Review (4/5): Great for sensitive teeth
I like the fact that it doesn’t taste bad or leave a bad after taste. I have used it for over a week and only notice a slight difference in whiteness and it did not make my teeth sensitive. I’ve used charcoal paste but prefer the powder. Container appears to be bigger in picture so I was surprised at the small size when I received it. It did have a “best by” date of 11/2019 (ordered in February 2020) so ima not sure if that affects the quality of the product.
