I've used these for years and honestly they never fail to make my teeth look flawlessly white. It lasts for a couple of days, and I skip a few days in between but I love it. I don't use them very often due to having sensitive gums but find that 1-2x a week is perfect to avoid increased sensitivity!

The crest 3d white strips have been the amazing key to my beautiful bright smile. It is my holy grail. Whenever I have a special occasion or an important meeting to attend, all I have to do is slip these on my teeth for about thirty minutes and BAM! I feel confident and glamorous . It is worth every penny!

These are the only teeth whitening strips I have ever used which is why I am rating it a 4/5 because I don't have much to compare it to. However, I am super impressed with how white my teeth look when I use these and the only complaint I have is that sometimes the strips with make my teeth a bit sensitive. Even though these are kind of pricey they are totally worth the money and I love them!

I love these whitening strips! They work very good! I use them everyday! They are a bit pricey but In my opinion they are worth every penny! The pros are they leave your teeth so white and it last for a while. The only cons I have is that if you have sensitive teeth it can make them more sensitive the first couple of times using them.

Not comfortable at all. The strips slide around so you have to make sure you're not really doing much, and makes me roam at the mouth a bit (lol) always quit before using consistently because of the discomfort so I'm not sure how well they actually work

I know a lot of people have talked about this product having the possibility of ruining your enamel and making your teeth more sensitive, but coming from someone who has both sensitive teeth and gums, this product gave me 0 problems and 100% satisfaction. It is definitely on the pricey side but one box, or at least 10 treatments will hold you solid for a long time. It's a great investment and made me all the more comfortable with smiling!

The new crest professional white strips are the best thing ever made!!! I noticed a change in the color of my teeth within 3 days.My family & friends all noticed & asked what I was using.They are so easy to use & they stay in place & do not slide off.I can not believe how well they whitened my teeth.

Love these!!! They work extremely well I always have a noticeable difference after one use!! Great quality product with trust worthy ingredients that won't harm your enamel on your teeth. I started out using the OG crest white stripes and now use the professional effects. I highly recommend these!! Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

Crest has been whitening teeth for a long time! Of all the at home treatments, Crest seems to be the best. While it can be expensive, it's a lot cheaper than having your teeth professionally whitened. My dentist actually recommended trying crest whitening kits before paying for professional whitening.

I love this whitening strips they really help my teeth bring out their natural white pearly color they're a little bit pricey but I totally recommend them the value is higher than you could imagine I would recommend this to anyone who needed white teeth
