I had #15 extracted 8 days ago because of abscess. About 3 days after extraction, the gum around the site became swollen and distracting to my tongue and cheek. It seems to be the gum area next to adjacent tooth. Day 8 and swelling has not gone down. It seems less distracting at times and more so at other times. Is this normal or could infection be involved? I have been on Amoxicillin since extraction.
