This strips are amazing. I definitely see results whenever I use them. I tend to get a bit of sensitivity, so I just use them every other day and the results are still amazing.

The best toothpaste I ever used if u Want white teeth use other products if u want the best teeth a person ever seen use 3d white it really helps I mean a lot and 3d white is like the best I ever used

This is by far my favorite whitening strip. I have noticed a difference in my teeth being whiter. Only thing is don't leave on for too long or teeth become sensitive.

This product is good. It's real and noticeable. Not magical. I recommend brushing your teeth extremely well and “drying them” prior to application. Don't overdo the time and don't use them all the time. But yes good investment for sure.

These things work. That's all I have to say! No issues whatsoever. Maybe a TINY bit of sensitivity...but I have that anyway. I noticed a difference in like...a week maybe? Would definitely use these again.

MY FAVORITE! Using this before I brush my teeth while I shower is the best way to start my day. I feel so confident with white teeth and these really get the job done!

I hate the way these feel in my mouth but they definitely do the trick to temporarily whiten teeth before a big event. Make me feel more confident in those scenarios or with a lot of photos

My teeth are a little too sensitive for these. Use them and my teeth hurt for a few days. I've used their Gentle Routine strips, and they work better for my teeth.

Yes this product did whiten my teeth a little. It was totally not worth it though! I barely have sensitive teeth, and the morning after I used them I woke up in so much pain! I wouldn't reccomend this product at all.

Crest 3D Whitestrips are the best...I've been using them for a few months now, and my teeth are beautiful... I receive compliments from my students every week!
