Four wisdom teeth can be extracted together, and hospitalization is usually recommended for removal; for outpatients, it is usually recommended to remove 1 to 2 wisdom teeth on the same side at a time. In modern human beings, the jawbone and teeth do not deteriorate at the same rate, resulting in most wisdom teeth being blocked and needing to be removed. The difficulty of wisdom tooth removal is determined by the degree of obstruction and root morphology. In the daily clinic, for some difficult wisdom teeth, usually only one wisdom tooth is removed at a time, and for those that are not too difficult, both the upper and lower ones on one side can be removed at the same time. The other side can be used for eating and to minimize the inflammatory response. Usually only hospitalization is used to remove all wisdom teeth at once. Whether or not to remove wisdom teeth and how many at a time, it is recommended to go to the dentistry department of a regular hospital and follow the doctor’s advice to take a step-by-step approach.
