Toothache after spraying Jin Hou Jian spray for oral ulcer

Oral ulcers are a common oral mucosal condition characterized by one or more painful, round or oval sores in the mouth, typically with a white center and red border. Jinhoujian spray is a commonly used medication for treating pharyngitis, containing anti-inflammatory and analgesic ingredients, and is sometimes used to relieve pain from oral ulcers. However, if toothache occurs after using Jinhoujian spray, it may be due to certain ingredients irritating sensitive oral mucosa or teeth, or because pain from the ulcer has radiated to the teeth. The toothache could also stem from other dental issues such as dental caries, pulpitis, or periodontal disease. In such cases, use of Jinhoujian spray should be discontinued, and medical attention should be sought promptly to determine the exact cause of the toothache and receive appropriate treatment.
