I use these quite often and they always leave my teeth with a shade or two better than the previous times would highly recommend. I can be expensive but highly worth it.

This product does whiten teeth, but at the cost of comfort. Leaves teeth feeling sensitive and susceptible to new stains very quickly. I've only used the treatment one full time through, but the results were not worth the tooth sensitivity.

I have been using these for years now and always come back for more. These stay I'm place and are easy to use. I use it along side the crest whitening toothpaste and always get good results. It's worth the price.

Waynes teeth after a few uses. It can cause sensitivity to teeth. My teeth are naturally yellow and it helps a lot with the color. I like to partner this with Colgate whitening toothpaste and it works very well

These are the best at home whitening strips kits. I repurchase often and they always deliver wonderful results. The price is also great and inexpensive. Give these a try!!

I've gone through the uncomfortable professional whitening process, but the Crest 3D whitestrips do just as good a job without the high cost and discomfort!

Works great but takes a while to begin working. You have to continue using this for a while before noticing a change, but your teeth do become very white when continuing. Great for sensitive teeth and do not hurt the gums

Do not use on sensitive teeth until you strengthen them! This works very well after 30 mins I noticed my teeth were 2-3 shades whiter and the more I use it the whiter they get! I would recommend not using it too often as it breaks down enamel

These are great. But a little pricey. They really make your teeth white. I use them whenever I think about it and leave them in for about 30 minutes. Great results.

These crest white strips work wonders! They are very effective, and they are easy to use. The taste is pretty terrible, but it's worth it. I do usually have sensitive teeth for a few days after, but again it's worth it.
