After Using This $50 Kit, ‘Even My Dentist Said I Could Not Have Gotten A Whiter Smile With Their Products’
If you're looking for a literal smile glow-up, grabbing Crest's 3D Whitestrips kit with a handheld LED light is one seriously bright idea — especially when it's on sale for up to 29% off. That's saving some serious dollars on an at-home treatment that reviewers say rivals professional whitening. "My dentist even remarked about how white my teeth were and asked where I went to have them done," one wrote about the two-step kit. "She couldn't believe they were [whitening] strips by Crest."
You get all the pearly whiteness of traditional Whitestrips, plus a handheld light to help break down stains even more efficiently.
The kit comes with 10 or 20 teeth whitening treatments (depending on whether you get the 20- or 40-pack), each with one upper and one lower whitening strip, to ensure every tooth gets treated. Yet, the star of the show is the handy LED whitening light, designed to help break up staining and discoloration on your teeth. Simply pop both strips on your teeth for 60 minutes, then use the LED blue light for five minutes over the strips. After using the light, dispose of the strips, rinse your mouth and go about your day!
The brand says the light helps the peroxide in the whitening strips work both faster and stronger — something confirmed by reviewers. "I've used the strips for years, but with the light therapy you're getting a whole new white," shopper Rhonda wrote. "It doesn't take long either."
With another writing that after just two weeks of using the strips and the light, their teeth look "30 times" whiter. "I truly thought it was impossible to ever get my teeth white," they said. "...They are not just white they are brighter and [have] an unbelievable beautiful glowing white color... this stuff is amazing..."
Reviewers say the kit helped brighten their smiles and upped their confidence — fast. Apparently, the LED light with the strips is one winning combo.
So many reviewers say this combination of Crest Whitestrips and the LED light quickly removed years-old stains that they thought they'd have forever. "Within just a few uses, I noticed a significant improvement in the whiteness of my teeth," shopper Danny wrote. "Stubborn stains from coffee, tea, and other food stains were visibly reduced, and my teeth appeared several shades brighter."
Another shopper who was quoted $500 for a professional whitening says this at-home kit " transformed " their life — after only four days. "After the first day it removed so much of my yellow stains," they said. "I can't even think about how white my teeth will be when I finish."
Others call the kid a "must-have for anyone seeking a dazzling and confident smile ," saying it's helping them show off their teeth more freely and feel "less embarrassed " when taking photos. "The biggest difference for me is not just the color, but how much more confident I feel when I smile now," Ivo wrote. "That alone made it worth it."

TheraBreath's whitening toothpaste that's worth its weight in gold
If you haven't heard about TheraBreath's widely beloved toothpastes, just know the line may put your dentist out of work (we're only sort of kidding). That line includes a whitening toothpaste , sold in a two-pack, which is peroxide-free and works to eliminate bad breath and whiten your teeth at the same time. According to the brand, you can see significant results in as little as one week with twice-daily brushing. The toothpaste is minty fresh and made in the USA. While we admit it's far pricier than a lot of toothpaste out there, this is one that seems to be more than worth the extra cost (and can potentially help you save on expensive whitening treatments, as one reviewer pointed out ).
Promising reviews: "I'm not one to leave reviews I honestly thought this was a scam, but after a week of use I can definitely tell that my teeth are getting whiter. This product is awesome and if you paired it with the oral rinse even better." — Frank
"I'm always skeptical when I buy a new whitening toothpaste, I usually bleach my teeth, but I have gotten lazy. I have tried several different brands, and this so far has the best potential, I've only been using it a week and my teeth are visibly whiter.Give it another try." — megan hoosier

A restorative toothpaste that whitens and helps with sensitivity
Made with a generous 10% nano-hydroxyapatite , a government-studied calcium-based compound for restoring and protecting teeth, this fluoride-free, mint toothpaste from Mouthology may be your next dental purchase. The magic comes from nano-hydroxyapatite , an engineered compound that mimics the natural material found in your teeth. The substance has been studied a ton and is often used in dentistry, specifically for its ability to restore enamel, fill in tiny holes, reduce sensitivity, ward off plaque, and generally strengthen teeth.
"After using it consistently, I've noticed a real difference in my teeth," one reviewer wrote. "They feel noticeably stronger, look whiter, and my sensitivity has gone down significantly, especially with hot and cold foods. It's rare to find one toothpaste that checks all three boxes."
Promising review: "Love the subtle minty taste, the no foam formula, the whitening properties of this toothpaste and the enamel restoration which is NOT hype. I have older dental work that was becoming noticeable. A few weeks of using this toothpaste day and night is reversing the state of my caps and crowns so that they are looking newer, fresher. Teeth are smooth and whitened. Breath is fresher, gums look healthier. No more bleeding, burning, mouth sores or gum irritation. Best thing we've done is switching to this toothpaste for our oral health. Highly recommend!"— Auntie Mel
