Crest 3D Whitestrips Age Renewal – Teeth Whitening Kit, 24 Treatments (20 + 4 Bonus), Each with 1 Upper/1Lower, 48 Strips – Crest 3DWhite Teeth Whitening Strips

Earthlings, if you're on a quest for a grin that could outshine the stars, hitch a ride with Crest 3D Whitestrips Professional Effects Plus. Here's why these little strips of science are more than just a fleeting comet in the dental cosmos: Ease of Use: Applying these whitestrips is as simple as navigating through the less complicated parts of the galaxy. Stick them on, and they cling like a scared barnacle during a space storm. No slip, no slide, just a firm grip on your quest for whiteness. Effectiveness: After just a few uses, your teeth might just start reflecting light in ways that could confuse passing UFOs. They promise professional-level whitening, and by the rings of Saturn, they deliver. Expect your teeth to jump several shades whiter, assuming you're not starting from the darkness of a black hole. Taste & Comfort: The taste isn't gourmet space food, but it won't make you wish for an alien abduction either. The no-slip grip means you can talk, drink, or ponder the meaning of life without them budging. However, if your teeth are the sensitive type, prepare for a bit of a zing - think of it as your teeth's way of communicating, "We're getting whiter!" Time Commitment: You're signing up for about an hour per session if you include the express treatments. Perfect for when you're binge-watching reruns of 'The Expanse' or contemplating the vastness of the universe. Price: At roughly $50 for a set, it's cheaper than booking a seat on the next commercial space flight for a closer look at the sun to check if it could bleach your teeth. Plus, they often come with bonus 1 Hour Express strips, because who doesn't like a little extra thrust in their whitening rocket? Packaging & Environmental Thoughts: They come in less packaging if you choose not to have them re-wrapped by Amazon, which is good. Less waste means more resources for Earth, which might just make you smile brighter. Conclusion: Crest 3D Whitestrips Professional Effects Plus are like having a mini dental cosmos in your bathroom. They're not just good; they're out-of-this-world effective for at-home teeth whitening. Sure, they might cause a little sensitivity, but what's a little discomfort in the pursuit of a smile that could potentially signal spaceships? So, if you're looking to give your smile the gravitational pull of a small planet, these whitestrips might just be your ticket to interstellar dental fame. Just remember, while they can make your teeth whiter, they won't help you speak alien languages. For that, you'll need another kind of strip... or maybe just more practice with your universal translator.

It's Crest - so still the best of the whitestrips. Work fast and easy. A regular fan of the product.

Works very well BUT in my experience it is far more difficult to keep strip for bottom teeth in place. No problems getting top strip to remain. Maybe there is more moisture in bottom part of my mouth ? Anyway, a challenge to keep bottom strip on my teeth. Had to ‘give up’ a few times and just use top row strip.

Great value in these. They work very well and I notice a difference immediately that my teeth are whiter

I could see a visible difference within 10 days. No issues with sensitivity. Only half way through the 24 day treatment, but it’s already working and worth the money.

I’ve been using the Crest 3D Whitestrips Age Renewal kit for a couple of weeks now, and the results are definitely noticeable. My teeth look brighter and cleaner, and even after just a few treatments, there’s a clear difference. Each packet comes with one upper and one lower strip, and they stay in place really well — no slipping or sliding while you’re wearing them. I also like that the kit includes 24 treatments (20 regular + 4 bonus), which makes it a great value compared to other whitening options. One thing to note: if you have sensitive teeth, you might feel a little tingling at first, but it goes away quickly and hasn’t been an issue for me. I just make sure to space the treatments a bit if needed. If you’re looking for an effective, easy-to-use whitening kit that delivers visible results, this one is worth it. ✨🦷

The packaging is almost borderline infuriating. The precut sections never let you completely open the strips packaging cleanly. It always veers off to the side. And both sides of the strips are identical. So you have to pick and pry at both sides to see which one has the removable section. The top tooth section is long, skinny, and narrower compared to the much wider, shorter bottom tooth section. The top section covers more teeth and actually sticks well. The bottom section only covers the front of your bottom teeth and it always slips and slides. Pretty frustrating. They feel awkward in your mouth. Especially in the areas they tuck behind your teeth. It's hard not to rub your tongue against them. They taste like hydrogen peroxide marinated plastic, so there's that. With all the hassle aside, they do work. They have removed a terrible coffee stain from my front tooth. Both times I've ordered I recieved the express strips. It's ironic because the express strips require an hour of use versus the standard 45 minutes lol. Express whitening? Not sure. They seem to work as well as the regular strips. I use them every other day to avoid sensitivity. They don't really hurt my teeth, but they do hurt my gums a little bit. All in all, they are tricky to open and use. But they work
