论述说：牙齿是肾脏的外在表现，口腔是脾脏的孔窍。多条经络都汇聚于口腔，其中牙齿是手阳明和足阳明经脉所经过的地方。上牙龈归属于坤土（即脾胃），是足阳明胃经贯穿络属的部位，其特性是静止不动；下牙龈咀嚼食物时运动不止，是手阳明大肠经贯穿络属的部位。手阳明大肠经厌恶寒冷饮食而喜欢温热饮食，足阳明胃经则喜欢寒冷饮食而厌恶温热饮食。它们的病症各不相同。牙齿作为肾脏的外在表现，也喜好寒冷，因为寒冷能使牙齿坚固牢靠。由于致病原因不同，治疗方法也不同。有的因厌恶热邪而疼痛，有的因厌恶寒邪而疼痛，有的既厌恶寒邪又厌恶热邪而疼痛，有的因厌恶寒邪但饮用少量热水或多量热水而疼痛，有的因厌恶热邪但饮用少量冷水或多量冷水而疼痛，有的因牙齿动摇而疼痛，有的因牙龈肿胀隆起而疼痛，有的因脾胃中有风邪，仅感觉有风侵袭而疼痛，还有的是因为牙齿多被虫蛀蚀，导致牙齿缺损、颜色改变，这是虫牙痛；有的是因为胃中气虚，不能抵御寒冷暴露于外的牙齿而疼痛；有的是牙齿疼痛且伴有不可接近的秽臭气味。疼痛既然有多种不同情况，怎么可以用一种药物来治疗所有情况呢？
治疗客寒侵犯脑部，风寒湿邪导致的脑痛、项部筋脉拘急、牙齿动摇、肉龈萎缩脱落及疼痛。

Translation:
It is stated that teeth are the external manifestation of the Kidney (Shen), and the mouth is the orifice of the Spleen (Pi). Many meridians converge in the mouth. The teeth are traversed by the Hand-Yangming and Foot-Yangming meridians. The upper gums belong to Kun Earth (referring to the Spleen and Stomach) and are connected by the Foot-Yangming Stomach Meridian; their characteristic is stillness and immobility. The lower gums move ceaselessly during chewing and are connected by the Hand-Yangming Large Intestine Meridian. The Hand-Yangming meridian dislikes cold drinks and prefers heat, whereas the Foot-Yangming meridian prefers cold drinks and dislikes heat. Their pathologies vary. As the external manifestation of the Kidney, teeth also favor cold, as cold ensures firmness and stability. Due to differing pathological causes, treatments differ. Some suffer pain due to aversion to heat; some due to aversion to cold; some due to aversion to both cold and heat; some due to aversion to cold but drinking small amounts of hot water or large amounts of hot water; some due to aversion to heat but drinking small amounts of cold water or large amounts of cold water; some due to tooth mobility; some due to swollen and protruding gums; some due to Wind-Evil in the Spleen and Stomach, feeling only wind-induced pain; others have teeth eroded by worms, resulting in missing teeth and color changes, known as worm-toothache; some have pain because Qi deficiency in the Stomach fails to protect exposed teeth from cold; some have painful teeth accompanied by foul odor that is unbearable. Since pains vary so much, how can a single medicine treat all cases?
