I haven’t been able to use these in the past because they made my teeth and gums sensitive after 2-3 applications. I saw a hack where you use synsodyne toothpaste for the time you are utilizing these strips. Also-cut the strips in half so they only cover the front side of your teeth. I’ve been doing both of these things and I’m on day 9, absolutely no sensitivity at all and the results are great. I wish I had known about this sooner! Read more

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. Read more
