You know how to tell if it's tongue bite? Nothing tastes right for a little bit. If that's happening why would you even want to waste the tobacco. It's been a long time since I've had tongue bite but when I did one thing that was very noticeable was that smoking made it worse. I'd let it rest. The idea of smoking through it really is as silly as asking if you should keep picking your scabs off. It's really about the same idea. If you've ever cut your mouth or tongue one thing you'll notice is how quickly it heals, which should give you an idea that it's a semi serious injury if it takes a few days to heal.
