Would you pay $100 for toothpaste? Theodent 300 is a new dentifrice
that, instead of fluoride, uses a cocoa-
bean-derived active ingredient
called Rennou to stimulate the growth of tooth enamel. I’ve been using
the stuff for only two weeks, but I’m already more confident biting into
a piece of hard candy ($100,
theodent.com). (There’s
also “classic”
Theodent, with a lower-strength dose of
Rennou, which costs a much more
reasonable $10.)
