Every time I feel the need to whiten my teeth I always go back to this product. It does the job really well. It’s a little pricey but so are most at home whitening kits/strips. Although it’s pricey it does give you a lot of strips. My only issue with them is that they taste kinda gross. However, I could tell the difference in color of my teeth just after one application.

I have been using crest white strips for about 2 years now. I used to smoke cigarettes & I am a big coffee/tea drinker. These have been a complete lifesaver! I was embarrassed about how my teeth had a yellowish tint. After a whole box of strips, over a couple months I was finally so happy about how my teeth looked. They are so pretty & white. I get compliments all the time on how beautiful they are. I would 100% recommend these to anyone that wants professional results without spending thousands of dollars :)

Love these whitening strips! I do not recommend using twice a day if you have sensitive teeth because they can cause some pain. I also don’t suggest doing it that frequently if you’re teeth aren’t extremely yellow bc they may turn transparent. I use as needed and they keep my teeth white!

I always have a box of these handy! I really enjoy how simple it is to use this product. No need to hold a light up to your mouth or use messy charcoal powders. This product is two sticker like adhesive that you place over your teeth and leave on for about 30 minutes. I only give it 4 stars because it makes my teeth sensitive for the day.

So these definitely work great but the using part is a bit tricky. They do not stick well to your teeth and generate a lot of spit. I highly recommend taking a towel and drying your teeth before using to aid in the stocking. But trust me they work you just have to deal with the small hassle of using them.

I just recently started using these and I’ve only done it a couple of times but I haven’t had any problems with it. I haven’t seen any clear results but I’m giving it some time to work. Overall, it seems like a decent product but clear results aren’t quick.

Expensive and uncomfortable...have to put those strips and endure an hour of disgusting foam in my mouth everyday. The strips are made small now so they have trouble sticking to my teeth...i can see them slightly whiter but not worth the trouble or money

Ive been using Crest Whitestrips for years (Advanced Seal) and always noticed a huge difference. I received soo many compliments and people were always asking me what my secret was. I recently used the entire box of Professional Effects (Luxe) and honestly so no changes. Not sure if there was any change in the formula but i am a bit disappointed. I still think its a great product however and should definitely be given a shot

These work very well. They are super easy to use and quick as well! Some people have sensitivity when using these whitenening strips, but I did not. The only time I had sensitivity is when I did two treatments in one day (and it hurt), so I recommend sticking to one treatment each day. Pretty expensive but worth it.

This product had good reviews, so I decided to try it after getting my braces off. I used as directed for over a month, and did not notice any difference. In addition to this, it also makes my guns feel itchy. I look forward to trying some alternatives.
