These taste a little weird.... but I love the end results, my teeth get so white and it is fun to use

I will forever swear by these. Great product. Teeth were visibly whiter after one use. Does make your enamel a little sensitive but to be expected.

These things WORK!...I just hate how it tastes and feels in my mouth...and too much use can cause tooth sensitivity.

The results are there. However, my teeth get really sensitive after use. After a day the sensitivity goes away.

This stuff is amazing 👏 it does exactly what it's supposed to do! I recommend it to everyone as well as the whitening strips.

I purchased these because after trying a sample that proved that they worked I was satisfied with the results.

Easy to use! Was able to control when the teeth became sensitive, i just stopped for a day then continued on.

I have been using this product for over 10 years. The professional effects are worth the money because they provide high quality results.

Love them when I need a whitening boost! They are pricey but are worth it if you're into oral hygiene, and definitely not for everyday use.

No better brand than crest for teeth strips. Don't irritate my sensitive teeth too much but still get the job done
