Chris,

I've had 4 surgeries on my tongue, plus a few biopsies that required stitches. I had stitches fall out a few times, but from what I recall it was perhaps 2 days post-surgery. I'm not sure why, but I'm sure it has something to do that the tongue is a muscle which is nearly impossible to keep immobile. From what I recall (my last surgery was in 2011), my doctor didn't seem overly concerned and I don't believe he even replaced them.

I'm glad you were able to see the doctor today. I hope the swelling goes down soon and no more stitches come out.
