This is AMAZING. After one use my teeth are already looking brighter. I can't imagine consistently using it! It's so worth it! My teeth do get sensitive but beauty hurts.

I use these products every couple of years to make sure my teeth are looking good. I'm in avid coffee drinker so I feel like my teeth tend to be on the more yellow side. Using this product helps me keep a white smile. Will repurchase again.

I drink tea and coffee and my teeth where getting a little brown from it. I used the dress white strips kit and it help the appearance of my teeth to lighten them up. I need to get more my teeth appearance is not yet how I would love them to look.

I have been using these for a few months now and I see a huge difference after one use. I have been drinking coffee everyday for the past 5 years and this has helped with the slight stains that have shown up every now and again.

I like these Whitestrips from Crest! It does what it promises and I don't think my teeth get overly sensitive afterwards. I wouldn't use it for consecutive days though. I would definitely buy it again.

I have used these since high school and I am so impressed by how they work. I had yellow teeth so I used these daily as recommended and now as long as i use the strips once every week or two my teeth stay pearly white!

this helps whiten your teeth and it works but not as much as everyone would assume. you could use the whitening toothpaste as well for a better outcome

I'm a big fan of crest anyway but this is my favorite. Your teeth are super white and breath fresh. I use the whitening strips regularly and brushing with crest keeps them white.

This stuff is obviously a little expensive but it is sooo worth it! Brightened my teeth just after the first four days of using it! I've always struggled with keeping mine white no matter how much I brush. This stuff really helps!

This product is good. It's real and noticeable. Not magical. I recommend brushing your teeth extremely well and “drying them” prior to application. Don't overdo the time and don't use them all the time. But yes good investment for sure.
