*Waitai Miyao* and *Zhouhou Beiji Fang* use earthworm excrement, mixed with water to form pellets, burned until extremely red, then ground into a powder like flour. This is mixed with lard from the twelfth lunar month and applied to the gingiva (gums). Applied three times daily, it leads to recovery.
[Mao Xiansheng]'s prescription for treating pediatric periodontal disease (Ya Xuan) and bleeding from tooth gaps:
* Sophora root (*Sophorae Flavescentis Radix*) [Kushen], powdered, 1 liang;
* Alum (*Alumen*), calcined to ash, 1 qian.
Grind the above two ingredients into fine powder. Apply to the teeth and gums three times a day for immediate effect.
Zhang Rui's *Jifeng Fang* treats bleeding from between the teeth.
Take bitter bamboo leaves (*Bambusae Caulis Amarus*) in any quantity, decoct strongly in water to extract the juice. Add a small amount of salt. When the temperature is suitable (neither too hot nor too cold), hold in the mouth and spit out when it cools.
Another prescription: Take half a sheng of urine from a healthy young boy (Tongzi Xiaoye). Hold in the mouth in two or three portions, spitting out when it cools.
[Zhuang Shi]'s Shexiang San (Musk Powder): Treats pediatric halitosis (bad breath) and lip ulcers, along with gingival recession (gingiva exposure).
* Musk (*Moschus*);

* Aloe (*Aloe*);
* White Dragon Bone (*Os Draconis*), each 1 qian;
* Lead Monoxide (*Lithargyrum*), 2 qian;
* Melanterite (*Sideritis*), raw, half a liang;
* Dried Toad (*Bufo Viridis*), one piece (weighing half a liang), placed in a bottle and burned until only the carbonized residue remains (Cunxing).
Grind all ingredients together until extremely fine and uniform. First, wrap cotton around the tip of a chopstick, gently wash the area with a solution of salt and alum water, then apply the medicine.
*Qianjin Yifang*:
* Rehmannia Root (*Rehmanniae Radix Recens*);
* Angelica Pubescens Root (*Pubescent Angelicae Radix*), each 3 liang.
Chop the above two ingredients, soak in wine overnight, and hold in the mouth.
Another prescription: Frequently seal white salt powder onto the gingiva, three times during the day and twice at night.
Yet another prescription: Knock the teeth together three hundred times, morning and evening once each. This prevents recurrence for life, ensuring dental health even in old age.
Another prescription for loose teeth roots that are about to fall out:
Take a large piece of fresh Rehmannia Root (*Rehmanniae Radix Recens*), one cun long. Wrap it in cotton, place it against the teeth, chew to extract the juice, swallow the juice, and discard the residue when exhausted. Do this three times daily for recovery. Continue holding it for ten days to prevent recurrence.
Another prescription for swollen tooth roots:
* Pine Needles (*Pini Folium*), one handful;
* Salt (*Sal*), one he;
