Natural toothpaste brands are becoming more eco-friendly, offering pastes, powders, and even tablets, to help you get that gorgeous, healthy smile. But are they as good at protecting your teeth from cavities?
“The oral-care aisle can often feel like a homework assignment, especially when it comes to decoding the natural options. Tubes feature botanical illustrations, promises of instant whitening, and even claims that fluoride-free formulas are better for you and the planet—confusing, if not completely exhausting. But when oral health needs go beyond brightening, like cavity prevention or gum disease treatment, the question becomes more complex: does a natural toothpaste have to forego fluoride? And, critically, should it?”
Fluoride is not a synthetic contaminant but a naturally occurring mineral found in soil, water and certain foods. When used at recommended levels, it strengthens tooth enamel and helps reverse early decay. The American Dental Association points out that fluoride toothpaste reduces the risk of cavities by 25 percent in both children and adults, and the Centers for Disease Control and Prevention note that community water fluoridation lowers cavity rates by roughly 25 percent. Fluoride works before teeth erupt and after, remineralizing enamel; it is safe when used properly, which makes the fear around it more myth than reality.
Still, many consumers are drawn to fluoride‑free toothpastes because of their natural ingredients. These products often rely on xylitol, a plant‑based sweetener that disrupts energy production in cavity‑causing bacteria. Hydroxyapatite, the mineral that forms the bulk of tooth enamel, is another popular addition. Yet the evidence supporting these alternatives is limited. Research shows that xylitol toothpaste does not outperform fluoride, and hydroxyapatite and nanohydroxyapatite have not been approved by the U.S. Food and Drug Administration. Fluoride, on the other hand, has been regarded as “one of the great public health achievements” for its ability to prevent demineralization, help minerals return to enamel and inhibit bacteria.
Environmental concerns also influence toothpaste purchasing decisions. Many natural toothpaste brands emphasise eco‑friendly credentials, yet the biggest environmental impact often comes from packaging rather than ingredients. Most conventional toothpaste tubes are made from layers of plastic and aluminium, making them difficult to recycle. Globally, around 1.5 billion tubes are thrown away each year; in the United Kingdom alone, 300 million go to landfill, and each tube can take centuries to break down. These tubes are hard to recycle.
Microplastics are another issue. The U.S. Microbead‑Free Waters Act banned plastic microbeads in rinse‑off personal care items such as toothpaste, and the European Union enacted similar restrictions with a transition period through 2027. These particles escape wastewater treatment and accumulate in rivers and oceans. Choosing a fluoride‑free formula does not address these environmental challenges; look instead for recyclable tubes, refillable containers or toothpaste tablets and powders.
Making an informed choice involves separating marketing from science. Fluoride is a naturally occurring mineral with decades of evidence behind it. Alternatives like xylitol and hydroxyapatite may support enamel but should not replace fluoride, especially for children. To reduce your environmental footprint, prioritise recyclable or reusable packaging and avoid abrasive ingredients like charcoal or pure baking soda, which can erode enamel. Choosing toothpaste becomes easier when you look beyond slogans: natural isn’t always more eco‑friendly, and fluoride isn’t an industrial toxin but a mineral that protects your teeth.
What about the toothbrush?
Your dentist will tell you your toothbrush choice matters — a lot. While the disposable kind work in a pinch or when you’re traveling (there are eco-bamboo and recycled plastic options for those occasions), experts recommend going electric. Not only do electric toothbrushes do much of the work for you, but they do it better. Dentists love the Oral-B electric brushes, or try Moon for a chic ergonomic design and a range of settings. But it’s hard to go wrong with any of them.
On the note of electrifying your brushing, you can electrify your flossing, too, with a Waterpik. It can be more effective than conventional flossing, which many dentists will tell you is more important than brushing anyway.
Eco-friendly natural toothpaste brands
What makes a toothpaste brand eco-friendly? There’s no one catch-all definition, but a few things make a difference — from ingredients to packaging. The same goes for natural: the cleaner the ingredients, the more natural it is, even though there’s no formal definition for “natural.” Zero-waste toothpaste brands like the few tablets on this list are a great place to start your journey to sustainable toothpaste. Give these brands a try.
