I had my wisdom teeth extracted about 5 days ago, the stitches on one broke. do i need to get it restitched? there's no blood.

There is no need: If the area is clean and tissues are healing there is no need to have re sutured after the 5th day , there is no blood because the socket is healing..

You should be fine: Best to exercise caution and good oral hygiene. If you are concerned contact your dentist or oral surgeon for advise. Hope this helps.

Normally not a prob: The sutures (stitches) normally placed these day are dissoluble and end up coming out on their own. If there is pain, discomfort, or swelling, i would call the office asap.
