I just came across an interesting claim that monosodium phosphate will actually thicken the enamel on your teeth and prevent cavities. If it's true, I want to know! Quickly! I have a dentist appointmet next week that could perhaps have been avoided. In the course of my investigation, I found www.toothsoap.com. It's hard to tell whether the referred to book is necessary or just a good marketing device. Actually, there's a reference to toothsoap.com and the book on wiki.answers.com. Call me jaded, but I had to wonder if the owners of Toothsoap posted the wiki answer.
I'm going to spring for some monosodium phosphate and some toothsoap and report back in a month or two. Wouldn't it be wonderful if this were a journey to a new land where tooth decay is unknown, rather than a short walk down the primrose path?
