Bought the Healthy Mouth Blend and Shine toothpowder whitener and I have seen whitening results in a month.
Neither have yet done anything for receding gums Ive had, although i don’t know if it’s designed to improve that specific aspect.
I have a small cavity and I will say it has helped slightly as far as it being as noticeable comfort wise. One month in, I would say positive results so far.
