Yang is located on the radial side of the end joint of the index finger. Erma point is located at the distal red and white meatus of the radial side of the second metacarpophalangeal joint. Sanma point is located in the proximal depression of the radial side of the second metacarpophalangeal joint. If you need to receive acupuncture-assisted treatment, you need to be operated by a professional practitioner.
