they are the best in their category! 1 - easy and gentle whitening, especially for someone who has sensitive teeth 2 - 3 day only and you see amazing results 3 - if you think it can damage your teeth or enamel try use it each 2 day instead of each day 4 - price according to a dentist session super nice just one minus it doesn't make all your teeth white (only visible smile as a stripes short enough)

The product does exactly what it's supposed to do. My teeth were getting to a point where it was embarrassing, but I didn't have the money to pay for professional whitening. It's a great middle, as it whitens more than just whitening toothpaste but it isn't as expensive as a professional whitening treatment. I've been using this product for a while, and I have never had a bad experience with it, I would definitely say this is a must try. Effectiveness It did drastically whiten my teeth. Convenience Using whitening strips is never the most enjoyable thing, but these were the most convenient ones I've used. It had a minimal amount of wait time. Minimal Side Effects I had no side effects; however, it might not be the best for someone with sensitive teeth.

I love these Crest White strips products! They always work well on my teeth. I have tried the other kind of white strips and the other brands does not work as well as the Crest brand. These white strips have given my smile life and I am so happy and proud to have my smile now. Usually white strips take a few days to see visible results but with this amazing product you will see results within a few hours. I truly believe Crest lives up to its brand name! I am so glad to come across this product because it has made my smile come alive! I feel more confident with a white bright smile all thanks to Crest. But lets not forget the fact that it's easy to use. Every one should buy Crest White strips, you will have the best smile you ever had in your life. It is a necessity for me to use these white strips for my whole entire life. Effectiveness It really brightens within two hours! Convenience This product is easy to use and does not slip off your teeth.

This is definitely the fastest teeth whitening system I have ever purchased and used. I love the idea that you can have a brighter and whiter smile in just under two hours. The great thing about this product is it actually works. I noticed that my teeth were at least three shades lighter than they were two hours before I use the product. When I took the before-and-after photo I couldn't believe the difference that two hours would make. The only thing I didn't like about this product was the fact that you have to put it on for an extended amount of time and they are slightly uncomfortable to wear. Also it is extremely difficult to talk while wearing this product so I could not answer my phone or talk to anyone while I was wearing the white strips. however it's definitely worth the trouble if you wanted to whiten your teeth in a short amount of time. I also like that this product is extremely convenient you can buy it from any local grocery or pharmacy for an affordable price. If you would go to get your teeth professionally whitened it would be more than triple the amount that you pay for one box of crest white strips.

I followed the directions on the package and applied the strips, one for my top teeth, one for my bottom teeth, in the front only. These strips are not to be used for back teeth. I had a little bit of trouble at the beginning to remove the strip from the plastic it was on, but once I got a corner loose, the rest of the strip peeled off easily. The strip laid easily over my front teeth. I had a little trouble forming the edge of the strip over the bottom edge of my teeth though. There were small spots on the strip that would curl up and poke the inner skin of my mouth. I waited the two hours stated on the package. One has to be very conscious of the time when they apply the strips and what might be happening the next two hours of their life. I found the most convenient time for me was a couple of hours before going to bed. I also noticed that during the time the strips were on my teeth, they would slip and I would have to slide them back into position. They were awkward to use in that aspect. At the end of the two hours, I removed the strips and didn't really see much of a change in the whitening of my teeth.

When I first read about these I didn't believe the claim.I thought it was a waste of money and wouldn't work.Either that or it had really harsh ingredients that allowed it to achieve the results.Boy was I wrong.The strips were really hassle free to apply and keep on.They were not uncomfortable and they didn't scratch my gums like I thought they would.An hour is quite a long time to have something stuck to your teeth.I thought it was going to be a bother.I actually stopped noticing they were even on after a couple of minutes.The process is really simple and there was a picture illustration to help although it was self explanatory.I was also afraid it might wear away at the enamel since it whitens them so fast.The details on the package were reassuring.It said it was enamel safe.It lightened them a few shades so the results were really noticeable.My friends certainly noticed and complimented me on them.I am in love with these.

I find it quite difficult to give this Crest 3D White 2-hour express teeth whitening system a grade, because while it does a fantastic job of whitening your teeth in two hours, as promised, it absolutely killed some of my teeth while doing it and caused me some of the worst tooth pain I have ever felt. This works BUT is definitely not for sensitive teeth, Effectiveness I have to admit that the tooth whitening power of this product is quite impressive, and my teeth looked at least 2 shades whiter after one use. Convenience If you have two hours to kill, this product is very convenient, You can of course multi-task while whitening your teeth (at home, preferably), which is pretty nice if you don't want to go the traditional route where it usually two weeks of whitening strips use to get results. Minimal Side Effects As effective as this whitening product is, it is also equally as painful on your teeth. Some of my teeth became very sensitive after having the product on my teeth for about 15 minutes, and I started feeling sharp shooting pains through some of my teeth that made me want to cry, it was some of the worst tooth pain I have ever felt. I do not know that I will ever use this product again and am glad I could get through the pain of using it this time around.

I was really impressed with the crest 3-D white two hour express teeth whitening strips. I couldn't believe that my teeth could could be cleaned in two hours but it worked great! I have went to the dentist office in the past to have my teeth whitened on a few occasions so I was somewhat leery that this product could compare to that. I was pleasantly surprised. This product is very affordable and has long-lasting effects. I highly recommend this product to people who are looking for an inexpensive way to clean their teeth. Effectiveness I could tell a huge difference after using this product. My teeth were a couple shades lighter than before. When my husband came home from work, he asked me if I had gone to the Dentist to have my teeth whitened. He said he could tell a big difference. Convenience Very easy to use. The strip stayed on my teeth without falling off. I cleaned my house and when I was done I removed the strips and I could see a huge difference. Minimal Side Effects I did not experience any type of side effects. My mouth was a little dry but that was to be expected.

I simply LOVE the Crest 3D White Express whitening strips. For busy parents that are always on the go and just do not have any time for themselves, the Crest Express whitening strips are a lifesaver! I have always used the regular Crest whitening strips and it always seemed that something came up and I could not finish their recommended regimen. With shorter whitening time, the express teeth whitening strips can be used immediately before an occasion demands whiter teeth. The one difference that I have noticed between the express teeth whitening strips and the regular Crest whitening strips is that the first makes my teeth more sensitive to hot and cold foods compared to the second one. So, I have supplemented my regimen of express whitening with brushing my teeth with anti-sensitivity toothpaste before and after using the whitening strips. Overall, however, can't live without the express whitening strips!

I went through years of oral abuse when I was younger. I never really brushed regularly till I was in my mid 20's so obviously I had horribly yellow and stained teeth. Brushing helped a little bit but I still wasn't getting the outcome I wanted so I invested in a month of these figuring I had nothing to lose. They were relatively easy to put on and after only using them for a week I could see the difference. They left a little bit of an unwelcome taste in my mouth so after using them I would wait about 20 minutes then brush. To my surprise they even helped lighten the stains I had. I would definitely recommend these to anyone who needs a quick whiting without the costly price of the professional dentist session. Effectiveness Quickly helps with whitening and even helps with obvious stains. Fast results! Convenience The are relatively quick but I would only use them at home as the urge to brush right after kicks in quick. Minimal Side Effects Other than the lingering taste if you don't brush after, there is no side affects.
