Toothache after tooth extraction may be caused by post-extraction inflammatory reaction or dry socket, which can be relieved by oral pain medication, local debridement, etc. Patients should follow the doctor’s instructions for treatment. 1. Post-extraction inflammatory reaction: If the toothache is caused by post-extraction inflammatory reaction, the patient’s pain symptoms are generally mild and normal. Patients can take oral pain medication as prescribed by the doctor, including acetaminophen, sodium rosoprofen, ibuprofen, etc., which can relieve the symptoms of pain. 2. Dry socket: Dry socket is a limited secondary infection of the bone trauma of the alveolar fossa after tooth extraction. If the toothache is caused by dry socket, the patient’s pain symptoms will usually be more intense, and the pain will radiate to the head. The doctor will provide local anesthesia to the patient, and then carry out local debridement to remove the decayed material thoroughly and rinse the extraction socket cleanly, and then put in the iodoform gauze, and the gauze can be added with anti-inflammatory and analgesic drugs, such as benzocaine powder and clove oil, to alleviate the patient’s symptoms of pain. Patients should follow the doctor’s instructions to actively cooperate with the doctor’s treatment, do not blindly treat yourself, so as not to delay the condition or cause adverse reactions.
