Within days of using Natural White I was noticing a difference and w/in two weeks I was amazed at how many shades my teeth had lightened. Tried other products (way more expensive) and never came close to these results. Was using just the gel but plan to look for the toothpaste and other products they have to keep my teeth looking so nice.

I experienced no irritation leaving it in more than 5 minutes. My teeth yellows due to smoking and the whitening that I get are wonderful.

Great results for a great price!

It made my teeth whiter after the 1st use! I was amazed, honestly, considering I'm a 30 year old smoker of 15 years, and I drunk tea and coffee daily for as long as I can remember!
