It will take some time for it to heal. Remember it takes longer to heal than it did to damage it. Also it's quite common to have a white tongue after surgery. I've had it after other surgeries and believe it has something to do with the breathing tube. Some people have a reaction to it.
I would expect it to take a few weeks for it to go away.
