Whiter Teeth

The container looked so small when I first received it. However, I can assure you that it will last just as long as a tube of toothpaste. I was scared that it would have a gritty taste and be repulsive due to the coloring. I was wrong! It does not have any terrible taste and the color didn't bother me except the first time. It safely removes any stains (coffee or smoking) and does so in a fast manner. I would say that I noticed significant results around 5 days after using (I used 2 times daily).
