I had my upper two wisdom teeth removed 5 days ago. Today I noticed that there is a round piece of skin hanging down from where my wisdom tooth used to be. This is strange, because the stitches from my incision are no where near where this loose skin is hanging from. It hurts, and is annoying because I keep accidentally bumping it with my tongue. I am worried it might come loose, not to mention I have no idea what it is and I'm freaking out.
