Although the description on the tube says "gentle whitening" it burns my mouth to the extent that the tissue sloughs off. I'm hoping that it isn't my gums that are sloughing off when I brush with this toothpaste. I can say that my teeth appear to be slightly whiter, only a touch, and they do appear polished, using twice daily for about 3 weeks now. Because it burns the inside of my mouth and lips, I can only use a pea sized amount when I brush, and only after I brush first with Sensodyne. I am sure that if I could use the full amount each time I brushed, my teeth would be much whiter by now. I wish that the description included "tartar" control because it seems that all toothpastes that do this function burn my mouth. If you do not have this sensitivity, I would say buy it use it regularly as it would work to remove stains from your teeth.
