How to determine if a toothache is caused by excessive internal heat (fire) or dental nerve pain

To determine whether toothache is caused by excessive internal heat (so-called "fire") or dental nerve pain, the main criteria include the nature of the pain, associated symptoms, and possible causes. Toothache caused by excessive internal heat typically presents as a dull or aching pain, relatively mild in intensity. It may be accompanied by symptoms such as dry mouth, bad breath, and sore throat, and is often triggered by improper diet or high levels of psychological stress. In contrast, dental nerve pain usually manifests as intense, sharp, and persistent pain, which may be caused by dental conditions such as dental caries or pulpitis. The pain is difficult to localize and is often accompanied by localized swelling, fever, and other signs of inflammation. Additionally, dental nerve pain typically intensifies with exposure to hot or cold stimuli, whereas toothache caused by excessive internal heat may not be significantly affected by such stimuli. Therefore, by comprehensively evaluating the nature of the pain, associated symptoms, and possible causes, one can make a preliminary determination of whether the toothache is due to excessive internal heat or dental nerve pain. It is recommended to seek timely medical attention for accurate diagnosis and treatment.
