口和牙齿，是脏腑的门户，呼吸的枢纽。它们摄取滋味以充实胃肠，流通津液以滋润经脉。因此，口是脾的外在征候，牙齿是骨骼荣华的表现，对于全身健康来说至关重要。所以《黄庭经》说：口是玉池，太和宫，通过漱口吞咽灵液，可以避免灾祸蔓延，损伤腐朽更加严重。又经典说：嘴唇是飞门，牙齿是户门，应当发出五音，抵御各种邪气。凡是疾病的发生，多由口而入。含着恶风吞咽津液，使痰饮停滞在膈部，导致心胸壅滞，毒瓦斯攻冲蒸灼，时间久了熏染，怎么能不造成损害？
探究疾病的根本，确实有多种情况。比如疳蚀病，其齿龈虚软但没有脓血；另一种称为“䶦”（chī）的病，其齿牙龈触碰到就会流出脓血；还有口疳，其牙龈不触碰也自然流出脓血；又有风疳，其上牙龈牙齿上方有小孔，形状像蜂窝；又有齿疳，其齿骨脆弱腐烂；又有齿龈、唇口突然变成白色或青黑色的，这是急疳的症状，死亡不超过十天，必须紧急治疗。先看嘴唇和脸颊内部，如果有紫红色或青黑色的脉络处，就必须用针刺破放出恶血，否则用火烙也可以。如果牙齿上附有黄黑色的物体，形状像烂骨头一样，各自呈现齿状，凡治疗牙齿疾病的人，先看是否有这种物体，就必须用疳刀刮除。如果牙齿上附有像蝉翼一样的东西，或者像鸡蛋膜一样的东西，或者像丝线缠绕着牙根的东西，也必须用疳刀刮除。如果不这样做，那么齿牙龈就永远不会附着在牙根上了。
至于牙齿疼痛，是牙根牵引作痛。牙齿是骨骼的余气，由骨髓滋养。手阳明大肠经的支脉进入牙齿。如果髓气不足……

The mouth and teeth are the gates of the zang-fu organs and the pivot of respiration. They receive flavors to nourish the stomach and intestines, and circulate body fluids to moisten the meridians. Therefore, the mouth is the external manifestation of the Spleen (Pi), and the teeth represent the flourishing state of the bones. This is of great importance to the whole body. Thus, the *Huangting Jing* (Yellow Court Classic) states: "The mouth is the Jade Pool, the Palace of Great Harmony; by rinsing and swallowing the spiritual fluid, disasters will not spread, and decay will be prevented." Furthermore, classics state: "The lips are the Flying Gate, the teeth are the Household Gate," and one should articulate the five tones to subdue various pathogens. All diseases originate from the mouth. Inhaling evil wind while swallowing saliva causes phlegm-fluids to stagnate in the diaphragm, leading to chest and heart congestion, with toxic vapors attacking and steaming internally. Over time, this薰 (xūn - fumes/steams) causes damage.
Investigating the root of these diseases reveals many types. For instance, in *gan* (canker/gum disease), the gums are soft and flaccid without pus or blood. Another condition called *chi* (gum erosion), when touching the gums, causes pus and blood to flow out. In oral *gan*, the gums bleed spontaneously without being touched. In wind-induced *gan*, there are small holes above the upper gums resembling a honeycomb. In tooth *gan*, the tooth bone becomes brittle and rotten. If the gums, lips, and mouth suddenly turn white or cyan-black, it indicates acute *gan*, which can lead to death within ten days if not treated urgently. First, examine the inner lips and cheeks for purple-red or cyan-black vessels; puncture them with needles to release evil blood, or cauterize them if necessary. If yellow-black substances resembling rotten bone appear attached to the teeth, each shaped like a tooth, they must be scraped off using a *gan* knife. Similarly, substances resembling cicada wings, egg membranes, or silk threads缠绕 (winding around) the tooth roots must also be removed with the *gan* knife. Otherwise, the gums will never adhere to the tooth roots again.
Regarding toothache, it is pain radiating from the tooth root. Teeth are the surplus of bones, nourished by marrow. The branch meridian of the Hand-Yangming Large Intestine Meridian enters the teeth. If the marrow qi is deficient...
