My favorite product to use for the brightening teeth is the DuraGrip!
I'm sure you've heard of this product before. I have been using it since 2003, and it works very well for me. DuraGrip is a tooth whitener and it is also a very simple, inexpensive and natural product. The DuraGrip is an inexpensive, easy-to-use whitening product that comes with its own instruction book.
DuraGrip Whitening Tooth Whitener This is a pretty simple and inexpensive tooth whitener. It is also very safe and natural. If you have dark brown to white teeth, you will love the DuraGrip!
DuraGrip is great! The only reason I don't rate it more highly is because it comes with a little bit of a warning. It does recommend using a toothbrush with it, however.
I have really light teeth. So I have to be careful about whitening my teeth. I really like the DuraGrip. My only complaint is that the instructions are really vague. But I found out that I need to put a little bit of toothpaste on my teeth first. I've tried it and I'm happy. It does whiten my teeth and it is easy. My only problem is that I don't like it because it is too strong and too aggressive.
