Been using it about 3 weeks now and I must say my teeth look cleaner but not whiter. I use it morning and night and then use my normal toothpaste, but I'm not convinced it's whitening them any more than my toothpaste does." In contrast, another buyer was thrilled with the powder's impact on tea stains: "Got the powder to use with my regular toothpaste and it has made a huge difference with tea stains." This MySweetSmile sale will run between April 30th and May 5th.
