Wait a minute, you're missing the point. The dissolvable stitches need to stay in place until they dissolve, by which time the incision will have knit together enough to hold itself together without the stitches. You don't want the stitches to dissolve too soon. Follow the instructions given to you by the dentist or oral surgeon.
You really don't want to hurry the stitches so they will come out. They stay as long as needed to close whatever was owned in your mouth. If you try to quicken the process you can get food caught inside which will attract bacteria causing infection and more pain than you would want. Give them a little more time.
