The experts consulted for this story do not necessarily endorse the products ahead unless otherwise noted.Finding the right whitening toothpaste for you can be difficult, particularly if you have sensitive teeth. While there are plenty of options on the market, HuffPost readers have recently flocked to Mouthology’s 10% nano hydroxyapatite toothpaste, which became one of the most popular Amazon products we covered last month. We were curious to find out if the hype is real — so we asked a dentist.“The 10% nano-hydroxyapatite is the main ingredient that stands out for enamel care,” Dr. Michael J. Wei, a dentist specializing in general, cosmetic and restorative dentistry at Manhattan Cosmetic Dentist, told HuffPost when we asked him to take a look at the Mouthology toothpaste’s formula. He added, “It’s also fluoride- and SLS-free, so it may appeal to people who prefer a simpler formula.” (Many reviewers have noted that this toothpaste doesn’t foam up like many other formulas that contain SLS, which is a foaming agent.)Dentists have named fluoride as the most important ingredient to look for in a toothpaste in previous HuffPost coverage, but other dentists have also recommended nano hydroxyapatite, a calcium-based compound lauded for its remineralizing effects, to HuffPost for people with sensitive teeth in particular. So while you should be skeptical of recent fearmongering about fluoride, as it’s still widely recommended and considered safe, nano hydroxyapatite could still be right for you.According to Wei, either ingredient can be part of a healthy oral care routine. “Fluoride helps strengthen enamel by supporting the formation of fluorapatite, which is more resistant to acid,” he said. “Nano hydroxyapatite works a little differently by supplying a mineral that is very similar to the mineral naturally found in your teeth. Both can play a role in maintaining strong, healthy enamel.”AmazonThe Mouthology toothpaste contains 10% nano hydroxyapatite, as well as xylitol.In the case of the Mouthology toothpaste, that’s a 10% concentration of nano hydroxyapatite, which the brand claims is the optimal amount, citing scientific research. “There is research behind using 10% nano hydroxyapatite, but I wouldn’t say that 10% is necessarily the ideal concentration for everyone,” Wei said. “The overall formulation and a person’s individual dental needs matter too.” As with any oral hygiene product, you should consult with your dentist first.Another important ingredient in the Mouthology toothpaste is xylitol, which experts have previously told HuffPost can lower your cavity risk. “Xylitol is a naturally occurring sugar alcohol found in certain plants and fruits,” Wei explained. “It can help reduce cavity-causing bacteria and increase saliva production, which helps protect the teeth and keep the mouth hydrated.” While our previous coverage focused on chewing xylitol gum, incorporating it into a toothpaste can make your oral care routine one step easier.The toothpaste comes in a wide range of fruit, mint and cinnamon flavors, as well as an unflavored version and a version for folks with extra sensitive teeth. It’s also made in the United States. Reviewers call the toothpaste a “miracle in a bottle,” with one writing, “Now I have been using it for 3 weeks and it is great. My teeth no longer hurt, they feel so much stronger, I can drink cold and hot drinks again, and no sores in my mouth like I was getting with Crest.” Another noticed their teeth looking “noticeably cleaner [and] whiter” after just about a week of consistent use.You can find more promising reviews for this strengthening, sensitive teeth-friendly whitening toothpaste below. “I was struggling with teeth sensitivity…like drinking cold or hot drinks and I’m someone who has used all the popular “sensitive teeth” (sensodyne, Colgate, etc) mainstream toothpastes and it never got better. I ran out of options and saw this on TikTok. One tube of this stuff has changed my life. I’ll keep using it. 10/10 recommendation.” — Nicole “I wasn’t expecting to get emotionally attached to a mouth-cleaning product, but here we are. It actually tastes good, leaves my mouth feeling fresh, and makes my teeth feel noticeably cleaner. No weird aftertaste, no feeling like I just rinsed with floor cleaner, and no immediate need to drink something afterward. My mouth feels so clean after using it that I briefly consider becoming a person who flosses every day. Briefly. Definitely a winner!” — Marindap “This stuff has saved my teeth. I had a lot of chipping and weakness of my teeth during pregnancy and nursing with my kids and now menopause. I am on my second tube and my teeth have never felt better and stronger. I rave about this toothpaste to everyone.” — Amazon Customer “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 “l’ve been using this toothpaste for about a week now. My teeth definitely feel much cleaner than with any other product l’ve used. l also see some definite whitening. My teeth were quite yellow, probably due to the black coffee l drink. But l’m noticing that is improving- more so than with any of the whitening toothpastes l’ve tried. So I’m thinking l will be reordering this and see how much of a change l observe over time. So far though, l am impressed. The tube is not very big, so l doubt it will last a month, but if it continues to impress, l will gladly stick with the product.” — Cynthia Dumarin For more whitening toothpastes with glowing reviews, take a look at the list below, curated by the HuffPost Shopping team:AmazonTheraBreath's whitening toothpaste that's worth its weight in goldIf 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 hoosierAmazonA two-step cleaning and whitening kit from a dependable brandThis Crest two-step cleaning kit includes one tube of deep cleansing toothpaste (step one) and a tube of whitening gel (step two), and reviewers swear it works wonders. “My teeth are sparkling and my confidence is through the roof,” one happy user says. “After just one use, I’m pretty sure I could blind a small army with how white my teeth are now.” This two-step whitening system works in tandem to give you a brighter smile. For the first step, you brush with the 4-ounce deep-clean toothpaste tube for about a minute, then spit. Instead of rinsing your mouth with water after step one, you instead start brushing with the 2.3-ounce whitening gel for step two. Then, spit and rinse like normal. It’s fuss-free compared to having to take out Crest whitening strips, carefully place them on your teeth and wait up to 30 minutes for it to do its magic.Promising review: "Best whitening system I have ever tried. You know how too often you buy the must-have new thing that's "too good to be true"? This ain't one of those times. This stuff is AMAZING. In just 3 applications my teeth are shades whiter. And they don't hurt or anything. So glad I tried it. Seriously."AmazonA vintage-inspired whitening toothpaste that reviewers adoreEuthymol's whitening toothpaste is gaining traction as one of the brand’s most iconic products, packaged in a sleek, fully recyclable aluminum tube with a retro-inspired design that reflects the brand’s more than 125-year history. The formula works as an everyday toothpaste while targeting stains from several fronts.It contains fluoride to strengthen enamel and help protect against cavities, and sodium hexametaphosphate, which can help to prevent stain-causing particles from sticking to the enamel. The formula also includes hydrated silica, a polishing ingredient that helps lift plaque and surface discoloration as you brush. Together, these ingredients brighten teeth while delivering the ultra-fresh, just-cleaned feeling longtime fans rave about. One reviewer even described the effect as “oven cleaning for your mouth.”Promising review: "this toothpaste is the real deal! I first saw it overseas on a trip to japan and purchased it and now i get it here. it gently whitens and freshens breath. it is now my every day toothpaste and i don't leave home without it!! love the taste, its pleasant and its pink, how cute :) does not radically affect sensitivity like other whitening toothpastes, but is very gentle. Despite being gentle it is still super effective. i see the difference in the color of my teeth in less than a month. I can see it in pictures even when i wear a white shirt. great quantity as you don't need to use much on your brush." — BjP
