If he is grinding his teeth he is really in pain. I think you should either put him down or take him to the vet to have it done. If it were a dog or cat, isn't that what you would do?
It is not difficult to euthanize a rabbit. Get a piece of rebar or even a broomstick. Put the rabbit on the ground. Place the stick across the back of his neck and put a foot on each side of it. Take hold of the hind legs and pull firmly. The neck will break, killing the rabbit instantly. You can cry afterwards, it is allowed. (((Hugs)))
I'm not trying to be hard on you. Believe me, I know what you are going through. But sometimes it is the only thing we can do for our animal friends.
