Is toothache caused by “excessive internal heat”?
Tooth pain results from stimulation of the dental pulp. Among all conditions capable of stimulating the pulp, dental caries is the most common cause. Pain—arising from various etiologies—is one of the most frequent symptoms encountered in oral diseases. So, is tooth pain caused by “excess internal heat” (a traditional Chinese medicine concept)?
Is Tooth Pain Caused by “Excess Internal Heat”?
Tooth pain is not necessarily due to “excess internal heat.” If the pain originates from the gums—accompanied by purulent discharge, ulceration, or halitosis—and if the patient has recently consumed spicy or “heat-inducing” foods and experienced significant stress, sleep deprivation, or overwork, then such tooth pain may indeed be attributable to “excess internal heat.” However, if the pain stems from dental caries, it is not caused by “excess internal heat.” Similarly, pain resulting from pulpitis secondary to caries is also unrelated to “excess internal heat.” In cases truly attributable to “excess internal heat,” local dental treatment can be combined with traditional “heat-clearing” medications such as Niuhuang Jiedu Pian (Calculus Bovis Detoxifying Tablets). Conversely, for pain caused by caries or acute pulpitis, “heat-clearing” medications are ineffective; professional dental treatment at a hospital is essential.

Systemic complications of tooth pain: Bacteria residing in dental foci may trigger systemic diseases, including subacute bacterial endocarditis and rheumatoid arthritis. Periodontal disease and diabetes mellitus exhibit bidirectional interactions: diabetic patients typically suffer from more severe periodontitis than non-diabetic individuals, and uncontrolled periodontitis can adversely affect glycemic control and diabetes management.

Local complications: Chronic oral inflammation may develop into a persistent focus of infection, compromising the health of adjacent teeth, the jawbone, and the entire oral cavity. We hope this information proves helpful to you!
