Whether or not stitches are needed after the extraction of erupted wisdom teeth should be viewed to see the specific size of the eruption, if the crown of the erupted wisdom teeth is fully erupted, the maximum circumference of the crown has been exposed in the oral cavity, at this time, the removal of wisdom teeth only need to be applied to the tooth tappet, and then applied to the tooth forceps extraction can be done, this type of wisdom teeth can be considered without stitches after extraction. Because of the relatively small trauma itself, even without suturing the extraction wound will grow naturally. However, if the clinical eruption of the wisdom tooth is not fully erupted, there is still soft tissue covering the distal middle, then to remove this wisdom tooth will need to cut the distal middle gingiva. Sutures are recommended for this type of wisdom tooth extraction, as failure to do so is more traumatic and may result in postoperative wound exposure and infection.