Bite
Bite promises to keep your pearly whites pristine with its vegan, cruelty-free and eco-friendly toothpaste bits. Packaged in a recyclable glass jar, these ‘bits’ are simply natural toothpaste tabs and they’re super easy to use. Just pop one in your mouth, bite down, and brush (also make sure to wet your toothbrush to get the best results).
One jar contains enough toothpaste bits to keep you going for 4 months. At $30 a jar, that’s about 25 cents per day. Plus, after your supply is used up Bite will deliver a refill in compostable packaging through the easy subscription service.
Not sure it’s a fit? Try them out on a trial basis at just $12, with the smaller bottle containing enough bits to last you for around a month.
Why we love it: The convenience can’t be beat and the natural ingredients deliver fresh breath and keep teeth naturally white without harsh chemicals.
Tom’s of Maine
Tom’s Whole Care Fluoridated Toothpaste offers a straightforward way to protect your smile with a formula that’s both effective and responsibly made. Crafted with fluoride to help prevent cavities and strengthen enamel, it also contains natural ingredients like zinc citrate for tartar control and xylitol for a burst of freshness. The toothpaste is free from artificial flavors, colors, or preservatives.
A standard tube lasts for months with twice-daily brushing, making it an affordable choice for maintaining oral health.
Why we love it: It delivers the cavity-fighting benefits of fluoride with naturally derived ingredients, all in eco-conscious packaging you can feel good about using every day.
Huppy
Like Bite, Huppy has also jumped on the toothpaste tablet train. Its tabs are completely plastic-free, non-GMO, cruelty-free and, it should be noted, extra minty. On top of that, they’re also super simple to use. Just pop one in your mouth, chew, and brush twice a day.
You can either buy a four-month’s supply or try these eco-friendly toothpaste tabs on a trial basis. When you purchase, you’ll also be provided with a plastic-free Huppy container, and every refill is packaged using compostable materials.
In case you needed any more convincing, Huppy has also been given the seal of approval from Women’s Health and the Self Healthy Beauty Awards.
Why we love it: Another super easy travel option with exceptional flavor and nice foaming action. Not for the peppermint averse!
Georganics
Whatever kind of dental product you’re looking for, Georganics have got it. From toothpaste tabs and pastes to plastic-free floss and mouthwash, as well as mineral toothpaste powder. You’ll find them in a range of flavors ranging from your standard peppermint to charcoal.
All are cruelty-free and vegan, flavored with organic oils that naturally remove stains and whiten teeth. To use, simply dip your toothbrush into the recyclable glass jar to coat with powder, and then brush as normal.
Why we love it: The powder or the tablets offer you an easy way to brush. The spearmint flavor isn’t overpowering, either.
Davids
Founded in 2011, Davids is an old hand when it comes to producing top-quality eco-friendly dental products. One of the few pre-formulated kinds of toothpaste on the sustainable market, all of Davids products come in recyclable metal tubes which are not only better for the planet, but much easier to squeeze than classic plastic tubes.
The brand’s vegan toothpastes are fluoride and SLS-free, and 98 percent of ingredients are sourced in the U.S., where the company is based, thus saving on further carbon emissions.
Why we love it: Davids gives classic toothpaste a modern makeover with a fully recyclable metal tube and old-fashioned minty paste inside. So good you’ll never forget to brush!

It uses plant-based, natural ingredients such as aloe vera, bamboo, coconut oil, palm oil, stevia, and mint, and never tests on animals.
“Brushing. Rinsing. Smiling. It’s all good. But you know what’s not so good? Testing products on animals or adding in animal-derived ingredients where they aren’t needed,” the company says on its website. “We’re all part of this planet, so it’s important that consumer products—including oral care ones—are good to our bodies, our furry friends, and the environment.”
Why we love it: Charcoal toothpaste brightens your smile but some can taste a bit like … charcoal. Hello delivers the benefits in a natural, vegan minty paste that tastes great.
