I drink coffee so often that I was getting a bit stressed about my teeth turning slightly yellow. I spotted this teeth whitening product at a pharmacy or supermarket and was tempted to buy it, haha. I looked it up and found that it's fairly easy to use, affordable, and great that I can try it at home. Since it's summer, I tend to drink even more coffee and other beverages... While it won't make my teeth as white as if I'd had a procedure, I think I can expect at least some whitening, so I recommend it, haha.
