In the vast majority of cases, there is no significant pharyngeal pain after tooth extraction, and the pharynx is relatively distant from the location of the extraction wound, unless there is a local infection that spreads after the extraction and causes pain in the pharynx. If this is the cause, it is important to apply antibiotics for treatment as soon as possible after tooth extraction. Antibiotics can be chosen from cephalosporin and tinidazole class, and the combined application is very important for local infection after tooth extraction and is also very beneficial for the treatment of sore throat. The majority of patients can slowly recover after taking oral anti-inflammatory drugs for about 7 days. If the condition progresses more seriously, even with interstitial infection causing respiratory distress, intravenous drips are needed, which can be given intravenously with cephalosporin and ornidazole, and also with hormonal drugs, all of which will be of some benefit, and the majority of patients will slowly disappear in about 1 week.
