【外感齿痛之因】齿痛属阳明少阳二经者多。胃家有热，胆经有火，外被风寒所束，
二经之热，不能发越，则郁而攻注作痛矣。

【外感齿痛之治】阳明风热者，葛根防风汤。阳明积热者，外刺合谷穴，内服葛根清
。少阳风寒者，柴胡防风汤。少阳风热者，柴胡清肝饮。肝胆积热者，龙胆泻肝汤。头痛恶
寒，太阳风寒外束，羌活汤。齿痛属阳明少阳者多，或有太阳症，故立后条。

[Exogenous and Endogenous Etiologies]
[Symptoms of Exogenous Toothache] The body presents with aversion to cold and fever, pain radiating to the head and eyes. In severe cases, it attacks and infiltrates the gums, causing swelling, pain, and suppuration. These are the symptoms of exogenous toothache.
[Etiology of Exogenous Toothache] Toothache mostly belongs to the Yangming (Foot-Yangming Stomach Meridian) and Shaoyang (Foot-Shaoyang Gallbladder Meridian) meridians. There is heat in the stomach and fire in the gallbladder meridian. Externally bound by wind-cold pathogens, the heat of these two meridians cannot be dispersed and vented, leading to stagnation and attacking pain.
[Pulse Signs of Exogenous Toothache] Floating and rapid pulse at the right Guan position indicates Wind-Heat in Yangming; Deep and rapid pulse at the right Guan position indicates Accumulated Heat in the intestines and stomach; Floating and tight pulse at the left Guan position indicates Wind-Cold in Shaoyang.
[Treatment of Exogenous Toothache] For Yangming Wind-Heat, use Gegen Fangfeng Tang (Kudzu and Saposhnikovia Decoction). For Yangming Accumulated Heat, externally needle Hegu (LI4), and internally take Gegen Qingwei Tang (Kudzu and Stomach-Clearing Decoction). For Shaoyang Wind-Cold, use Chaihu Fangfeng Tang (Bupleurum and Saposhnikovia Decoction). For Shaoyang Wind-Heat, use Chaihu Qinggan Yin (Bupleurum and Liver-Clearing Infusion). For Liver-Gallbladder Accumulated Heat, use Longdan Xiegan Tang (Gentian and Liver-Draining Decoction). If accompanied by headache and aversion to cold, indicating external binding of Taiyang Wind-Cold, use Qianghuo Tang (Notopterygium Decoction). Since toothache mostly belongs to Yangming and Shaoyang, but may occasionally present with Taiyang symptoms, this subsequent clause is established for supplementation.
