Noticeable change after first use but hard to position on teeth. They say not to use immediately after brushing but I think that's when they work best

I don't have any staining and my teeth aren't yellowed, but I was able to use these to amp up the whiteness of my teeth before my wedding and was very happy with the results!

I have a couple of teeth that seem to stain a lot, with the help of the whitening strips these stains just disappear. If you have tough stains that you don't want then I suggest the 3 D whitening strips.

I've used these and also recommended them to my patients. You will see significant results within 1-3 times of using them. I now only have to use them every once in a while, usually for special occasions. =)

it makes ur teeth really white but it also makes them very sensitive so it hurts when i drink cold water and stuff, don't know if i would buy again for that reason but it does the job

The best teeth whitening strips I have ever used. After just one use I could see a visible difference, and after a couple of uses others could see a difference as well. I wouldn't use any other strips after using these!

I love the before and after. This brand makes me feel super clean and fresh after I use it! I love how white my teeth look after using this toothpaste. I've used this for years it's way better than any other toothpaste I've tried.

These are the only white strips I use as of right now! I really Like them and they do show a difference after using them! It did meet all my expectations of the product. I would recommend to others

These strips are absolutely amazing. I know a lot of people have sensitive teeth when it comes to whitening strips but these really do the trick. They work the best compared to anything else I have tried.

Amazing. It takes a while for it to work, I would hope this worked a little faster, but over all, this product is great. If you are sensitive to taste I would most likely avoid. It does the job, but with time.
