I am a very active smoker God forbid because it’s so wrong but so difficult to kick the habit, so i have tried many whitening toothpastes, and none of them gave me any results, i think it’s the fact that you get a toothbrush and dental floss with the purchase that makes it attractive to buy but that’s all the toothpaste itself is a let down and oooops again money down the drain, rather visit your dentist there you will at least get value for your money.
