牙齿，是骨骼的终点，由骨髓滋养。另外，手阳明大肠经和足阳明胃经的支脉进入牙齿，因此，如果骨髓之气不足，或者阳明经脉虚弱，风冷之邪趁虚侵袭而导致疼痛的，称为风痛。如果有虫居住在齿根，不断侵蚀，并传染到其他牙齿引起疼痛的，称为虫痛。如果是足少阴肾经脉虚弱，不能荣养骨骼，因呼吸风寒，或饮用、咳嗽寒水而引发疼痛的，称为肾虚齿风痛。风痛的症状，多是牙龈肿胀，或者发红，遇到风则疼痛加剧。虫痛的症状，牙龈上有孔窍，严重时牙齿松动甚至暴露牙根。虚痛的症状，则是隐隐作痛，没有剧烈的疼痛，但病程长久不愈。也有因为肾虚导致阴火上冲而引起疼痛的，其表现为手脚发冷，腰膝酸软疼痛，气向上冲逆，头面部发热且面色发红，颈部筋脉粗大，舌头颜色不很红，牙龈不怎么肿胀，用七味汤加入骨碎补、牛膝治疗。服用一剂后效果如神。

Teeth are the terminal point of bones and are nourished by marrow. Additionally, the branch meridians of the Hand-Yangming Large Intestine Meridian and Foot-Yangming Stomach Meridian enter the teeth. Therefore, if the Qi of bone marrow is insufficient, or if the Yangming meridians are deficient, allowing Wind-Cold to invade and cause pain, it is termed Wind Toothache (Feng Tong). If parasites reside in the tooth roots, continuously eroding them and spreading to other teeth causing pain, it is termed Parasitic Toothache (Chong Tong). If the Foot-Shaoyin Kidney Meridian is deficient and cannot nourish the bones, leading to pain due to inhaling Wind-Cold or drinking/coughing up cold water, it is termed Kidney-Deficiency Wind Toothache (Shen Xu Chi Feng Tong). Symptoms of Wind Toothache include swollen gums, often red, with pain worsening upon exposure to wind. Symptoms of Parasitic Toothache include holes in the gums, and in severe cases, loose teeth or exposed roots. Symptoms of Deficiency Toothache involve lingering, mild discomfort without severe acute pain, yet persisting for a long time. There are also cases where Kidney Deficiency causes Yin Fire to flare upward, resulting in pain; manifestations include cold hands and feet, soreness and weakness in the lower back and knees, sensation of Qi rushing upward, heat and redness in the head and face, enlarged neck veins, a tongue that is not very red, and gums that are not significantly swollen. This is treated with Qiwei Tang (Seven-Ingredient Decoction) added with Gusuibu (Drynariae Rhizoma) and Niuxi (Achyranthis Bidentatae Radix). One dose yields miraculous results.
