I LOVE CREST WHITE STRIPS! I had always been self conscious of my teeth but now I love them. They're pretty expensive but so worth it. I did the 10 day pack. It made my teeth sensitive but once I finished the treatment it went away. My teeth were noticeably whiter and I got a lot of compliments. It's been 3 months since I finished and I still notice a difference.

It came in a plain brown box with no instructions. That's not what the item description and picture say or show. I've purchased Crest white strips before but it NEVER came like this. I read other reviews and others are saying the same thing. Very disappointed!

I've been using these since high school (10 years) and they are incredible. They make my teeth noticeably whiter after just one use. I typically only use one strip every couple of weeks now for maintenance. The only downside is the sensitivity it causes but only lasts a day or two.

I've only used this set once, mostly due to the high price. While it does whiten your teeth pretty well for being something you can get at the store, it did make my gums hurt/burn when the strips were on. This discomfort is not awful, but it seems like there are other ways to whiten teeth. For the price it does it's job, but be warned about the burning.

After using this product I can honestly say that it works. My teeth were noticeably whiter.The application is relatively easy.The cost is on the higher end,but cheaper and quicker than a professional clean at the dentist. I would not recommend prolong use because a lot whites can make enamel weaker,thus causing sensitivity;and that is a whole other problem. I would recommend this to a friend.

If you're looking for a cost effective way to whiten your teeth, this product may be for you. I've tried this product twice and each time my gums became more sensitive. Despite every effort to keep the gel from touching my gums, the product slides because it's not a true fit.

For the price these whitening strips are very good and after trying them for a few days the difference in the color of my teeth was definitely noticeable. I have worn the strips for an hour at a time and gone about my daily business. When it comes to taking the strips of its a bit difficult to do so and this part is where i got to taste the whitening ingredients which was not very pleasant. If you could make it easier to remove the strips after the treatment it would be brilliant.

These are amazing!! I've been using them for years and a box lasts me so long because you only need to use them a handful times a month. I don't recommend leaving them on for too long because they can cause sensitivity. Most of the time I leave them on for less than the recommended time and still get results!

This product was super easy to apply and keep on your teeth. When it's on right it definitely sticks on and is hard to move which is good because you can still feel comfortable to chat with people. You will definitely notice a whiter smile after a few days of using the product. In fact I totally got compliments on how white my teeth after :) The only thing is it does make your teeth/gum sensitive for awhile after so doing it at night might be best and of course it has a weird taste to it but what teeth whitening product doesn't have those issues?

For the price these do a pretty good job! I wouldn't say they are the best option for whitening your teeth ever but they're are nice for at home use when you don't have a ton to spend on your smile. Good for quick whitening pick me ups before important events.
