Depurdent Toothpaste
EPURDENT paste contains pumice as a method for cleaning and polishing, and thereby whitening teeth free of chemical bleaching agents. So you can get the smile you want, naturally.
Pumice is created when lava and water mix together. The result is an unusual foamy configuration.
Commonly it is used to remove dead skin from the body.
Pumice has been used for over 2000 years in ancient Chinese medicine to treat various illnesses.
More modern uses usually include cleaning and polishing.
