Zuanya Gan (Drilling Tooth Ulcer) arises at the gum root, where a hard, sharp, and pointed bone protrudes. The pain is intolerable, like needle pricks. This condition is caused by accumulated heat in the Liver and Stomach meridians.
[Note] This condition is caused by accumulated heat in the Liver and Stomach meridians. A bone tip drills out from within the flesh of the gum root like a thorn, causing extreme pain; it is common in children. The treatment method involves using a Pi Zhen (Bian Needle) to puncture the affected area, opening the flesh, and extracting the tooth along with its root. If bleeding does not stop, apply wet paper twice to stop it. Internally administer Lushui Xiaoguan Yin (Aloe Vera Decoction for Eliminating Gum Ulcers), and externally apply Bingpeng San (Ice and Borax Powder). Avoid rich flavors, and the tooth will regenerate as before.

Ya Ding (Toxic Carbuncle of the Tooth) forms in the dental gaps due to Stomach fire; damp-heat in the Large Intestine can also cause it. Swelling resembles millet grains and causes pain extending to the cheek. If accompanied by numbness and itching, it becomes Hei Ding (Black Carbuncle).
[Note] This condition is caused by Fire-Toxin in the Stomach meridian or Damp-Heat in the Large Intestine meridian. It usually appears in the lateral dental gaps, swelling into a grain-sized lump resembling millet, with pain radiating to the cheek and neck. If accompanied by numbness and itching, breaking open to bleed clear fluid, and causing extreme pain, it is called Hei Ding (Black Carbuncle), belonging to Kidney Fire-Toxin. All types should be punctured with the tip of a silver hairpin until blood appears. Apply Batuo San (Carbuncle Extraction Powder), then hold and slowly swallow Chansu Wan (Toad Venom Pill).
