i like these but they make my teeth sensitive and also it feels kind of weird to have it in your mouth for so long, but i do notice visibly whiter teeth and i prefer this to dentist whitening

These made my teeth very sensitive. They do whiten but I had sensitive teeth for a week. I would not use them again. But if you’r teeth don’t get sensitive they are great. 

Love this product! It is so simple to put them on and lay back and watch a Netflix show. set your timer then take them off, it’s as simple as that. They really whiten your teeth if you stick to it. I would recommend to everyone!

I’ve use this product a couple times and I am definitely not impressed with it at all. The strips did not want to stay on and I never saw any results.

These make my teeth noticeably whiter! I love the results that I get. I personally think I would use a tray or something because the strips tend to slide around sometimes and it’s hard to put back in to place.

Crest 3D whites has flipped my world upside down. There is absolutely no need to go to the dentist and pay for expensive treatments when you have this product! The change is instant and is inexpensive! I am a satisfied customer!

It did make my teeth a little more sensitive but not a lot. I noticed a difference in my teeth being whiter however it wasn’t that great and some people’s

Unfortunately these did nothing. I did have some slight sensitivity here and there. The last kit that I used wasn’t directly from crest do I thought maybe that was the issue but this kit didn’t work either.

I love this product I only have to use it a few times a year and my teeth are sparkling white. My dentist actually recommended these rather than getting a harsher whitening treatment

I get asked ALL the time, how do I keep my teeth so white and this is it!!! I have never had a dentist whiten my teeth and as long as this stuff is around, I never will!!!
