Dental erosion, swelling, pain, and bleeding are all caused by Stomach Fire, though sometimes mixed pathogenic factors from various meridians and external causes are involved.

The *Yitong* states: The favored concubine of Prime Minister Wang of the Song Dynasty had a preference for rich and strong flavors. One day, intense Heat erupted, causing gum tissue to swell and protrude, gradually enlarging until the mouth could not close, preventing the intake of even liquids. A physician used one bowl of raw Shengdihuang juice (Rehmanniae Radix Recens Juice) and several pieces of Ya Zaojiao (Gleditsiae Sinensis Spina), heated them over fire, allowed the spines to absorb the juice completely, ground them into powder, and applied it to the swollen tissue. It subsided immediately, and she recovered within a few days.
