Excellent toothpaste. Natural completely, so do not foam, just a little of lemon flavor (which of course is a plus - no acidity is not), but perfect teeth cleaned! I use together with the child, because "for kids of all ages" :) I decided to add a review because of the recurring comments with pressed-caps Locke about the lead. Inform - lead is in any clay (this naturally: lead is contained in the natural, minimal quantities in the soil, clay and the like), and California law requires that about any number of lead has been mentioned on the label, which makes manufacturer. Once again - for a minimum of lead as in any other clay.
