If it's a MOHS hardness of 5...that's a pretty damn abrasive toothpaste! Going on the teeth too...
I can't speak to the toothpaste method other than giving it a minty fresh aroma. I do have a friend who used a diamond paste to polish a TB crystal. Unfortunately he went too fast and it cracked from the heat. But others have have better success.
