  • THE best crest whitestrips I've ever tried
Size: 42 Count (Pack of 1)
These are without a doubt the most whitening/brightening whitestrips I've ever used. The strips are so uniform and the whitening ingredients are so well spread onto the strips it's crystal clear.I've been using crest whitestrips for 14-15 years now. I started all the way back before the non-slip was even invented and you'd have to just kinda bite down on your teeth to prevent them from sliding around. They've been VERY effective in the past, which is why I've continued to use them throughout the years, but this pack right here is the most effective one I've ever used. I'm only halfway done with the set but my teeth are OUTLANDISHLY white. I started getting compliments from coworkers my 3rd day in. I did some research after buying them because I wanted to know what made these different, and it turns out it has the highest hydrogen peroxide concentration from all other strips out there. Their other strips contain 3.5%, 8% etc, this one's supplying the highest concentration you can get. I will say, if you're new to whitestrips they work by oxidizing the surface of the tooth to remove the stains soaked into the teeth. It's enamal safe, but you'll notice sensitivity. By day 5 I had to go out and get some sensodyne . If you're having sensitivity issues, I recommend getting sensydne and when you go to brush your teeth, spit out the toothpaste, not rinse. When you go to bed, brush softly and spit out the toothpaste, go right to bed and the floride toothpaste will help stick to your teeth and stop that sensitivity. ... show more

  • They do a great job whitening my teeth at age 73

  • It works, but I don't know if I would call this 28-shades brighter.
Size: 42 Count (Pack of 1)
This product does work, so that's great. Your teeth will be whiter. As you can see in my before-and-after photos, my teeth were pretty yellow. I was very self-conscious about smiling, but now I'm not. So that's amazing. However, for a product that claims to make your teeth 28 levels brighter, and make them "supremely white," I don't know if it quite delivers on that. I also am not sure how long my teeth will stay white for, because I am writing this review quickly after using up the whole container of strips. The product description says this should only be used once per year, but who knows if my teeth will stay white for a whole year. I have heard from other sources online that this type of product works better on someone who is a teenager or in their early twenties. I am in my early thirties. Keep in mind that your teeth will be sensitive and in some pain for maybe about 12 hours after each time you use the product. It's not unbearable, but it is annoying, and you will have to get used to it until the end of the month when you have used up all the strips. ... show more
