I use Crest 3D white luxe glamorous toothpaste and I must say it works wonders. I was using another brand's toothpaste that was alleged to whiten your teeth but instead what it did was create dark lines on my teeth. Once I started noticing the lines I switched to crest 3D white luxe and I noticed it removed the dark lines on my teeth and my teeth were looking whiter. If it weren't for this toothpaste, who knows how my teeth would look, I highly suggest this product!

Amazing lack of instructions. No where on the packaging, or in the provided literature, do they tell you which strip goes on top and which on the bottom. The strips are not the same length or the same width, so you’ll have to guess which one goes on top or bottom.

[This review was collected as part of a promotion.] I received a free full-size box of Crest 3D White Strips from Influenster in exchange for my honest review! these white strips claim to lighten your teeth by 12 levels in three weeks… I’m not sure about that but I definitely noticed my teeth look whiter and I’m very happy with the results! They’re easy to use! I use them in the evening while I’m watching my show. They stick on my teeth pretty firmly and I just keep them on for 45 minutes. The only downside is that a little bit of foamy-ness and spit accumulates in my mouth while I’m using them so I have to constantly spit that out. Other than that… worth it for white teeth!

[This review was collected as part of a promotion.] We love the comfort, sensitivity and packaging of these white stripes. They do a good job at biting our teeth quickly and effectively. The value is great because you can do that. I’m at home and it cost way less than going to a professional.

I was so excited to buy my Crest 3D whtie strips. I did exactly as the instructions said and I was so disappointed. So all that money down the drain. I'm happy for those that received good results but I think Crest should stand behind the product when it does not meet the expectations of it's customers, namely, me. :-(

[This review was collected as part of a promotion.] I recently tried the Crest 3DWhitestrips Professional Effects, and I can honestly say—they live up to the hype. I started seeing a difference after just 3 uses, and by the end of the 20-day treatment, my teeth were visibly whiter—like two shades lighter at least. Each strip fits well and stays in place (upper and lower), so I could still talk or move around without it slipping. It gave results similar to what I’ve gotten from in-office whitening—without the high price tag. I was worried about sensitivity, but I only had mild tingling once or twice. I used a sensitivity toothpaste during the process, which helped. If you have very sensitive teeth, start slow—maybe every other day—just to be safe.

I've been using crest 3D Whitestrips Professional Effects on and off for nearly a year now and received better results than I had expected! However, the last box I purchased left me more than disappointed. Nearly half of the strips were damaged and unusable, almost as if they were damp when sealed in their individual packages. Major disappointment, but definitely won't keep me from future purchases.

Crest professional effects is so easy and it whitens incredibly !!! I always get compliments on my white teeth and when I tell people that it is from crest whitestrips they are shocked !!! It looks like I got them professional done !!! Awesome product !!! Worth every penny!!!

After 4 long years with braces I finally took them off a couple months ago. I thought I was going to have that wow factor but I didn’t really get it. After applying the 14 day crest 3D white, people started to actually notice my braces were off! My 3D smile made me the happiest guy alive!
