[This review was collected as part of a promotion.] I recently tried the Crest 3D Whitestrips Rapid Smile Makeover, and I was genuinely impressed! The packaging is sleek and easy to use, and the strips stayed in place comfortably without slipping or feeling bulky. I noticed a visible difference in just a few uses—my teeth looked noticeably whiter, and the results felt professional. I have pretty sensitive teeth, but I experienced minimal sensitivity with these compared to other whitening products I’ve used in the past. For the price, I think the value is amazing—quick, effective, and perfect for a last-minute glow-up. Definitely a staple in my self-care routine now!

I purchased the Professional grade strips in hopes that they would brighten my smile a few shades, but after using them for nearly 4 weeks, I've not seen a significant improvement. I had high expectations based on some of the reviews, but unfortunately, these fell flat along with my smile.

[This review was collected as part of a promotion.] I’m no stranger to white strips. I usually use the sensitive teeth version, but the results with those are pretty meh. I’m happy to say these Crest Whitestrips didn’t make my teeth super sensitive. I used them every other day as opposed to daily to be on the safe side. Not perfect, but I’m happy with the results considering I’m a coffee and wine drinker and spent 4 years in braces (which does a number on you). Would def purchase this product!

these strips changed my entire life. my teeth used to be YELLOW they are now as white as computer paper. every 6 months I get a new box even though I don't actually have too. your teeth will stay pretty much white for probably over two years. I like how they look right after or during a box because they are sparkling. if I could post pictures I would. awesome.

I have used these before and they have always worked. However, this last purchase does not work. I was send old out of dated ones that have no stick to them at all. I ended up throwing them out. What a waste of money. I will never purchase from these people again

I remember using Crest Whitestrips back when they first came out. Completely satisfied. This time around not so much, which was a disappointment since I expected similar results. After the first box did not work, I decided to go ahead with getting a second box through Crest, as recommended. I used the product 30 minutes once a day, and did not use immediately after brushing, as recommended. It did make some difference, but my teeth still have a yellow tint.

[This review was collected as part of a promotion.] As a coffee drinker and smoker, i don't have the best-looking teeth I'm ashamed to say 😔 but these Crest 3D whitening strips have made a difference! This was only over 10 days! I love the difference it has made, i smile more with my teeth and feel more confident!

So I bought this because I was desperate for whiter teeth, although I don't drink coffee at all, I had yellowing to my teeth. Sadly, after using this five times, not only do I have teeth sensitivity (which is fine because I expected it), I also have spots on my teeth that appear to be whiter. It doesn't seem to be overall whitening my teeth as much as it's just whitening certain spots more than others.

This is my third usage in 10 years. I am happy each time. I also am blessed with unnaturally white teeth and the contrast to my skin colour helps :) Most people make the mistake of NOT using the strips consecutively and therefore the results are not as great.

So basically a bad depressive episode caused me to neglect my teeth and then endless amounts of coffee didn’t help. After working myself out of it and finally taking care of myself, I still couldn’t smile with my teeth. I was self-conscious. I thought about getting them professionally whitened but opted to try this. BOY. I saw results by the third day like the box said I would. By the fourth day, I could almost cry. I’m not done with my 20 treatments yet but this has seriously changed everything. It makes me so happy. I can’t believe I could have just done this the whole time. Thank you crest, for this lovely product and giving me my smile back.
