Product no longer as effective.

Definitely not as effective as the product used to be. I have used Crest whitening strips for almost 15 years and always saw great results even after just 3 or 4 days of treatment. (I usually whiten my teeth only once per year). I just bought this pack of Professional Effects and have gone through the full treatment and my teeth still look slightly yellow. Clearly Crest has reduced the quality...like every other company out there today who rips people off with 'shrinkflation.' Really disappointed.

It really works!

I used this product after noticing my teeth were stained from smoking and drinking dark sodas. It really works great after only about using three strips I noticed a huge difference of about three shades. After i was done with the entire treatment I would say i've went 5-7 shades whiter! I use these every month once a month to keep up the whiteness and its great everyone notices how white my teeth are now :)..... I would recommend these to everyone!! XOXO

I'm In Love!!!!

I've never seen anything work this well on my teeth! At first I'd lost hope and believed that my teeth would never become white but after using Crest 3D white strips I was given a healthy, clean, and sparkly smile. For a professional smile, get Crest 3D White Strips and you'll never be disappointed.

results within one use!

I've tried everything to get perfect white teeth! My teeth were always a light yellow color, I never wanted to smile with my teeth I was so not confident with my teeth. So i decided to buy the teeth whitener. Best purchase I have ever made! Now I can be happy with my smile. And very confident. I get compliments all the time now about my teeth, and about what I did to get them so white. My answer is, "Crest 3D whitening strips!"

This product provides results but leaves your gums feeling so sensitive! The next day my gums ache and its a very uncomfortable feeling. Ive been searching for alternatives. I also dont like the actual application of the products I think a gell pen works better and less sensitive

These whitening strips work really good!!! I love how I use them on the go! When I’m in a car driving to work or on the train even! It takes 40-45 mins to kick in and give you the nice white teeth! As a dental professional I recommend use these strips 1-2 a week for 30 minutes! Your teeth will become Snow White! Give it some time :)

I love the crest whitening strips so much. You notice improvement within the first use! They are gentle and effective. Within several uses you have a brand new smile. These play a major role in the confidence I have with my smile. I would recommend this to everyone.

I stand by these strips for my teeth! I whitened them about 10 years ago and just barely had to touch them up again and go in. I constantly got compliments on how white my teeth are. Personally I didn’t suffer from sensitivity. Also it lasted so long because I didn’t drink soda, coffee or wine! So just be smart on what your eating to prolong the results, like with any other teeth whitening products!

Worth a try

[This review was collected as part of a promotion.] I have always wanted to try these white strips but I realized they weren’t right for me. I have gone to get them professionally whitened about three times and have always experienced extreme sensitivity pain afterwards. With this product I have to wait 2-3 days until the next dose due to pain. It is simply not worth it for me. I rather get instant results one day and take pain pills instead of these week treatment. If you don’t have my issue you should give these a try they are reasonable priced and are easy to use and after using it for a week I did see my shade 1 shade brighter or at least a slight difference.

These hurt my teeth terribly, so I can’t use enough of them to tell a difference. About 12 hours after I use one, my teeth start to throb some. To be fair though, I have some damage on my teeth from drinking a lot of sodas as a child. Would love them if I could use them! They stick to your teeth very well and don’t have a bad taste.
