Inflammation period is not recommended for tooth extraction for the following reasons: 1, inflammation period tissue is in a state of edema, blood vessels become brittle, especially in the early stage of inflammation. If the tooth extraction at this time will be particularly painful, and anesthetic can not effectively penetrate into the tissues to make the pain worse, the patient or the patient can not tolerate; 2, inflammatory substances are easy to spread to cause bacteremia, increased body temperature and a series of complications; 3, inflammation during the period of tissue vascularity becomes brittle, more bleeding during the extraction, extraction is not conducive to stop bleeding after the tooth. It is recommended that patients take anti-inflammatory drugs when there is inflammation, if penicillin is not allergic you can take amoxicillin and metronidazole, and then extract the tooth 4-5 days after taking the medicine. To summarize, extraction is not recommended in the early or middle stage of inflammation, but can be considered in the late stage of inflammation when necessary due to more limited inflammation.
