I had never used Whitestrips of any kind before and I was a little hesitant to try them, but after reading a ton of reviews I decided to give these a try. This type, the Professional Effects Plus, contains 48 strips. This is a commitment. You need to use them every single day for 20 days. The last 4 strips are for "emergency" use for special occasions. I had some sensitivity with these strips that usually dissipated after a day or two. The results were good. I would say at least 4 shades lighter than what I started with. These will not have any effect on false teeth, bridges or crowns. If you can commit to using these strips as recommended by the manufacturer, you should get good results. Tip: it is better to dry your teeth with a cloth before applying the strips. They will stick better.

I don't have any before and after pics but, they work great! Did one application tonight and can already see the difference. As far as sensitivity, I don't feel anything on my gums at all, but I just did one app, after that I wait little bit and brush with sensodyne tooth paste only! Don't need to use Crest whitening past until you are done with how white you want your teeth. I would buy again!

They do work as they should, I never though I would get brighter teeth since I have been drinking coca cola for more than 10 years and my teeth were really stained, but they did help me a lot, almost white teeth! I will buy 2 more for this year since you can only use them every 6 months due to sensitivity on your gums/teeth.

These work great but no matter what Crest says, these are still a hassle to get them to stay in place and not slip around on your teeth! The marketing and descriptions are always going to lie to the consumer saying “non-slip” or something to that effect but the FACT remains, these slip and slide and crinkle up while on your teeth. They also are sometimes hard to get off the sheet that they are adhered to and when they wrinkle or bend to the point that you can’t get them to adhere to your teeth uniformly then you basically get screwed out of a product that you cannot apply as directed! Crest knows this and these have always been a pain to use as noted above. If you get them on right to where you get lucky, then they are awesome in the fact that they do whiten your teeth significantly! Getting it on sale is a great deal and to me it is the only time to purchase these.

I was skeptical at first, but after using the Crest 3D Whitestrips Professional Effects Plus, I noticed a visible difference in just a few days. The strips are easy to apply and stay in place well. By the end of the treatment, my teeth looked significantly whiter, almost like a professional whitening. No major sensitivity issues for me, but if you have sensitive teeth, you might want to use them every other day. Definitely worth the investment for a brighter smile!

I love this product and was able to see results in about a week. I did get random sharp pains on my front teeth when I had them on but it was nothing too crazy. Definitely recommend, but if you're sensitive I might look for something else.

Way better than the old ones that had a strip of glue, easy to use, and decent whitening. Still not the same as the professional whitening but it does the job if used daily for 45 min over 7-10 days

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.

As advertised, works very good.

Perfect for what I needed. As described

It does make my teeth whither

المنتج وصلني تالف تماما العلبه متقطعه وحتى اللصقات من داخل معدومه تماماً واضح انه معاد استخدامها وتاريخ انتهاء صلاحيته 2024 واحنا 2024 اساساً!!! والمنتج مو مسجل بهيئة الغذاء والدواء حطيت الباركود بطمني طلع مو موجود وسويت بلاغ ما انصحكم تاخذونه👌🏻

I love these whitening strips. They really do work. I just wish they were more accessible in Australia so they would become cheaper. I haven’t found anything that whitens teeth as well as these strips however they can cause some sensitivity but I just brush with sensodyne toothpaste when using the strips and that helps a lot.
