这种病症多见于小儿。取活蚬子三四个，撬开取出肉，先将壳烧成枯炭，与蚬肉一起捣烂敷在患处，效果很好。
直接取睡觉的席子底下的灰尘一捻，放入口中，不要让本人知道。这样就能痊愈。
牙齿不宜轻易拔除，拔除后满口牙齿都会松动。只有在实在痛得厉害，影响饮食时，才可以拔除，否则不拔为好。用大鲫鱼一条（约重十两），放入白信石一钱，塞入鱼腹内缝合鱼口，挂在有风但晒不到太阳、猫鼠够不到的地方阴干，七天后鱼鳞翘起，具有定痛作用。
另一个方子：用大蒜一个捣烂，加入白龙骨末一、二分，拌匀后贴在疼痛处，半小时后即可脱落。
炉甘石（研细）、石膏各等分，每天擦拭牙齿，不要刷牙震动，久了牙齿自然紧密。
用盐梅擦牙，唾液流出后牙齿就张开，这个方法最妙。或者用瓷调羹撬开也可以，千万不能用铜铁工具撬动，如果实在张不开，可以用物打断一颗牙，以便灌药。
前面提到的骨碎补一方，效果很好。治疗牙痛的方药很多，临时见效的很少，即使有轻微疗效，也难免再次疼痛。我自从十岁以后，多次患此症，每次发作必持续数日，疼痛严重到不能饮食，甚至出现寒热交替的症状，医药都不见效。后来得到一种方法，平时小便时咬紧牙关，就永远没有这个祸患了。按照这个方法坚持一年之内，偶尔发作几次，时间久了就不再复发，其妙无穷。另外饭后漱口，晚间洗牙，也是好方法。
又一个方子：凡是人到中年及将老时，牙齿多会脱落，或松动而不立即脱落，更为不便。务必记住刚掉牙时，将快要脱落的牙齿放在瓦片上用火焙干研成细粉，敷在满口牙齿上，半天后脱落，再吞服下去，可以保住剩余的牙齿永不脱落。
This condition is common in children. Take three or four live clams (Corbicula), pry them open to extract the meat, first calcine the shells until charred, then pound the shells and clam meat together into a paste and apply it to the affected area; this is very effective.
Simply take a pinch of dust from under the sleeping mat, place it in the mouth, without letting the patient know. This will lead to immediate recovery.
For those who have consumed too much sour food, eating walnut kernels (Juglandis Semen) will cure it immediately.
Teeth should not be extracted casually; extraction causes all teeth in the mouth to become loose. Extraction is only permissible when the pain is extreme and interferes with eating; otherwise, it is best not to extract. Use one large crucian carp (Cyprinus carpio var. orientalis) (weighing about 10 liang), insert one qian of white arsenic (Realgar and Orpiment mixture, specifically Realgar/Orpiment refined as Baixinshi) into its abdomen, sew the wound shut, and hang it in a ventilated but shaded place where cats and mice cannot reach. Dry it in the shade for seven days until the scales rise; this preparation has an analgesic effect.
Another prescription: Pound one garlic bulb (Allii Sativi Bulbus) into a paste, mix with one to two fen of powdered dragon bone (Fossilia Ossis Mastodi), apply evenly to the painful area, and the tooth will fall out within half an hour.
Equal parts of calamine (Calamina) (finely ground) and gypsum (Gypsum Fibrosum) are used to rub the teeth daily. Do not brush vigorously; over time, the teeth will naturally become tight.
Rubbing salted plum (Prunus mume fructus salificatus) on the teeth induces salivation, which opens the jaw; this method is excellent. Alternatively, use a porcelain spoon to pry it open. Do not use copper or iron tools to pry, as this may damage the teeth. If the mouth cannot be opened, breaking one tooth with an object may allow for medication administration.
Teeth falling out and regrowing (see the subsequent formula Gu Chi Shu Gu San for fixing teeth).
The previously mentioned formula containing Duan Gu Bu (Drynariae Rhizoma) is very effective. There are many prescriptions for toothache, but few provide immediate relief. Even if there is slight efficacy, recurrence of pain is inevitable. Since the age of ten, I have suffered from this condition repeatedly. Each episode lasted several days, with severe pain preventing eating, and even alternating chills and fever, rendering medical treatments ineffective. Later, I discovered a method: tightly clenched the teeth during urination. Following this practice, the problem never recurred. Adhering to this method for one year resulted in only occasional minor episodes, and eventually, no further recurrences occurred; its efficacy is profound. Additionally, rinsing the mouth after meals and washing the teeth at night are also good methods.
Another prescription: For people in middle age or approaching old age, teeth often fall out or become loose without falling out immediately, causing inconvenience. Remember when a tooth is about to fall out: place the impending tooth on a tile and bake it dry over fire until charred, then grind it into fine powder. Apply this powder to all the teeth. After half a day, the loose teeth will fall out. Swallow the powder to ensure the remaining teeth never fall out.
Another prescription: Rhubarb (Rhei Radix et Rhizoma) 5 qian, Sweet Scilla (Gansong), Cyperus rotundus rhizome (Xiangfu) (cleaned of hairs, processed with wine), Angelica dahurica root (Baizhi), and raw Gypsum (Gypsum Fibrosum) each 5 qian, true Sichuan pepper (Zanthoxyli Pericarpium) (for those with stomach cold... rub
