手阳明大肠经的支脉进入牙齿。如果头面部受风邪侵袭，且阳明经脉正气虚弱，风邪便会乘虚顺着经脉流入牙齿，导致牙齿出现风邪症状，表现为轻微肿胀且牙根松动浮起。对于此类病症，使用汤药外敷、熨烫、针刺和砭石治疗的方法，另有专门的方剂。此处附上通过补益调养和导引宣发来治疗的方法。
《养生方·导引法》中说：凡是人经常感觉脊背僵硬强直且感到烦闷，不论什么季节，都可以进行以下练习：收缩咽喉并用力向两膊内收，仰面并将两膊向上努劲，头部向左右两侧扭转，左右各做二十一次（三七二十一），做完后停顿休息，等待气血运行平稳、气息安定之后，再继续下一次练习。动作开始时宜缓，后来可稍急，但绝不能先急后缓。如果没有患病，也建议在早晨起床时、中午时分、日落时分这三个时辰进行练习；如果用于治病，每个时辰分别做二十一次。此法可以祛除寒热病，以及脊部、腰部、头部、颈部、项部的疼痛，风痹症。口内生疮、牙齿受风、头晕目眩等症状，坚持练习最终都能彻底痊愈。

牙齿虫是指虫子啃食牙齿，又蛀蚀齿体，也会导致牙齿疼痛。都是因为牙齿根部有孔洞，虫子居住在内部，将牙齿吃尽后，又转移去蛀蚀其余的牙齿。
牙虫是虫子在牙齿中啃食，牙根有孔洞，虫子在其中活动，也会引起牙痛。吃掉一颗牙后，又转移去蛀蚀其他牙齿。

The branch of the Hand-Yangming Large Intestine Meridian (Shouyangming Dachang Jing) enters the teeth. If wind pathogen (Feng Xie) affects the head and face, and the Yangming meridian is deficient, the wind pathogen may follow the meridian into the teeth due to the deficiency. This causes wind in the teeth, manifesting as slight swelling and loose, floating tooth roots. For treating this condition with decoctions, external heat application (Wen), acupuncture, and bian stones, there are separate specific formulas. The methods of nourishing, supplementing, and guiding circulation (Dao Yin) are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Dao Yin Fa* (Guiding and Pulling Methods) states: Whenever a person feels stiffness and rigidity in the back accompanied by a sense of oppression, regardless of the season, they should perform the following: retract the throat and push inward toward both arms, extend the face upward while pushing the arms upward, and twist the head left and right. Perform this twenty-one times on each side (three sets of seven). Pause after each set, waiting for the blood circulation and qi movement to stabilize before proceeding. The movements should start slowly and become faster later; one must not start fast and then slow down. Even without illness, it is beneficial to practice at three specific times: upon waking in the morning, at noon, and at sunset. If used for therapeutic purposes, perform twenty-one repetitions at each time slot. This method can eliminate cold-heat disorders, pain in the spine, waist, head, neck, and nape, wind-bi syndrome, mouth sores, wind affecting the teeth, and dizziness. Persistent practice will ultimately resolve all these conditions.
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. When wind pathogen affects the head and face, the wind qi flows into the Yangming meridian and contends with the blood and qi between the gums, resulting in swelling.
The *Yangsheng Fang* states: Mercury should not come into contact with the teeth, as it causes gum swelling and predisposes one to tooth loss.
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. When wind pathogen affects the head and face, and the Yangming meridian is deficient, wind carrying heat enters the gums through the deficiency and contends with the blood, causing bleeding.
"Teeth worms" refer to insects that gnaw on the teeth and also eat into the dental structure, causing toothache. This occurs because there are holes at the root of the teeth where the insects reside inside, consuming the tooth entirely before moving on to infest other teeth.
"Dental worms" involve insects feeding within the teeth. With holes at the tooth root allowing insects to reside within, this also causes toothache. After consuming one tooth completely, they move to infest remaining teeth.
"Chew-tooth worms" involve insects gnawing on the teeth. With holes at the tooth root allowing insects to reside within, this also causes toothache. After consuming one tooth completely, they move to infest remaining teeth.
The *Yangsheng Fang* states: At cockcrow, frequently clench and tap the teeth thirty-six times. Long-term adherence prevents dental caries caused by insects and strengthens the teeth.
It further states: Before rising in the morning, rinse the mouth with saliva, swallow when the mouth is full, and then grind the teeth fourteen times (two sets of seven). Repeat this three times, then stop. This method is called "Refining Essence" (Lian Jing). It makes people vigorous and radiant in complexion, eliminates worms, and strengthens the teeth.
It also states: If one constantly consumes "Jade Spring," one will surely become vigorous and joyful in appearance, eliminating worms and strengthening the teeth. "Jade Spring" refers to the saliva in the mouth.
