Whether and when the stitches need to be removed for wisdom tooth extraction should be determined by the material of the stitches and the doctor’s orders. There are several kinds of clinical sutures for the oral mucosa, including the conventional non-absorbable mousse sutures and many different kinds of absorbable sutures. If absorbable sutures are used, there are some cases that can be considered not to remove them, such as collagen-based sutures that are absorbed more quickly. Of course, there are also cases where non-absorbable mousse sutures or absorbable sutures with longer absorption time are applied. In these two cases, removal can be considered in order to keep the foreign body in the oral cavity for a longer period of time. However, in this case, it is best to consult with the doctor who extracted the patient’s teeth, because this is an individualized issue and the extraction doctor has the most say.
