In the case of gingival tumor removal for a single tumor, the general surgical time is between 0.5 and 1 hour. Because it is not all about the surgery time, the gum tumor oral cavity is a contaminated environment and bacteria can be present inside the oral cavity at normal times, and the surgery needs to be performed with relative sterility, so oral disinfection is required before the gum tumor can be removed. After the removal of gingival tumors, not only the process of removing the tumor, but also the surrounding gums and alveolar bone need to be trimmed, because to reduce the recurrence of gingival tumors, the gums need to be restored to a normal scallop shape during the trimming process in order to restore the role of aesthetics. In fact, the removal time is relatively quick, but the preoperative preparation for the removal and the postoperative revision of the gums, as well as the possible alteration of the alveolar bone or the need for adjustment, will take some time. If the tumor is large and affects 2-3 teeth, or even if the tumor is present on both the buccal and lingual sides, the surgery time will be extended, which may take 1-2 hours or longer.
