Crest 3D Whitestrips with Light, Teeth Whitening Strip Kit, 20 Strips (10 Count Pack)

Great product! My teeth were already white but I notice my teeth were brighter before the 7days was up! It’s very easy to use. I’ve use the strips alone before but with the light, it just takes it up a notch. My dental hygienist even noticed a difference! 😁 I will definitely buy again. This product is a definite MUST BUY!!

Got my teeth professionally whitened with Zoom. 72 hours after avoiding coffee and eating an all white foods diet, my teeth returned back to yellow much to my complete despair. (Goodbye $350!) decided to buy these strips. I use them for a week, hour each, and got modest results, I’d say my teeth got 25% more white, which was GREAT but I decided to buy Opalescence 35% gel to get quicker/stronger results. Got GREAT results on my first syringe - decided to take it up a notch and put one of these crest white strips on top after the Opalescence to really try to increase the brightening effect… y’all.. the result where SHOCKING. My teeth were about 80% of the whiteness that my dentist got.Now that I’ve used up all of my Opalescence gel, when I want to touch up my teeth on sundays I use two crest strips but I instead back to back (2 in 2hrs instead of 1 for 1 hr) and it brings my teeth to a bright white and lifts away any dingy yellow stains.This product is good for someone who already has off-white teeth that needs a bit of brightening. But if you have super yellow teeth like I did, #1 don’t expect miracles - and don’t bother with this STUPID light - research shows light is only effective with HYDROGEN peroxide (this is carbomide peroxide) and further more, these lights increase the risk of increased teeth sensitivity and INCREASE the risk of oral cancer due to the harsh blue UV light on gums which are already being battered by peroxide (which in itself is already cancerous in nature) so just skip the light. And #2 if you’re going to use these, do yourself a favor use 2 at a time for MAX RESULTS. Even better if you use 1 after a Opalescence treatment. Try not to drink coffee or eat bright foods & spices (turmeric, paprika) no chocolate/berries for 1 day. Saliva seals the dental pores after carbomide peroxide whitening in 2 hours, but if your teeth aren’t 100% mineralized then it can take longer/prolong risk period of restaining.Lastly. STOP USING FLUORIDE TOOTHPASTE! I am certain this is what made my teeth yellow post whitening procedure. I Did research, turns out there’s tons of articles and research studies that prove fluoride in toothpaste YELLOWS TEETH from the inside out by oxidizing the dentin! CREST even admitted it!! Talk about selling a problem and selling the cure, BIG SIGH. After changing my toothpaste to nano-hydroxyapatite (a natural more effective, NON TOXIC alternative to fluoride toothpaste), I have no more sensitivity, teeth have gotten WHITER & parts of my enamel are LESS CLEAR!!!

Si me blanqueó los dientes. El trátamiento es de una hora, un poco incómodo porque no puedes beber hablar y comer durante esa hora pero si me gustó los resultados.

I drink a lot of coffee. My teeth are white again. Yay

This stuff is a game changer. My teeth looked whiter after one use

My experience:Personally, I used this precisely as directed for ten consecutive days (no coffee, no smoking, no soda, brushing twice a day, using whitening mouthwash), and you can see in my attached pictures that the change, while non-zero, is nothing to write home about. The kicker for me was the sensitivity that the treatments caused, which was relatively mild but certainly noticeable. I'm vexed by the testimonials of some of these other folks - though, of course, I am happy for them!The only reason I could think of that it may have been less effective for me, would be if brushing one's teeth after the treatment would somehow impact the results, as I did this a few minutes after each treatment - followed by a rinse with Crest's whitening mouthwash. However, per Crest's own site and instructions, this should be fine to do (and the mouthwash itself even claims a brighter smile in seven days).A word to the wise:Upon closer examination (after purchasing) of some of the before/after photos that had most convinced me, I noticed that the lighting in the 'after' pics were generally brighter / cooler, which would exaggerate results - you can discern this by looking at the skin tone in each photo. For this reason, I used the same location and lighting for my progress pictures to be able to leave an accurate review.Conclusion:The product by no means matched my optimism, but others happily seem to have had a very different experience - so if you have ~$70 of comfortably disposable income, I wouldn't seek to stop you from giving it a whirl. At worst, you'll have middling results like mine, with some tooth sensitivity (which will likely go away within a week) - and at best, you could be one of the lucky ones with a dramatic transformation for some reason! Personally, I'm going to try Snow's whitening kit next, with the hopes that those results will justify the steeper price. If you've not heard of it, you may want to look into that as well - though I can't yet vouch for their product from my own experience.Best of luck to you all in your whitening endeavors!
