Should you have a hole where your wisdom teeth were three days after the surgery or did your stiches fall out?

Yes, three days after surgery you will definitely still have a hole. It will probably take a few weeks to a month (on average) for the hole to close completely. As for stitches if you don't have dissoluble stitches you should go back to your dentist in about a week to have them removed, however I would recommend you ask your dentist for dissoluble stitches so you don't have to worry about any discomfort that may come with their removal.
