Hi, I had all 4 wisdom teeth removed 3 weeks ago and I'm still not back to feeling normal! I got stitches in the bottom right extraction site, which still haven't dissolved, should I be going back to the dentist to get them removed or should I continue waiting for them to dissolve? The gum around the stitches appears to be redder than it was a week ago, is this a sign of infection? Also, my left ear feels blocked and I feel some pressure behind my left ear when I lay down. Are blocked ears a sign of infection?

I've been contemplating going back to the dentist to get it checked out, but I don't want to waste their time if I'm just being overly paranoid!

I appreciate any advice I can get! Thanks!
