Patients are nervous after undergoing an extraction of an ambulant tooth, fearing that the wound will grow poorly or that there are any special considerations that need to be made. First of all, patients are advised not to be too nervous, as ambulant tooth surgery is a minor outpatient procedure that involves incision opening as well as incision suturing. After the extraction of ambulant teeth, patients are generally advised to bite down on the cotton for half an hour until there is no excess exudate in the mouth, and then spit out the cotton. Secondly, patients are advised to pay attention to oral hygiene, especially the cleaning of the incision, in order to prevent the occurrence of secondary infection of the incision. At 7 days after surgery, patients are generally advised to visit the clinic in time to check the healing of the wounds.
