This topic has come up, before. The only thing that I can say about Bentonite is that I use it in ceramic glaze recipes. Personally, I would stick to the original protocol: OP; Seasalt water rinse; non-flouridated toothbrushing. Of course, anyone can add or delete anything that they wish with regard to anything, in life! I just know what's worked for me, so I'm not going to try to fix it if it isn't broken.
