I just came across another promising toothpaste brand: Urtekram. The products appear to be detergent-free, sorbitol-free, and organic. They make a children’s toothpaste! Tragically, I can’t seem to find a source in the US for less than $10 a tube, so I guess I won’t be rating it myself anytime soon. However, it appears to be more reasonably priced in Europe.
