牙衄和牙宣，是指牙缝中出血的症状。如果是胃经实热所致，则血液涌出如注，口中必定有臭味且牙齿稳固不松动。适宜使用清胃汤治疗；病情严重的，可用调胃承气汤攻下。不如采用酒制大黄末三钱，用枳壳五钱煎成的汤液，加入少量童便调和服用，排出黑色粪便后即可痊愈。这是针对脉象洪大有力、阳明经热盛的情况。如果是胃经虚火所致，适宜使用二参汤，以及补中益气汤加黄连、丹皮。肾经虚弱者，血液点滴而出，牙齿悠悠然疼痛，口中无臭味但牙齿松动甚至脱落。治疗宜安补肾气，有火者用六味地黄丸，无火者用八味地黄丸，均加入猴姜（即骨碎补），随手见效。肝气盛者兼服芦荟丸。以上情况均可外用蒺藜汤、玄胡散、荔枝盐等药物，擦拭或漱口。
二参汤：治疗属于虚火引起的牙衄。
人参、玄参（各二钱，或五至七钱）
水煎后服用。
蒺藜汤：治疗牙衄，以及牙痛、牙龈根肿动摇者。
白蒺藜（一两，研为粗末）
用水两钟，煎至一钟，加入食盐一撮用于漱口。

玄胡索生研为末。用前述的蒺藜汤漱口腔后，将此药末敷于患处。
荔枝盐：治疗牙痛、牙宣，更能坚固牙齿、明目。
取一个荔枝，钻一个小孔，装入食盐七分、花椒三分，以填满为度。用纸包裹后用泥封固，在炭火中煅烧存性，研为细末。早晚用来擦牙。
补中益气汤、六味地黄丸、八味地黄丸（均见于溃疡章节）、芦荟丸（见疳疮门）。
攒齿疳，是指牙龈肉内长出骨尖，状如针刺，因而产生疼痛。小儿多见此症。用铍针刺开周围的肌肉，取出该处的牙齿。如果出血不止，用湿纸更换贴敷两次，出血自然停止。忌食浓烈滋腻的食物，牙齿日后会重新生长如初。
Tooth bleeding (Yan Nu) and gingival recession with bleeding (Ya Xuan) refer to bleeding from the interdental spaces. If caused by excess heat in the Stomach channel, blood flows out like a gush, accompanied by foul breath while the teeth remain firm. Qingwei Tang (Stomach-Clearing Decoction) is indicated; for severe cases, Tiaowei Chengqi Tang (Regulate the Stomach and Order the Qi Decoction) may be used to purge. Alternatively, one may use three qian of Rhizoma Rhei Preparatum (prepared with wine), mixed with a decoction of Fructus Aurantii (Zhi Ke, five qian) and a small amount of infant urine (Tong Bian), taken orally. Healing occurs after the passage of black stools. This method treats conditions characterized by a surging and forceful pulse, indicating excessive heat in the Yangming channel. If caused by deficiency fire in the Stomach channel,ershenshen Tang (Two-Shen Decoction) or Buzhong Yiqi Tang (Decoction for Reinforcing the Middle and Augmenting Qi) added with Radix Scutellariae (Huang Lian) and Cortex Moutan (Dan Pi) are indicated. In cases of Kidney channel deficiency, blood oozes drop by drop, accompanied by lingering pain in the teeth, without foul breath, but with loose or falling teeth. Treatment should focus on stabilizing the Kidneys. For those with fire, Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) is used; for those without fire, Shendi Dihuang Wan (Eight-Ingredient Pill with Rehmannia) is used. Both should be combined with Rhizoma Drynariae (Hou Jiang, also known as Gusuibu). These treatments yield immediate results. For those with excessive Liver qi, Lulu Wan (Aloe Pill) should be taken concurrently. Externally, Jili Tang (Tribulus Decoction), Xuanhu San (Cyperus Powder), and Lizhi Yan (Lychee Salt) can be applied for rubbing or rinsing.
Ershen Tang: Treats tooth bleeding due to deficiency fire.
Radix Ginseng (Renshen) and Radix Scrophulariae (Xuanshen) (each 2 qian, or 5–7 qian).
Decoct in water and take orally.
Jili Tang: Treats tooth bleeding, as well as toothache with swollen and mobile gingival roots.
Spina Tribuli (Bai Jili) (1 liang, ground into coarse powder).
Decoct in two zhong of water until one zhong remains. Add a pinch of salt and use for rinsing.
Xuanhu San: Treats Ya Xuan (gingival recession with bleeding).
Raw Rhizoma Cyperi Rotundi (Xuanhusuo) ground into powder. Rinse the mouth with the aforementioned Jili Tang, then apply this powder to the affected area.
Lizhi Yan: Treats toothache and Ya Xuan; further strengthens teeth and improves vision.
Take one Lychee fruit, pierce a hole, insert 0.7 fen of salt and 0.3 fen of Fructus Zanthoxyli (Huajiao), filling it completely. Wrap in paper, seal with mud, and calcine over charcoal fire until preserved in nature. Grind into powder. Rub onto teeth morning and evening.
Buzhong Yiqi Tang, Liuwei Dihuang Wan, Shendi Dihuang Wan (see Ulcer section), Lulu Wan (see Gan Chuang section).
Cuan Chi Gan refers to bone spicules protruding from within the gingival flesh, resembling needles, causing pain. This condition is common in children. Use a Bi needle to puncture the surrounding tissue, extract the involved tooth. If bleeding does not stop, apply wet paper patches, changing them twice, and the bleeding will cease naturally. Avoid rich and greasy foods. The tooth will regenerate as before.
