--------------------
The reason the whitening toothpaste is called "Whitening" is because the paste is more abrasive than the non-whitening toothpastes. The stain that the whitening toothpaste gets rid of is on the surface of the tooth usually caused by the food you eat. Where whitening strips are for the stain that they call Intrinsic stain (has been absorbed into the tooth) Because the whitening toothpaste is abrasive, it Can wear at your teeth and gums (depending how hard you brush, type of toothbrush, how often...) It's tough to say how it would affect your teeth since I don't know your history. But as long as you don't have an issue with weak enamel and don't ruin your toothbrush bristles within a month(meaning you brush too hard), you should be fine. You may want to ask you Dental Hygienist the next time you go in for a cleaning,(or your dentist if you see him/her first) You probably will not see a Huge difference in the whiteness of your teeth unless you have heavy deposits on your teeth. After you use the toothpaste it will stay white as long as the debre is gone. Things that cause stain on the outside of your teeth: coffee, coke, tang, tea, smoking. If used enough, some of these stains can be absorbed into your teeth as well. If you want to get your teeth whitened a couple of shades you may want to use a strip or whitening product which whitens the inside. I personally use Colgate total whitening. (I also switch off with different regular pastes as well) Be weary of online whitening products. I have not been impressed with a lot of them.
