If a patient has dental caries and is experiencing considerable pain, and there are no medications available nearby, they can temporarily use Sichuan peppercorns for pain relief. This is because certain components within Sichuan peppercorns can alleviate some of the pain, although they do not treat the dental caries directly. Thus, it is recommended that if a patient is suffering from toothache due to dental caries, they should seek timely treatment at a hospital. The specific treatment plan should be based on the extent of damage caused by the dental caries. If the damage is minor, the tooth generally does not require special treatment; however, if the dental caries are severe and have damaged the tooth structure, root, or even the dental nerves or gum tissue, it is advisable for the patient to consider tooth extraction followed by a dental restoration. The specific recommendations should still be based on a doctor’s diagnosis and a tailored treatment plan should be established.
