@Pippinwhite -- I think you'll be pleased with the change. I had to do that because I was getting some kind of fungal infection. I don't know that sodium lauryl sulfate was a factor, but when I switched to tooth powder, the fungus went away permanently.
Normally, I'm not one of these people who sees conspiracies and evil under every rock, but I do think more research needs to be done on some substances and the effects of their long term use.
At any rate, I know using tooth powder helped me. It certainly can't hurt to try it.
