Only used it one time. Not able to evaluate
Instruction are in very fine print. Am just going to rub  on gums. Cinnamon mint flavor. My guess is just be rubbing gums daily with improve their health. Can teeth regrow? Nope! Not sure how they make the claim, but they do back pedal a bit by stating healthy gums will result in healthy teeth…ok that makes sense. Was surprised that the return address on the package was right down the street from me….but maybe that’s just an easy distribution point. Will try for a month and evaluate then.
