When diagnosing toothache due to dental caries, press upon the pulsating points of the Yangming channels; if there is pathogenic influence, there will be localized heat. If the condition is on the left, the left side will be hot; if on the right, the right side will be hot; if superior, the superior part will be hot; if inferior, the inferior part will be hot.
The Hand-Yangming Large Intestine channel has a branch entering the nose and teeth, named Daying (Note: The text contains an error here; Daying belongs to Foot-Yangming Stomach, while the point entering teeth from Hand-Yangming should be Heliao). For lower dental caries, this point is selected. If accompanied by aversion to cold, tonification is applied (some versions say selection of the point); if not aversive to cold, sedation is applied. (*Lingshu* names this point Heliao, or alternatively Daying. Detailed examination shows that Daying is issued from the Foot-Yangming channel, so it should indeed be Heliao. However, for lower dental caries, one should also select Daying of the Foot-Yangming Stomach channel, which can be verified in practice). The Hand-Taiyang Small Intestine channel has a branch spreading through the teeth, named Jiaosun. For upper dental caries, select the point located anterior to the nose and nostril (one version says before Heliao). At the onset of the disease, the pulse is vigorous; if vigorous, apply sedation; if deficient, apply tonification. Another method states to select the point lateral to the eyebrow; at the onset, if the pulse is vigorous, sedate; if deficient, tonify. For loose and painful teeth without aversion to cold drinks, select Foot-Yangming Stomach channel points; with aversion to cold drinks, select Hand-Yangming Large Intestine channel points. For flaccid tongue drooping with vexation and oppression, select Foot-Shaoyin Kidney channel points. For polyglottis (swelling under the tongue resembling a second tongue), puncture the lingual frenulum with a needle.
For swelling and pain of upper dental caries, Mucuang (GB16) governs. For painful upper dental caries with aversion to wind-cold, Zhengying (GB17) governs. For dental caries pain, Fubai (GB12) and Wanggu (GB12) govern. For toothache, Quanliao (SI18) and Erjian (LI2) govern. For upper dental caries, Duanduan (CV15) and Ermen (TE21) govern. For bleeding between teeth, injury from sour/rotten substances, receding gums with pain, inability to open the mouth, and traction to the nasal cavity, Yinjiao (DU28) governs. For cheek swelling, tight lips, pain at Jiache (ST6), and inability to masticate, Jiache (ST6) governs. For painful upper dental caries with aversion to cold, Shangguan (ST7) governs. For facial paralysis (deviation of mouth and eye), yawning, lower toothache, cheek swelling, aversion to cold, inability to close the mouth, inability to speak, and inability to masticate, Daying (ST5) governs. For yawning, lower dental caries, lower toothache, and parotid swelling, Xiaguan (ST7) governs. For inability to masticate due to toothache and swollen gums, Jiaosun (TE14) governs. For facial paralysis with deviation, inability to open the mouth after yawning, Yifeng (TE17) governs. For swelling under the tongue, difficulty speaking, flaccid tongue, and deviation/malalignment, Tonggu (BL63 or BL89 depending on context, likely BL63 Taixi area or local point) governs. For swelling under the tongue, difficulty speaking, flaccid tongue with salivation, Lianquan (CV23) governs. For facial paralysis, puncture Taiyuan (LU9) to guide the qi downward. For swelling and foul odor in the mouth, Laogong (PC8) governs. For lower toothache in the mouth with aversion to cold and swelling, Shangyang (LI1) governs. For dental caries pain with aversion to coolness, Sanjian (LI3) governs. For facial paralysis, Pianli (TE6) governs. For mouth and tooth pain, Wenliu (LI7) governs. For lower dental caries causing upper toothache, Yimen (EX-HN?) governs. For toothache, Sidu (TE10) governs. For upper toothache, Yanggu (SI4) (one version says Yangxi LI5) governs. For dental caries pain, Hegu (LI4) governs; it is also said that Shaohai (HT3) governs. For flaccid tongue drooping with vexation and oppression, Yinjiao (CV13) governs.
