I have used these for years and always get compliments on my smile. I was worried about damaging my teeth with these, but my dentist and oral surgeon friends assured me these were enamel safe. To avoid him sensitivity with these, be sure to swish with lukewarm water really well after removing the strips, so you don't leave the irritating gel on your gums. I used these several times in high school first, and now (in my 20s) I buy a box once a year and I use them year-round to touch-up before interviews, dates, holidays, weddings, etc.

These are definitely my favorite whitening strips. I only use them before special occasions and events but they do make a difference. I use them every other a day the week before I have some sort of event and they work. They can make your teeth sensitive so I don't recommend using them regularly, but it's a good product.

Crest white strips do a great job at teen whitening. Although pricey, I think it's worth the money if you're looking for effective at-home whitening treatments. I would recommend following the directions as is. Don't leave them on over a long period of time because too much exposure to these chemicals are bad for your teeth!

These things are amazing! Really noticeably whiter after using one box. Also great that they're the only FDA approved teeth whitening product. 30 minutes a day is very easy and you can go around without worrying about them slipping off your teeth. Would recommend to anyone

I have only used one strip so far and I can already tell a difference. We all know someone who doesn't have the whitest teeth(that's me) this product is perfect for someone who is looking to whiten their smile(also me). Just a warning they taste disgusting, but pain is your gain right?

I have been using this product for 10 years. I always get compliments on how white my teeth are. I wear any shade of lipstick with confidence. I have recommended them to all my friends and family, they all thank me after they see their results. If you have tried but they make your teeth too sensitive try two tips. 1) When starting the treatment start slow. Recommend time of wear is 30 mins, the 1st strip you use wear for half the time and build your tolerance. 2) Two weeks before you start treatment use a sensitive toothpaste and continue using while you finish your treatment.

I have been whitening my teeth for years, I go thru spurts where I will whiten for 3 months at a time. Usually I find that my teeth get a little sensitive... I've been using these crest white strips for the last month, daily use leaving them on for 30 mins and I have NO sensitivity. my teeth are dramatically whiter, and they are easy. Would highly recommend!

This is a great at- home teeth whitening kit. The strips stay on easily. I could see a difference after using one time. After using daily for a week my teeth were visibly whiter. I have sensitive teeth so using too much can leave them a little sensitive. But overall I would recommend this kind of teeth whitening.

The Crest 3D whitening kit is a must have for anyone who is dedicated to their teeth and oral care and wants their smile to look absolutely stunning. If you are looking to enhance your beautiful smile, look no further than this incredible product that will do just that and more

I love these whitening strips. They work really well. The only downside is that they do make my teeth a little sensitive, but I just make sure to brush my teeth with sensitive toothpaste a day before, day of, and day after and usually I'm good. I only use them about once a week.
