Is It Normal to See the Knot From My Dissolvable Stitch After Having My Wisdom Tooth Extracted?

It can take longer than 1 week for the stitches to dissolve.  Don't worry about that.  If you find it uncomfortable, then I would recommend that you call the surgeon that removed your teeth and have him look at the area and remove the suture if necessary. 

Sometimes the suture takes more than a week to dissolve. Often times, the part of the suture that is inside your tissue dissolves and then the rest that is on the outside including the knot just falls off.  If you can give it a gentle tug and the knot comes right out without any discomfort, it is probably okay.  If not, then I would wait a little longer.
