The length varies for how long dissolvable sutures will disappear. Most types of sutures will begin to be absorbed into the body or fall out within a week or two after they’ve been applied. However, there are others that can last up to several months. Your doctor should let you know how long dissolvable sutures will take to dissolve, or when to come back to have non-dissolvable sutures removed. If not, you can ask your doctor for a more specific timeframe. If your wound has fully healed, and the stitches are still bothering you, you can contact an urgent care clinic or your general physician to help remove them, rather than waiting for the dissolvable sutures to dissolve completely.
