手阳明之支脉入于齿，足阳明脉有入于颊，遍于齿者。其经虚，风气客之，结搏齿间，
与血气相乘，则龈肿。热气加之，脓汁出而臭，侵食齿龈，谓之龋齿，亦曰风龋。
《养生方》云∶朝夕琢齿，齿不龋。
又云∶食毕，常漱口数过。不尔，使人病龋齿。
齿 者，是虫食齿至龈，脓烂汁臭，如蚀之状，故谓之齿 。
手阳明之支脉入于齿。头面有风冷，传入其脉，令齿龈间津液化为脓汁，血气虚
竭，不能荣于齿，故齿根露而挺出。
手阳明之支脉入于齿，足阳明之脉又遍于齿，齿为骨之所终，髓之所养。经脉虚，风邪
乘之，血气不能荣润，故令动摇。
齿牙皆是骨之所终，髓之所养，手阳明、足阳明之脉，并入于齿。若血气充实，则骨髓
强盛，其齿损落，犹能更生；若血气虚耗，风冷乘之，致令齿或龋或龈落者，不能复生。
齿音离者，是风冷客于齿龈间，令齿龈落而脓出，其齿则疏，语则齿间有风过
之声，世谓之齿音离也。
牙齿皆是骨之所终，髓之所养也。手阳明、足阳明之脉，皆入于齿。风冷乘其经脉，则
髓骨血损，不能荣润于牙齿，故令牙齿黯黑，谓之历蠹。
手阳明之支脉入于齿。风邪客于经脉，流滞齿根，使龈肿脓汁出，愈而更发，谓之
齿者，骨之所终，髓之所养。髓弱骨虚，风气客之，则齿 。
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth, and the Foot-Yangming Stomach Meridian has branches entering the cheeks and covering the teeth. If the meridians are deficient, wind pathogen invades, condensing and obstructing between the teeth, interacting with blood and qi, resulting in gingival swelling. If heat pathogen is added, pus flows out with a foul odor, eroding the teeth and gums; this is called dental caries (caries dentis), also known as wind caries.
The *Yangsheng Fang* states: Grinding the teeth morning and evening prevents dental caries.
It also states: After eating, rinse the mouth several times. Otherwise, it causes one to suffer from dental caries.
The term "tooth worm" refers to the condition where worms eat into the teeth reaching the gums, causing pus formation, rotting, and foul-smelling discharge, resembling erosion; hence it is called tooth worm.
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. Wind-cold affecting the head and face transmits into this meridian, transforming fluids in the teeth and gums into pus. With blood and qi exhausted and unable to nourish the teeth, the tooth roots become exposed and protrude.
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth, and the Foot-Yangming Stomach Meridian covers the teeth. Teeth are the end of bones, nourished by marrow. If the meridians are deficient and wind pathogen takes advantage, blood and qi cannot moisten and nourish, causing the teeth to become loose.
Teeth are the end of bones, nourished by marrow. The meridians of the Hand-Yangming Large Intestine and Foot-Yangming Stomach both enter the teeth. If blood and qi are abundant, bone marrow is strong; even if teeth are damaged and fall out, they can regenerate. If blood and qi are depleted and wind-cold invades, leading to dental caries or gum recession, regeneration cannot occur.
The term "loose teeth sound" refers to wind-cold lodging between the teeth and gums, causing gum recession and pus discharge, making teeth sparse. When speaking, air passes through the gaps creating a sound; the world calls this "loose teeth sound."
Teeth are the end of bones, nourished by marrow. The meridians of the Hand-Yangming Large Intestine and Foot-Yangming Stomach both enter the teeth. Wind-cold invading the meridians damages bone marrow and blood, failing to nourish the teeth, causing them to turn dark black; this is called "li du" (generalized dental caries).
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. Wind pathogen lodges in the meridians, stagnating at the tooth roots, causing gingival swelling and pus discharge. It recurs after healing; this is called... [Text incomplete]
