《经》曰∶丈夫八岁肾气实，齿更发长。盖以阴阳交与。阴气不胜其阳则成男，阴精
蕴蓄于内，阳中有阴，老阴之数，极于十，少阴之数次于八，男为少阳之气，其数当
七，而反八者，因阴蓄于中，故以少阴合之。少阴者，肾经也。肾主骨，遇八则少阴
之数正而肾气动，故男子八月而生齿，八岁而 ，明阴阳气和，乃能生成其形体也。又
曰∶“女子七岁，肾气盛，齿更发长”者，亦以阴阳交合，阳气不胜其阴而成女，阳精
蓄于内，阴中有阳，老阳之数极于九，少阳之数次于七，女为少阴之气而属于八，今以
少阳七数偶之者，亦以阳蓄于内，放至少阳之数，则内蓄之气始动而肾气盛，故女子七
月而生齿，七岁而 。有齿迟者，禀受肾气不足，而髓不强，齿为骨余，骨为肾余，骨
之所络而为髓，髓不足，故不能上充于齿而迟也。若能调养血气，固本复元，则齿自
生，而骨力坚凝矣。更有二三岁后，或乳食互进，或醉后房劳，乳儿致成肾疳，啼时满
口皆血，名曰宣露。或齿黑碎片，名曰崩砂。久则秽甚，牙根俱落，名曰腐龈。亦有
风热相搏，忿怒烦劳，其齿痛肿者，是手阳明足太阳之脉，系于齿，故牙根肿涌，名曰
龋齿。有喜嗜甘肥而生虫，即名虫齿。若跌扑所伤者，或急疳所坠者，则久落难生矣。

《黄帝内经》说：“男子到了八岁，肾气充实，牙齿更换，头发生长。”这是因为阴阳交合的缘故。阴气不能胜过阳气则生成男性，阴精蕴蓄于体内，阳中寓含阴，老阴的数极限为十，少阴的数次于八。男性属少阳之气，其数应当是七，但这里说是八，是因为阴蓄积于中，所以以少阴之数相合。少阴，就是肾经。肾主司骨骼，遇到八这个数时，少阴之数端正而肾气发动，所以男子在八个月大时长出乳牙，八岁时换牙，这说明阴阳之气调和，才能生成形体。又说：“女子到了七岁，肾气旺盛，牙齿更换，头发生长”，这也是因为阴阳交合，阳气不能胜过阴气而生成女性，阳精蓄积于内，阴中寓含阳，老阳的数极限为九，少阳的数次于七。女性属少阴之气而归属于八，现在用少阳七数与之配合，也是因为阳蓄积于内，直到少阳之数，内蓄之气才开始发动而肾气旺盛，所以女子在七个月大时长出乳牙，七岁时换牙。如果有牙齿发育迟缓的情况，是由于禀受先天肾气不足，导致骨髓不强健。齿为骨之余，骨为肾之余，骨所联络形成髓，如果髓不足，就不能向上充养牙齿，从而导致牙齿生长迟缓。如果能够调养气血，巩固根本恢复元气，那么牙齿自然生长，骨骼力量也会坚凝。另有两三岁以后，或者乳食交替不当，或者父亲醉酒后行房事哺乳婴儿，导致婴儿患上肾疳（因肾虚导致的疳积病证），啼哭时满口都是血，名叫宣露。或者牙齿发黑碎裂，名叫崩砂。时间久了秽气严重，牙根全部脱落，名叫腐龈。也有风热邪气相互搏结，加上愤怒烦劳，导致牙齿疼痛肿胀的，这是手阳明大肠经和足太阳膀胱经的经脉，联系于牙齿，所以牙根红肿涌起，名叫龋齿。有喜欢嗜好甘甜肥腻食物而生虫的，就名叫虫齿。如果是跌打损伤所致，或者被急疳坠落损伤的，那么牙齿长久脱落后就很难再长出来了。

The *Classic* states: "When a male reaches eight years old, his Kidney Qi becomes substantial, his teeth change, and his hair grows." This is due to the interaction of Yin and Yang. When Yin Qi cannot overcome Yang Qi, a male is formed; Yin essence accumulates internally, containing Yin within Yang. The number of Old Yin reaches its limit at ten, while the number of Young Yin follows at eight. Males possess the Qi of Young Yang, whose number should be seven, but here it is eight because Yin accumulates in the center, thus combining with the number of Young Yin. Young Yin refers to the Kidney Meridian. The Kidney governs bones. Upon reaching the number eight, the number of Young Yin becomes correct and Kidney Qi activates; therefore, males are born with deciduous teeth at eight months and undergo tooth replacement at eight years. This illustrates that the harmony of Yin and Yang Qi enables the formation of the physical body. It further states: "When a female reaches seven years old, her Kidney Qi flourishes, her teeth change, and her hair grows." This is also due to the union of Yin and Yang. When Yang Qi cannot overcome Yin Qi, a female is formed; Yang essence accumulates internally, containing Yang within Yin. The number of Old Yang reaches its limit at nine, while the number of Young Yang follows at seven. Females belong to the Qi of Young Yin and are associated with the number eight. The current pairing with the number seven of Young Yang is because Yang accumulates internally; only when the number of Young Yang is reached does the internally accumulated Qi begin to move and Kidney Qi flourish. Therefore, females are born with deciduous teeth at seven months and undergo tooth replacement at seven years.
If there is delayed dentition (Chi Chi), it is due to insufficient congenital Kidney Qi, resulting in weak marrow. Teeth are the surplus of bones, and bones are the surplus of the Kidneys. Marrow is formed by the connection of bones. If marrow is insufficient, it cannot nourish the teeth from above, leading to delayed eruption. If one can regulate Blood and Qi, consolidate the root, and restore vitality, the teeth will naturally grow, and bone strength will become firm.
Furthermore, after two or three years of age, improper alternating of milk and solid food, or paternal sexual activity while intoxicated during breastfeeding, may cause the infant to develop Shen Gan (Kidney deficiency-related malnutrition syndrome). Crying results in blood filling the mouth, named Xuanlu. Or teeth turn black and fragment, named Bengsha. Over time, the condition becomes foul, and all gum roots fall out, named Fugen. There are also cases where Wind-Heat pathogens struggle against each other, combined with anger and fatigue, causing tooth pain and swelling. This is because the Hand-Yangming Large Intestine Meridian and Foot-Taiyang Bladder Meridian connect to the teeth; thus, the gum roots swell and protrude, named Quchi (Cavities). Those who have a preference for sweet and fatty foods may develop worms in the teeth, named Chongchi. If caused by falls or blows, or damage from acute Gan syndromes, the teeth will not regrow after long-term loss.
