Back in the day, many, many moons ago, when we were discussing toothsoap on another forum, many soapers with gingivitus reported that their dentists were all amazed at the improvement to their gums and they needed to come less often. It's a good thing.
BTW: I brush my teeth with liquid soap in a foamer... easy to use, flavor, and tastes a bit better than the hard toothsoap.
Great idea, Zany!
