论曰，牙齿不生者，由风疳齿龋诸疾，遂致脱落，久而不生也，夫肾主骨，齿者骨之所
终，髓之所养也，凡人血气强盛，骨髓坚固，齿虽脱落，则必复生，若血气衰微，骨髓虚弱
，则齿不能更生也，内经谓男子八岁，肾气盛，齿更发长，至于八八，则齿发去是也，治法
宜填骨髓，养肾气，则齿可复生也。

论述说，牙齿不生长，是由于风疳、齿龋等各种疾病，导致牙齿脱落，时间久了就不再生长。肾主司骨骼，牙齿是骨骼的终点（即骨骼的外在表现），由骨髓滋养。凡是人体气血强盛，骨髓坚固，牙齿即使脱落，也必定会重新生长；如果气血衰微，骨髓虚弱，那么牙齿就不能再生长了。《内经》中说男子八岁时，肾气旺盛，牙齿更换、头发变长，到了六十四岁（八八之年），则牙齿和头发脱落，说的就是这个道理。治疗方法应当填补骨髓，滋养肾气，这样牙齿就可以重新生长。

It is stated that the failure of teeth to grow is caused by various diseases such as wind-related caries (wind-gum disease) and dental caries, leading to tooth loss, after which they fail to regrow over time. The Kidney governs bones; teeth are the culmination of bones and are nourished by marrow. When a person's Qi and Blood are strong and marrow is solid, even if teeth fall out, they will certainly regrow. However, if Qi and Blood are weak and marrow is deficient, teeth cannot regenerate. The *Neijing* states that at age eight, men experience an abundance of Kidney Qi, resulting in the replacement of teeth and growth of hair; by age sixty-four (eight times eight), teeth and hair fall out. This refers to the aforementioned phenomenon. The treatment method should focus on filling the marrow and nourishing Kidney Qi, so that teeth may regrow.
