How many teeth can be extracted at one time is usually not clearly defined, it depends on the patient’s tooth position, dental lesions, physical condition, etc. For poor physical condition, 1 tooth can be extracted at one time, and for good physical condition, 2~3 teeth can be extracted. Generally speaking, it is safe to control the number of extractions within 2~3 teeth at a time. The number of particularly loose teeth can be increased appropriately, and comprehensive consideration should be given to whether the patient can tolerate it. If the patient has a history of hypertension in the past, a single tooth can be extracted after controlling blood pressure, which can be done in several sessions. For some teeth and patients with severe bleeding gums, usually only one tooth can be extracted at a time. Usually the number of teeth extracted at one time should also not be too many for patients with high blood sugar, and should be controlled within one tooth to avoid causing local soft tissue infection. If a patient needs to extract multiple loose teeth on the same side in a row, it is safer to control it to less than 4 teeth if physically possible. Patients are advised to have their teeth extracted under the guidance of a professional doctor according to their own situation.
