Re: what kind of toothpaste do you buy?

Thanks. Clays are typically alumino-silicates and often don't contain strontium. I don't know whether it would be overkill to add these, but it is clear that in nature, one's teeth grinds on IP6 but that most diets of today are void of this activity, and restoring natural behaviour with regard to how minerals are encountered by the body in nature just seems like a good idea. Rubbing IP6 on the teeth is a natural thing to do. Consuming strontium in trace amounts appears to catalyze bone and tooth mineralization.
