Try these teeth-whitening strips for yourself while they’re on sale, and take a look below to see how reviewers are raving about this bestselling Crest product.
“I was fortunate to receive this Crest 3D Whitestrips kit, and overall I’m very pleased with the results. While the packaging suggests you’ll see dramatic whitening in just a few days, that felt a bit exaggerated. In reality, it took about two weeks of consistent use before I noticed a clear improvement in the brightness of my teeth.
The strips are easy to apply and stay in place well during the 60-minute treatment. I did experience some mild tooth sensitivity during the first few days, but it was manageable and didn’t last long. After completing the treatment, my teeth look noticeably whiter and I feel more confident smiling.
This product offers a convenient and effective at-home whitening option, especially if you’re willing to be patient and follow the instructions consistently.” — Tyler Graden
“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.” — armando
“I’ve been using Crest 3D Whitestrips Professional Effects Plus for about 20 days now, and the results are seriously impressive. These strips use a hydrogen peroxide formula—the same enamel-safe whitening agent dentists use—to lift years of surface stains from coffee, wine, and even tomato sauce.
One of the best features is the Advanced Seal Technology, which really works—the strips stay put allowing you to eat, drink water, or chat while wearing them.
I noticed a subtle brightening around day 3 or 4, and by the end of the full course, my smile was noticeably several shades whiter.” — gnomze
Looking for more ways to upgrade your oral health? Check out some of these mouthwashes dentists actually recommend using, courtesy of senior Shopping writer Tessa Flores.
A remineralization oral rinse
"My practice uses the CariFree mouthwashes as they balance pH, help dry mouth and aid in balancing bacterial load/aiding in gingivitis prevention," said Dr. Inna Chern of Manhattan's New York General Dentistry,
This anti-cavity oral rinse contains fluoride and xylitol, both essentials in fighting bacteria, and has an elevated pH to neutralize decay-causing acids in the mouth.
An often sold out whitening fluoride rinse
"I encourage patients to use mouthwash containing fluoride when they are at risk of [cavities] or have dental sensitivity," said New York City-based dentist Dr. Azadeh Akhavan, recommending ACT Whitening as a good mouthwash to use for its fluoride-containing formula.
In addition to fluoride, this particular anti-cavity preparation helps to whiten teeth with the use of hydrogen peroxide, an effective stain-lifting agent that Akhavan said should be avoided only in high concentrations because it has the potential to abrade enamel. This popular zero-alcohol rinse also contains bacteria-fighting xylitol and glycerin.
An oral rinse for dry mouth
"For individuals undergoing radiation therapy or taking medications that cause dry mouth, regular use of a mouthwash containing a wetting agent is important for keeping the mouth moist," Akhavan said. Bacteria binds more readily to teeth in a dry mouth, resulting in bacterial colonies that promote cavities or problems with the gums and supporting bone.
In cases like these, Akhavan suggests Biotene oral rinse because it contains glycerol, a mouth moisturizer that quickly soothes and lubricates the mouth for up to four hours. The brand also claims this formula works to help maintain a balanced pH in the mouth.
"Biotene or any mouth-wetting mouthwash should also stay on the teeth as long as possible, without dilution, for maximal effectiveness. So ideally, mouthwash should be used prior to bedtime with no rinsing after use," she added.
A pH-balancing mouthwash with xylitol
Akhavan also said baking soda and xylitol are two great mouthwash ingredients.
"Baking soda decreases the pH of saliva and discourages bacterial growth and xylitol prevents the binding of bacteria to the teeth," she explained.
One brand she liked is no longer in production, but we spotted this pH-balancing mouthwash by Cleure that features baking soda and xylitol and is free from Akhavan's less-favored ingredients like alcohol and acidic fruit flavorings that can erode enamel over time. This simple-ingredient mouthwash also contains glycerin, a popular hydrator that can help address dry mouth.
An alcohol-free wash good for gingivitis
According to Chern, mouthwashes that contain certain essential oils including thymol, eucalyptol, menthol and methyl salicylates are great for anyone who has or is prone to gingivitis.
This Total Care option from Listerine contains all four of those oils in addition to fluoride in order to protect against cavities — all without the inclusion of alcohol, which Chern said can cause or exacerbate dry mouth.
"If you have a high risk of cavities, mouthwashes with extra fluoride or nano-hydroxyapatite are excellent in preventing future cavities," Chern said.
A nano hydroxyapatite oil pulling rinse
"If you have a high risk of cavities, mouthwashes with extra fluoride or nano-hydroxyapatite are excellent in preventing future cavities," Chern said. Although she didn't recommend one wash in particular, we found this oral pulling rinse containing nano-hydroxyapatite that, unlike most oil pulling products, promises that it won’t clog your bathroom sink drains. Oil pulling, the practice of swishing oil around your mouth each day, is an ancient Ayurvedic practice that has some research to support it can help keep the mouth clean, freshen breath and and improve overall oral health.
Mouthwash tablets with hydroxyapatite and probiotics
"One thing that will be interesting to watch is hydroxyapatite, an ingredient that some toothpastes are starting to include," Akhavan said. "Very preliminary studies suggest that it may be as effective as fluoride toothpaste in strengthening the enamel."
Based on this mention, we tracked down Boka's convenient mouthwash tablets that contain hydroxyapatite instead of fluoride to help remineralize teeth without stripping the mouth of important microbes. The Boka tablets, which don't require water to use, also contain dentist-preferred ingredients like baking soda and xylitol.
