Its sunday night, my wife has her wisdom teeth pulled on friday morning, the teeth are not even bothering her anymore, but she has a few ulcers and one really bad that looks deep. Its fairly close to the area they operated on a few questions for anyone that can help .....

1. Is this normal?

2. What can u use to ease the pain? I used a little peroxide, but I know that cannot get near the surgery site so I was very carefull and dont think it helped too much

thanks
