There are conflicting stories on the effectiveness of turmeric whitening your teeth. We can only speak from what we have personally experienced and what customers have shared with us other the years.  Yes, using our toothpowder has increased oral health, including teeth whitening for some. Please keep in mind turmeric is a natural herb that has been used worldwide as a skin lightener and teeth whitener, but it will never work like a laser or chemical whitening treatment.  We have also had numerous customers share that our products have improved gum health. While this reaction is probably due to the combination of ingredients we use, we believe that the anti-inflammatory properties of turmeric do have a positive effect.*There are reports of turmeric staining teeth. We have been creating and selling toothpaste and powders with turmeric for over six years and have never had anyone share this with us. However, as responsible formulators, we take precautions, including limiting the amount of turmeric in our products.*We are not medical professionals.
