One of my wisdom teeth removal was stitched afterwards - it healed quickly. The other one came out far more easily - this wasn't stitched - and this was the one to take many months to heal. All is ok now tho fortunately
I was told it was just chance/one of those things
- I'd try to get some stitches in if I was you (inmho).
You will also be told to have plenty of salt water mouthwashes.
goood luck - let us know how it goes
