[Hai Zang] If teeth or other areas suffer from dental caries that persist for years without healing, it should be treated as Yangming Blood Stasis Syndrome (Yangming Xuexu Zheng, a syndrome characterized by blood stasis in the Yangming channel). Use Tao Ren Cheng Qi Tang (Peach Kernel Decoction to Order the Qi) ground into fine powder, formed into pills with refined honey, sized like wutong seeds, and taken orally. Those who indulge in excessive alcohol consumption are prone to this disease; repeated administration is effective. (The formula for Tao Ren Cheng Qi Tang can be found in Shanghan Lun.)
[Dan Xi] To treat toothache caused by dental caries. Insert fine powder of Lili Rhizome (Lilu, *Veratrum nigrum*) into the cavity. Do not swallow saliva; the effect is miraculous. Another prescription: burn Jiang Zi (Jiangzi, *Croton tiglium*) over an oil lamp and fill it into the cavity.
[World Physicians] To treat swollen and painful dental caries. Take a piece of non-rotting Gleditsia Sinensis Fruit (Zaojiao, *Gleditsia sinensis*), remove the peel and seeds, then place one seed of Croton Tiglium Seed (Badou, *Croton tiglium*) at the position of the Gleditsia seed. Seal firmly with salt mud, burn to ash, and grind into fine powder. Use an ear-pick to scoop a small amount and fill it into the decayed tooth.
*[Waitai Mi Yao]* To treat toothache due to dental caries with worms. Take male sparrow feces, wrap in cotton, and insert into the cavity. Change once or twice daily; it is effective.
[Dan Xi] For dental caries. Use four fen of Aloe Vera (Luhui, *Aloe vera*), stir-fry and grind finely. First clean the teeth with salt, then apply a small amount. Another prescription: insert Aloe Vera and White Kolophony (Bai Jiaoxiang, *Pinus resinosa*) into the carious cavity. For dental caries, take pine resin sharp as a cone and insert it into the hole; after a short while, the worm will emerge onto the resin.
*[Bencao]* To treat toothache.
Artemisia Sieversiana Herb (Heshi, *Artemisia sieversiana*), Asarum Root (Xixin, *Asarum heterotropoides*), Angelica Dahurica Root (Baizhi, *Angelica dahurica*), Dried Eggplant (Qie, *Solanum melongena*) (equal parts).
Grind the above ingredients into powder. Apply a small amount to the painful area. If there is a cavity, form the powder into a pill with rice paste and insert it into the cavity; immediate relief is achieved.
[World Physicians] To treat toothache from dental caries. Insert Heshi branch into the affected area; immediate cure.

Grind finely. Apply a small amount to the diseased tooth.
[Dan Xi] When worms erode the gum causing rot. Burn a thorny needle to extract its exudate and apply it more than ten times. Alternatively, grind Realgar (Xionghuang, *Realgar*) into powder and apply; it cures the condition.
[Mei Shi] To treat unbearable pain from tooth-worms. Chew Frankincense (Xunluxiang, *Boswellia carterii*, similar to Ruxiang), swallow the juice; immediate recovery.
[Dan Xi] Another prescription for tooth-worm rot. Boil two hundred thorny needles in two sheng of water until reduced to one sheng. Hold in the mouth; excellent effect.
[Zhang Shi] To treat dental caries. Boil the white bark of Prunus Simonii Root (Yuligen Baipi, *Prunus simonii*) to make a concentrated decoction. Hold in the mouth and replace when cool; effective.
*[Shanju]* Dental caries. Rinse with warm rice vinegar; the worm will exit and heal spontaneously. Also, for wind-induced carious toothache. Decoct Fragrant Angelica Root (Xiang Baizhi, *Angelica dahurica*) and Asarum Root (Xixin, *Asarum heterotropoides*) to rinse the mouth. Additionally, burn Luffa Cylindrica Fruit (Sigua'er, *Luffa cylindrica*) to ash retaining its nature, and rub on the area.
*[Zhupu]* Toothache from worms. Tianxianzi (Hyoscyamus Niger Seed, *Hyoscyamus niger*), any quantity. Burn to produce smoke, use a bamboo tube to direct the smoke into the tooth; the worm dies and never recurs.
[World Physicians] To treat dental caries. Place a small tile with Jiuzi (Allium Tuberosum Seed, *Allium tuberosum*) mixed with oil, burn to produce smoke. Place over a bowl of water, cover with a funnel so the smoke enters the carious tooth through the funnel's opening. Worms resembling needles inside the tooth will fall into the water bowl; repeatedly effective.

Grind finely. Use half a zi per dose. First hold a mouthful of water aimed at the painful spot, inhale the powder through the nose, spit out the water, then use a finger dipped in a small amount of powder to rub the painful tooth. Also treats lateral and frontal headaches.
*[Jing]* To treat adults and children whose teeth have not grown for many years. Use thirty black soybeans, burn in cow dung fire until smoke ceases, grind finely, add a little Musk (Shexiang, *Moschus*), and mix evenly. First, prick the area where teeth are not growing with a needle to induce bleeding, then rub with a small amount of medicine. Avoid wind; avoid sour and salty foods.
