The product is affordable and very effective in whitening the teeth. Its also very easy to apply and remove

I bought this whitestrips, it is cool. This is one of the most effective whitestrips for teeth whitening. Crest is the best brand if you want to get white smile. And if you want that everybody ask...ohhh..you have so white smile.

So easy and such an obvious difference. Pic at night, in same artificial light, comparing before and after 10 days/treatments (so half of a full course).

On my second order. I get lots of compliments on how bright my teeth are - even from my dentist. So easy to use. I put the strips on just before bedtime - watch a 30 minute program and remove! In addition I use Crest 3D White toothpaste daily.

[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.

[This review was collected as part of a promotion.] The application was super easy—they stuck well and didn't slide around, even while I was multitasking. I kept them on for 30 minutes like the instructions said, and by the time I took them off, I could already see a subtle difference. After the second day, my teeth looked noticeably whiter and just cleaner overall, like I had just come from a dental cleaning. There was a tiny bit of sensitivity, but nothing unbearable. It's such a quick fix when you want to boost your smile fast—definitely something I'll keep on hand for special occasions or when I need a confidence pick-me-up.

[This review was collected as part of a promotion.] I can't believe how unbelievably easy these strips were to use. They gripped the teeth well without moving around during the entire whitening process. I have no issue with sensitivity while using them and they actually worked in whitening my teeth like they were supposed to. I would definitely use these again in the future as I really like the overall results.

May I know why there's an uneven whitening after my first use of 3D professional effects white stripes? Should I continue or stop using the remaining white stripes? Hope to get your reply soon.

[This review was collected as part of a promotion.] These whitening strips were really no good for me. I have sensitive teeth and avoided strips for that reason but when I saw these were specifically made for sensitivity I was excited. Well my teeth hurt. I tried the strips numerous times and every time they left my teeth in pain for hours. Past that the strips were horrible to try to keep on properly. I did noticed a smidge of whitening from the times I used them so on that front I'd imagine they work okay. But due to the pain from them I won't be purchasing or using the rest.
