These work just as well as a professional whitening... Easy and worth the work! Only negative thing I have to say about them is that my teeth have gotten more sensitive.

This product delivers on its promise. When used as directed, it whitens your teeth without causing sensitivity. Results are noticed quickly. I like to use twice a year but sometimes the whiteness lasts longer!

These stick to your teeth and only come off when you’re ready to take them off. They’re a good confidence builder if you want to add an extra sparkle to your smile! They are awesome and whiten with consistency

definitely a progressively slow whitening kit but i can for sure tell a small difference after using for about a week. they just stick to the teeth too much though and i have to peel them off with my nails.

While these are effective, they are super painful. My teeth become incredibly sensitive when using them and as a result I can never follow through with a full treatment. I wish they could make these a bit more bearable because they’re so convenient

Love these but if you aren’t careful and get the strip any where on your gum, it can become sensitive. My mouth definitely bothered me for a FEW DAYS after I realized my mistake but other than that super great and flawlessly white teeth!

These work really well. I have to space them out because my teeth do get very sensitive after use. But they certainly make teeth whiter and they stay on well.

I do love these whitening strips but like most whitening products, they make my teeth super sensitive. After using these my teeth are noticeably whiter though so I do still like the product I just already have sensitive teeth

These are amazing! They work super fast and don’t make my teeth sensitive. 10/10 would recommend- I am a big coffee drinker and these make a huge difference.

The RESULTS that I’ve received from Crest whiting strips is absolutely astonishing! Although they’re a little on the pricey side, they are definitely worth the price tag! I’d definitely purchase this product once more in the future!
