Hello. I had 4 molars extracted 7 days ago. All seem to be doing fine except one on the top right, second from back. I previously had a root canal in this tooth, and upon extraction there was some difficultly getting it out. The tooth ended up cracking and the surgeon informed me a piece of root tip was left behind, but should cause no problems.

The last several days there has been a foul smell coming from that tooth, and if I put a piece of gauze there, there's this yellowish/brownish discharge that smells very bad.

I'm not experiencing any intense pain, a bit of discomfort but ibuprofen takes it away. When I wake up I have a horrible taste in my mouth from it.

I've been swishing with salt water religiously in case of any food particles. I can see the clot still there, so it's not a dry socket. I also don't have any intense pain or swelling or fever, so I didn't initially suspect infection. I go Saturday to get my stitches out but I can't help but be worried.
