I'm 8 days post op of #19 extraction and grafting as it was absessed. On day 5 one of my dissolving stitches broke but I did not have any bleeding. At night I have what I will describe as numbness on my left cheek, the ares where stitch broke is tender and feels puffy, today the teeth on side of my extraction feel weird. I don't have a fever. I'm about to leave town for 4 days should I be concerned?
