If you want to give your teeth a little color boost, you may be ready to drop some dough on a dentist’s office treatment or home strips from a big-name brand. Before you do, we recommend peeking at this highly rated, lesser-known whitening kit from vegan dental brand Twice. Not only do reviewers call the Twice strips more effective than other kits they’ve tried, but they straight-up deem the them “better than $150 whitening from the dentist.” Regularly $25, a set of 40 strips (20 treatments), is currently a whopping 40% off on Amazon, dropping it to $15 — the lowest price it’s been, ever.
Reviewers, especially those with sensitive teeth, love the set for working fast, having “no weird chemical taste” and not leaving teeth irritated after use.
Made with hydrogen peroxide, coconut oil, glycerin and menthol, the strips are intended to cool and soothe your mouth as they whiten. Fans say they started seeing the whitening start as early as three days into using the strips, transforming “some very yellow teeth,” into “decent shade of almost white,” in just five days, with no pain or irritation.
“The best thing about these strips is that they do not cause teeth sensitivity,” Sandy wrote. ” Other strips I would have to use every other day to give my teeth a chance to calm down. I could use these every day with no effect on my teeth.”
Another reviewer, LFRogala says the Twice strips’ whitening power is “about the same” as harsher whitening products, while miraculously being far gentler to the teeth. ”...My teeth have been less sensitive after using,” they wrote. “With other brands, my teeth have been sensitive for a few days afterward.”
Users appreciate the strips’ generous size (as one says, “large enough to cover all visible teeth”) and superior sticking power, which keeps them in place, even when you’re moving around. “Most other strips I have tried don’t stick well and come off before they are supposed to,” one wrote.
Another reviewer calls the strips “by far the easiest and most effective ones that I have tried,” with “maximum adhesion,” which is still mess-free and easy to brush off, after the 30-minute treatment time is done.
Reviewers are clearly smiling brightly for this on-sale, gentle whitening kit from Twice. Read more 5-star reviews and grab a set while it’s 40% off.
“2nd time I bought. Yes they work better than anything else I tried. Better than $150 whitening from the Dentist. And it doesn’t make your teeth hurt” — fj695
“I’ve been using the Twice Teeth Whitening Strips for over a week now, and I have to say that they are by far the easiest and most effective ones that I have tried. I do recommend drying your teeth before applying to maintain maximum adhesion. They are super easy to apply and, so far, I have not experienced any gum sensitivity or irritation, and they have stayed in place without slipping. An added bonus is the mild mint flavor makes me forget about the 30-minute treatment time. I apply them while watching TV before going to bed. Once they are removed, remember to brush your teeth and gums thoroughly to remove any residue.
Overall, they are comfortable to wear, easy to use with no mess, large enough to cover all visible teeth, and have a strong adhesive. I drink a lot of coffee and tea throughout the day. After seven days of use, all those stains are gone and my teeth are visibly whiter. At the current price of $24.99 for 20 treatments, I think they are a great value for the money.” — B. Judy“The best thing about these strips is that they do not cause teeth sensitivity. Other strips I would have to use every other day to give my teeth a chance to calm down. I could use these every day with no effect on my teeth. They say they are mint but I barely tasted anything. I used them before bed and brushed my teeth right after. It took about three days before I saw any effect, and five days to get to a decent shade of almost white. Granted I started with some very yellow teeth. After three days I started cutting them in half because they were hard to get off my teeth when I wrapped them around - like glued on hard to get off. The box says to use them for about 5-7 days so I’ll stop and do it again in a couple months. The expiration date says they will last a year. The distributor is in the USA, the strips are made in China.” — Sandy

Promising review: "So easy to use and works great! And… less expensive than Crest white strips!" — songlove2
A 3-pack of Colgate Optic White whitening mouthwash (25% off)
Like whitening toothpaste, whitening mouthwash like Colgate Optic White can be an easy way to maintain a whiter smile without doing treatments that are more involved. Now, the brand says the mouthwash works to eliminate surface stains and prevent new ones, so it's not going to be as in-depth as a professional-level treatment. Still, it freshens breath, kills bacteria, is alcohol-free and is a great step for maintaining your pearly whites. Get a 3-pack for 25% off to give the whole family something to smile about.
Promising review: "This stuff has pulled me back from the brink of despair, no joke! White teeth have always been a cornerstone of my sense of personal attractiveness, but over the past two months something must have changed in my life or my mouth chemistry, because my teeth became very yellow and even grayish in places! (Gasp) The really scary thing was, they were responding only minimally to the Crest white strips I’ve sworn by for decades. I felt mortified and helpless, and I concluded I’d just have to save big money to have them treated at the dentist. I got this mouthwash on a whim, and started using it as part of my obsessively thorough oral hygiene routine, with zero expectations of any kind. Imagine my astonishment when about a week later, I was looking at a much more familiar set of teeth in the mirror. I’m positive that my renewed brushing fervor had a lot to do with it too, (though bear in mind I’m allergic to everything, so my toothpaste has nothing useful in it), but I believe this product does actually work. I’m not even swishing with it twice a day. I AM using it for a full minute instead of 30 seconds though (but not longer, bc I don’t want to damage my enamel) (Speaking of enamel, I follow this with @ fluoride mouthwash and don’t rinse with water afterwards - this can actually remineralize your enamel and keep those teeth forming becoming discolored!)
Oh, one more thing I love about this whitening rinse... it treats the whole mouth evenly! I used to cut up white strips and use extra on the sides sometimes because the product doesn’t wrap around all your teeth, so I’d get kind of an unfortunate ombré going on the left and right. I’m seeing much less of that with this rinse! Pretty sure I’ll be a customer for life!" — Missy
A purple color-correcting serum (20% off)
Last year, we covered the Hismile V34 tooth whitening color correcting serum, the purpleness of which may surprise you. The reason it's purple is to neutralize your teeth's yellow undertones, making them appear whiter. This is a temporary effect, as it's only occurring on the surface, and dentists say you shouldn't overuse it (it isn't toothpaste). Still, if you want a cheap way to get a whitening effect that's gentle and peroxide-free, this is a much more affordable alternative to Whitestrips. Hot tip: until March, 14, Target Circle Members (Target's free rewards program) can get 20% off this, or a bunch of great dental care and body items, when you hit the coupon before checkout.
The Real Deal: We use deal trackers and commerce experience to sift through “fake” hike-and-drop deals and other deceptive sales tactics. Products will usually be rated at least 4 stars with a minimum 15% discount. (And when there’s an exception, we’ll tell you why.)
