That's funny how some of the old brands just arent around anymore. The stuff i use is just a combination of recipes I found online, for natural toothpaste. I just tweaked it to my liking.
This brings back memories. My Dad used to use an old brand Py-co-pay that was actually a powder. It smelled like baking soda.

Yeah. Sometimes they were good products that just faded away because they weren't popular anymore.
