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.

These work really well. I’ve always been skeptical of the strips and never wanted to take on the expense of professional whitening, but finally decided to try them… 22 years after I quit smoking. They can be tricky to keep straight on your teeth, so make sure you suck in some air to dry your teeth before applying them. My teeth haven’t looked this white in years. I’m VERY happy with the results.

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

I will start by saying that although I was expecting some sensitivity issues (I read a lot of reviews...) there has been none until now. I did start brushing with Sensodyne Rapid about two weeks before starting the white strips, and I continue to brush with it right after I remove the strips. I have also been using Sensodyne Protect & Repair with Novamin. I just removed my 4th pair of strips and to be honest I don't see a difference... My teeth are still as yellow as before. I don't smoke or drink coffee/wine, so I guess it's just the quality of my enamel. I really was not expecting a drastic change, but after 4 treatments I thought there would be a little improvement.... I don't know, should I still be hopeful? Now, about the infamous bottom strip: dear sirs at Crest, the bottom strip in the Advanced Vivid is ridiculously small! I mean, seriously, who wants to have six beautiful whitened teeth sitting right next to two or three yellow ones?? It shows! No one has such a small mouth. I had to use one packet of strips just to cut into pieces so I could cover the other teeth, which in my case are the darker ones. So, I'm already down one treatment. Other than that, the advanced seal works very well, the strips are easy to apply and remove and leave no taste in my mouth. No sensitivity in the gums either. Now my question is what white strips version should I try in case these do not work at all, and how long should I wait inbetween treatments? I would really like to get rid of some of this yellowing... Can you help me Crest? I will come back and update this review towards the end of the treatment. Keeping my fingers crossed! Edit Day 5: I left the strips on for one hour this time, although it is not recommended and Crest does say the product won't whiten past the recommended time. Sure enough I still can't see any real change in shade. The teeth look whiter right after I remove the strips, but after a few seconds the color is back to normal. I did experience a few twinges on my teeth about 8 to 10 hours after this treatment, nothing painful, just weird. I guess leaving the strips for longer than recommended does improve your chances of getting sensitivity. Still not impressed. Edit Day 6: this time I went back to the recommended 30 minutes routine and the slight sensitivity didn't come back. I have finally started to notice a difference in teeth shade, they are not much whiter (maybe one shade whiter) but they are definitely brighter! Also I went to the dentist and had them professionally cleaned, I hope that helps a little with the process. Edit Results! I can now say that my teeth are much whiter and I am so pleased! Still a few days to go so it can only get better. It took me about six days to really start seeing a difference but these actually really work, it's worth the wait. I'm rating these strips 4 stars just because of the size of the bottom strip. Other than that they work great and gave me no pain or discomfort.

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. ✨🦷

When you apply them, brush your teeth well than dry your teeth front and back good with a tissue.. This helps a lot with them staying in place and adhering to your teeth. If there’s moisture on your teeth this is where the problem comes from when applying. Hopefully this is helpful to the people that have trouble with them staying in place.

I’ve been using the Crest 3D Whitestrips Age Renewal – Teeth Whitening Kit (24 treatments + 4 bonus) and I’m honestly blown away by the results. After just a few days, I noticed a visible difference—and by the end of the full treatment, my teeth looked several shades whiter. 💬 What I Love: • Professional-level whitening: Removes deep-set stains from coffee, wine, and age-related discoloration. • Easy to use: Each strip sticks well and stays in place—no slipping or sliding. • Fast results: My smile looked noticeably brighter within the first 5–7 days. • Bonus express strips: Great for a last-minute boost before special events. ⚠️ Small Downsides: • Some mild tooth sensitivity, especially in the first few days—but nothing major and it faded quickly. • Make sure to avoid your gums when applying to prevent irritation. ⸻ Final Verdict: If you’re looking for a powerful, at-home whitening kit that really works, this one delivers. The Crest 3D Age Renewal strips are strong, safe, and super effective. Perfect for weddings, photoshoots, or just a confidence boost. Highly recommend—just be gentle if you have sensitive teeth!

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
