Crest Whitestrips Pro Effects,10-Day Dental Whitening Formula System, 40 Strips (Packaging May Vary)

Comment: There's a reason why curiousity killed the cat... I read all the reviews on all these crest whitening products prior to my purchase... Being curious, price conscious and wanting the best bang for my buck, I bought these crest white strips... I can tell you that I'm not impressed! Prior to purchasing these, I have used the equate Walmart brand in the blue and white box, 56 strips I think and they run about $18.00, so I have something to compare.

1. The biggest pain with these crest strips is that they are very thin, flimsy, they tear very easily and they move all over your teeth even if you press your lips down on them from the outside of your mouth.

2. I hardly saw a difference after using these crest strips, every single time I used the walmart strips, I saw white and about 2-3 white spots on my teeth immediately after every use. The white spots are small, normal and they go away within a short amount of time. Btw, I have fairly nice teeth, not bright bright white but not all yellowish either... Maybe a 6-7 out of 10 whiteness.

3. With these crest strips my lips became dry, sticky and my teeth hurt for a while after every use, even during the night. I rarely felt tooth sensitivity with the walmart brand.

All in all, they are both suppose to do the same thing... Whiten teeth! The walmart brand strips are a little bit thicker but easier to use in my opinion and they stay put, crest says your able to be normal, talk and enjoy life with theirs on... hogwash!! When I put on any whitening strips, I'm at home watching TV or on the computer and the last thing I want to do is have a conversation with someone! 30 minutes flies right on by and then I do another 30. I have nothing against crest, I just think they put more effort into marketing their nice oversized blue plastic box rather than making a better whitening product! If it looks good, people will buy it... That's Corporate America! I'm sooo glad I didn't pay the rediculous price they want in the retail stores!!! I will not be buying these again. Hope this info helps...

Comment: I am 21 years old. My teeth are a little dingy and yellowy, so I decided to try a cheap solution. BAD IDEA.

I followed the directions and after the first use, after just five minutes, I felt a horrible sharp pain in one of my teeth. The box warns against "tooth sensitivity". I didn't know that terrible achy/sharp/electrified pain fell under that category. My teeth still hurt. I feel like I have a hundred rotting cavities right now. I guess my tooth enamel is in really bad shape or something. I can chew ice and drink hot beverages without pain so I assumed my teeth were reasonably strong.

This product is not for everyone. Unless you have mega tough bad-ass teeth, I recommend you try a milder tooth whitening option.

I remember trying whitestrips when they first came out and they didn't cause me pain. I think this is has the highest peroxide level of all the versions, so that is most likely my problem.

I am definitely not risking the pain again with this genre of DIY Dentistry. I hear medieval nobleman would gargle with their own urine to produce a whitening effect....mmmm....urine.......I wonder if it qualifies for Amazon Prime?

Comment: It's hard for me to tell if these strips did any good (that should say enough), but they also didn't stay in place very well. They slipped around and made it awkward to speak with family (who said I sounded like I had a lisp). The strips are two different sizes, one for your upper teeth; one for the lower, but the one for your lower teeth was fatter (it should have been longer) and merely covered behind my teeth too (uh, I don't need white teeth where only my tongue can see them!). My suggestion to Crest: make both strips the same length and width.

Comment: it works, make sure you stick to it becuse i forget sometimes. at night i try to wear it to bed. pls do not wear it to bed cos it make your teeth/gum sensitive.

Comment: I've seen results very quickly with this product, but I'm disgusted at the packaging that Crest uses. The whitestrips are paper thin, yet the box the come in is enormous. Not only is the box 3x bigger than it needs to be, but it's double-walled plastic, doubling the waste!

As much as I'm impressed by the product, I cannot recommend it based on the packaging waste.
