GAME CHANGER — Whiter than my dentist cleanings
Size: 42 Count (Pack of 1)
These whitestrips honestly shocked me. I’ve been using Crest 3D Whitestrips Professional Effects for about a week now, and my teeth are already noticeably whiter—like, dramatically whiter. I get professional cleanings every 3 months, and I’m not exaggerating when I say my teeth look whiter right now than they do after a fresh dental cleaning. A few things that stood out: Fast results — I saw a difference within just a few days, which lines up with claims that results can start quickly No sensitivity (for me) — I was expecting some, but nothing at all They actually stay in place — I can talk, drink water, move around without them slipping Professional-level results at home — honestly feels like I skipped a $400 whitening treatment I’ve tried whitening toothpastes, trays, all of it… nothing has come close to this. If you’re on the fence, just try them. I wish I had done this sooner. These aren’t just “slightly better” — they’re legit next-level whitening. I’m already planning to keep these in my routine going forward.

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.

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.

Works but a little hard to remove
Size: 42 Count (Pack of 1)
They WORK!! Yes, my stained teethe are no more. Just put the strips on and follow the directions. Easy Peesey. It says your teethe will not stain for 12 months. So far it's true. Easy to put on but when removing the bottom strip it can be a little difficult. It was for me. The strips work.

I didn't see not much difference, and I feel pain on my teeth after using this product. I don't recomend it.

So white! Able to get past sensitivity
Size: 42 Count (Pack of 1)
These are amazing! The first couple times I used these strips, I had a horrible pain in my two front teeth about 20 min in and I had to pull them off quickly. I have been using sensitive tooth paste and it has made it a lot more bearable. I’ve used them almost every day the past week and I’m shocked how white my teeth have gotten! Will definitely get them again when I run out for maintenance.
