I have tried everything, but it has been awhile since I have gotten my teeth cleaned, due to health reasons and "time just flies by" at this stage of the game. I am on my 4th strip, and with each time, I kept on seeing more and more whitening. Very pleased at this point. Hoping to get to where I want them to be...fingers crossed

I was very disappointed with this product. I religiously did it for the allotted amount of time and read the directions thoroughly, however, saw no results. I was about to go on vacation and wanted a nice white smile. Please don't waste your money. There are much better products out there and those will show results and won't cause teeth sensitivity.

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!

I swear I get compliments on my teeth all the time because of this stuff. I used a professional writing paste when I was younger and now all I use are these crest strips to maintain the pearly whites. These are amazing and I don’t have to use them daily just whenever I want a touch up!

I have experimented with many different "whitening" products, including the professional trays and product you get at the dentist. The professional stuff definetly worked but is much more $ in the end (trays and gel). I liked how this product stayed put, and I didn't leave a nasty taste in my mouth. The best part is it's 30 minutes, and not an hour! Crest has definetly improved their product with the "stay put' strips, and the effects that it has after just 1 use! I did my first application this evening, removed the strips and my teeth just look brighter!!!! An A+++++++ product!

I know some people think that it’s from a box how could it work?! But it truly works! It’s so easy and so fast and hello you can do it at home, in the car , literally everywhere! And i totally recommend this to anyone who doesn’t want to spend a ton of money on teeth whitening!

The Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit gave me my confidence back to smile. Prior to using these white strips, my teeth looked yellow and I was insecure about smiling or wearing certain lipstick colors. However, after using this whitening kit, I had a noticeably brighter, whiter smile. However, the kit irritated my gums and left my teeth much more sensitive.

These work well for white strips you can buy at a local store. I like that you can stretch the strip to avoid gym irritation and to cover more space in our mouth. I notice a little soreness if I’m using these day after day after day so I normally spread them out and do two days in a row and then take a day or two off due to my teeth sensitivity. But they do whiten my teeth well!

I had a chance to try Crest 3D Whitestripsin the weeks approaching my step daughter's wedding. I absolutely loved the results! Not only were they easy to use, but the wedding photos turned out great with my gleaming white teeth! I had several people say how much younger I looked!

I used the Crest Classic Whitening Strips previously and had great results (didn't even need to use the entire box at one time to get the results I wanted). I was quite disappointed that the Professional Effects did absolutely nothing to whiten my teeth. They did stay put much better, however. I do not have subborn stains or overly yellowed teeth; I'm not a smoker but I do drink coffee. I just wanted to give my smile a brightening boost. Unfortunately, I will be looking for other whitening products unless the Crest Classic Whitening Strips return to the market. Luckily I was able to get a refund.
