question: I got my wisdom teeth removed 10 days ago. One of the stitches in my gum came out today, the spot where the stitch was has had a lump all along. The stitch is gone but the lump is still there. It doesn t hurt at all and it s not discolored. Is it normal for there to be some swelling just from the stitch being there or do I need to have the lump looked at?
