Tooth extraction is usually not recommended when you have a toothache. A toothache can be caused by inflammation, a combination of the extraction wound as well as the inflammatory stimulus, which causes the inflammation to spread and the pain to worsen. This encourages the inflammation to spread locally around the extraction socket, making the extraction socket wound less likely to heal. In severe cases, infection may also occur, and if the infection is secondary to osteomyelitis of the jawbone, it may cause infection of the teeth and the space around the jawbone, which may lead to facial swelling and pain, as well as craniocerebral infection. And when the toothache, the tooth may not be sensitive to anesthetic, difficult to achieve a better anesthetic effect, the patient is difficult to tolerate the pain, affecting the extraction of teeth. Patients with toothache should consult a doctor in time and follow the doctor’s instructions to avoid delaying the condition.
