 My colleagues use it that understand health. We don't want tooth decay. We don't want gingivitis. Bad breath. And we don't want all the toxins that are in the prototypical toothpaste. I don't care which one you name, Crest, Colgate. Look at the ingredient list and so many of those four, five, six-syllable words you can't pronounce. Spry toothpaste and mouth rinse.
