齿者，骨之余。骨不外露，齿质乃骨而外露，故曰余。如唇为肉余、爪为筋余、
发为血余，俱内藏者，余出而外露也。气则不言余，以气呼出可见耳。肾主骨，故

牙齿是骨骼的余气。骨骼不外露，牙齿本质上是骨却外露，所以称为“余”。如同嘴唇是肉的余气、指甲是筋的余气、头发是血的余气，都是内部藏蓄的部分，只有“余”才显露在外。至于气，则不称其为“余”，因为呼气时可见而已。肾主骨，所以牙齿归属于肾，这是指其根本。足阳明胃经进入上齿龈，手阳明大肠经进入下齿龈，这是指其经络联系。因此，本脏病变的多表现为齿骨疾病，经络病变的多表现为齿龈疾病。然而有虚实、风火、虫蚀等不同情况，需要仔细诊察加以区分，这样才能无不奏效。现选录方剂七首。

Teeth are the surplus of bone. Bone does not expose itself externally; teeth, being essentially bone, are exposed externally, hence termed "surplus." Similarly, lips are the surplus of flesh, nails are the surplus of sinews, and hair is the surplus of blood; these are internal stores, while only the "surplus" emerges and exposes itself. Qi is not referred to as surplus because exhaled air is visible. The Kidney governs bone, thus teeth belong to the Kidney, referring to their root. The Foot-Yangming Stomach Meridian enters the upper gum, and the Hand-Yangming Large Intestine Meridian enters the lower gum, referring to their meridians. Therefore, diseases originating from the Zang-Fu organs often affect the tooth bones, while meridian diseases often affect the gums. However, there are differences such as deficiency-excess, wind-fire, and worm erosion; careful diagnosis and differentiation ensure efficacy. Seven selected prescriptions follow.
