齐国中大夫患有龋齿，淳于意用艾炷灸其左侧太阳脉（足太阳膀胱经在头面部的腧穴），并开具苦参汤，让他每日漱口三次，每次三升。经过五六天，病就好了。这是因为风邪侵袭，且睡觉时张口，进食后不漱口所致。（出自《史记》）
刘几年七十多岁，精神依然不衰。他每次饮酒后必定漱口，即使喝醉了也不忘记。他说这样可以避免牙齿疾病。他在傍晚时分吃少量食物，之后便已处理妥当。（出自《明道杂志》）
进士刘遁异遇到一个人说：世人养生往往本末倒置。早晚漱口，不如睡前漱口，以去除齿间积聚的食物残渣，牙齿也能坚固。现在的人吃冷物，一定要喝热汤来温暖脾胃，但这反而使脾胃受寒，又怎能起到温补作用呢？不如在吃冷物之前先喝热汤温热脾胃，接着再吃冷物，就不会有患病了。（出自《翰苑名谈》）
倪彦及朝奉曾任太原府幕僚，他说那里的人喜欢吃枣，无论贵贱老少，常把枣放在怀里或袖中，随手取出食用。因此郡里人的牙齿大多发黄，这是因为吃枣的缘故。正如嵇康所说：“齿居晋而黄，虱处头而黑。”（出自《遁斋闲览》）
西岳莲华峰碑上记载治疗口齿疾病及使胡须变黑的药歌：猪牙皂角、生姜、西国升麻、蜀地黄、木律（即胡黄连）、旱莲草、槐角子、细辛、荷叶（指剪去荷叶心部）。以上药材分量相当，与青盐等份一同烧制，研成细末使用效果更好。刷牙可使牙齿牢固，胡须鬓发变黑。谁知道世上还有这样的仙方呢？（出自《类苑》）
汪丞相徽之有一位受宠爱的门人，平时喜欢吃容易引发风邪的食物，尤其嗜好螃蟹。有时做成蟹包、蟹签，尽情食用。一天，他得了风热之疾，牙龈间肿起一块肉，逐渐增大堵塞口腔，导致嘴巴不能闭合，水浆无法入口，痛苦不堪，几乎丧命。有一位道士说能治此病，丞相请医生诊治，不久就好了。其方法是取生地黄汁一碗，猪牙皂角数条，在火上烤热，蘸取地黄汁直至吸尽，然后研末敷在肿起的肉上，随即消肿缩小。后来有人重金求取此方。（由其女婿李大夫讲述）
连续数月饮酒，导致咽喉溃烂、舌上生疮。用水煮螺蚌肉、葱、豉、姜、椒的汁液，饮用三盏，病愈。（出自《圣惠方》）
The Grand Master of Qi (Qizhong Dafu) suffered from dental caries. Chunyu Yi applied moxibustion to the left Taiyang vessel (Taiyang channel) and prescribed Kushen Tang (Sophora Root Decoction), instructing him to rinse his mouth three times daily with three sheng (approx. 600ml) per time. After five or six days, the illness was cured. This resulted from wind pathogen invasion and sleeping with an open mouth without rinsing after eating. (From *Records of the Grand Historian*)
Liu Ji was over seventy years old but remained vigorous in spirit. Every time he drank alcohol, he would rinse his mouth, never forgetting even when drunk. He said this practice could prevent dental diseases. He consumed a small amount of food in the late afternoon and then attended to it. (From *Mingdao Magazine*)
Jinshi Liu Dunyi encountered someone who said: People’s self-care is often misplaced. Rinsing the mouth morning and night is inferior to rinsing before bed to remove accumulated residue between teeth, thereby strengthening them. Nowadays, people eat cold foods and must drink hot soup to warm the spleen and stomach; however, this actually chills the spleen, making warming impossible. It is better to drink hot soup to warm the spleen before eating cold foods, so that consuming cold items will cause no harm. (From *Han Yuan Ming Tan*)
Ni Yanji, a Chaofeng official, once served as a staff officer in Taiyuan Prefecture. He stated that the locals loved eating dates, regardless of status or age, often keeping them in their bosoms or sleeves for easy access. Consequently, many people in the commandery had yellow teeth due to date consumption. As Ji Kang (Ji Shuye) said: "Teeth become yellow among the Jin people, just as lice turn black on the head." (From *Dun Zhai Xian Lan*)
The stele at Lianhua Peak of the Western Mountain records a medicinal verse for treating oral/dental issues and darkening facial hair: Zhu Ya Zao Jiao (Gleditsia Sinensis Fruit Spine), Sheng Jiang (Fresh Ginger), Xi Guo Sheng Ma (Cimicifuga Herba from the West), Shu Di Huang (Rehmanniae Radix Praeparata), Mu Lv (Picrorhizae Rhizoma), Han Lian Cao (Ecliptae Herba), Huai Jiao Zi (Sophorae Fructus), Xi Xin (Asari Radix et Rhizoma), and He Ye (Nelumbinis Folium - specifically the heart cut from the leaf). These herbs should be used in equal proportions, roasted together with Qing Yan (Halitum), ground into fine powder, and used for brushing teeth to firm them and darken beard and sideburns. Who knows such a celestial prescription exists in the world? (From *Lei Yuan*)
Wang Hui, a Chancellor, had a favored disciple who enjoyed eating foods that trigger wind pathogens, particularly crabs. He sometimes made crab dumplings or crab strips and ate them freely. One day, he contracted a wind-heat disorder. A fleshy swelling emerged between his teeth, gradually enlarging until it blocked his mouth, preventing closure and the intake of water or gruel. He suffered excruciating pain and was near death. A Daoist priest claimed he could cure this. The Chancellor summoned physicians, and he recovered quickly. The method involved taking one bowl of juice from fresh Shu Di Huang (Prepared Rehmannia Root), several pieces of Zhu Ya Zao Jiao (Gleditsia Sinensis Fruit Spine), heating them on fire until hot, dipping the spice into the juice until fully absorbed, grinding it into powder, and applying it to the swollen flesh. The swelling immediately subsided. Later, many offered gold to obtain this prescription. (Narrated by his son-in-law, Physician Li)
After drinking continuously for months, the throat became ulcerated and sores appeared on the tongue. Boil river snails, clams, scallions, fermented soybeans, ginger, and pepper in water, drink three cups of the decoction, and the illness will resolve. (From *Sheng Hui Fang*)
