Remineralizing Tooth Powder – what in the world is tooth powder?? Garner's Garden has developed an all-natural teeth whitener that doubles as an effective oral deodorizer that focuses on not masking oral odor, but rather adsorbing (yes, aDsorbing) odor-causing bacteria that reside in your mouth. It will also assist in whitening your teeth over a period of time. Pair this oral care product with Garner's Garden Antibacterial Mouthwash and Oxy Pulling Pre-brush Oral Rinse for the most effective results.
