So, I ended up having 2rcs last Wednesday. 1 upper 1 lower. The lower one went on just fine no infection, no pain.
However, the uper one, which I might add I have neglected for 2+ years, seemed to have developed an infection.
After 2 days of brutal (severe would not describe it accurately) I went back to the doc yesterday and he said that we can still save the tooth by draining it. Had that done and I must admit for the rest of the day I did feel much better.
But as I'm writing this the pain did come back.
My few concerns are:

1. Is it possible that the prescribed antibiotic (cephalexin) is not working in fighting the infection? I had previosly had abscesses that I had great success at treating with amoxycillin...
2. The pain was so brutal that 2 vicodins would barely make it go away for about 1hr or so. After that I still had to endure it for the next 3hrs when I could take the vicodin again.
3. The doc did mention that if the infection persists, he could end up shooting iodine up the canal, to make sure that the infection is completely cleared. I have not heard of this procedure before and was wondering how viable it is???

Lastly, I'm not really hung up on saving this tooth as it is on the side and would not mind that much having it extracted if that would guarantee to take care of the infection/pain.

Any advice is greatly appreciated.

Sincerely,
Tony
