I had a root canal done on the tooth next to my front tooth in May, the tooth was a little sensitive and I had a little swelling on roof of mouth, she did root canal and stared the crown that day. Was put on antibiotics but had some issues with them, so she switched me to a zpak. Went back and told her tooth was tender and she said it could be tender for a while.

I do wear a partial for some missing back teeth, so I went to the dentist on Monday as I still have some swelling on the roof of mouth by this tooth and a little discomfort, not severe pain. The dentist that did the work was no longer there so I saw another, he did X-ray and said there is no infection, but if I wanted he would prescribe me some antibiotics cuz it couldn't hurt.

My question is why would I still have some swelling if there is no infection? All the other teeth are good, had a filling in the one beside this one done last fall, and he said they all look good. I am wondering if I should pull this tooth and get a permanent bridge, but then how long will I be without this front tooth, I work and don't want anyone to see me without a front tooth.
I haven't started the antibiotic, not sure if I should or not. Should I see another dentist? Since I already have a partial for missing back teeth, my friend says I should just get dentures and have all of the teeth pulled, but I don't think I want to do that. Any advice would help, thanks
