Best Natural Toothpaste
Most conventional toothpastes have fluoride, SLS, and artificial flavorings or colorings. Natural toothpastes tend to avoid those harmful chemicals and so many more, opting for all-natural ingredientsthat are safer to put in your mouth.
This article contains the top 4 best natural toothpastes for dental health, according to Dr. Gerry Curatola, a leading biologic dentist with decades of experience helping people like you take control of their oral and systemic health.
1. Revitin
Cost: $17 for 3.4 oz. tube, discounted when you buy multiple tubes
Revitin is the gold standard for all-natural toothpastes. This natural whitening toothpaste supports your oral microbiome while offering fresh breath, clean teeth, and a pleasant mouth feeling.
Developed by a leading biologic dentist, this plant-based toothpaste empowers your oral microbiome’s natural ability to fight plaque and remineralize teeth, instead of what other “natural” toothpastes do — kill good bacteria along with the bad, and fill your mouth (and body) with nanoparticles.
The evidence behind Revitin’s effectiveness is three-fold:
Microbes are necessary for your oral health.That’s why Revitin is prebiotic, empowering beneficial bacteria to thrive in your mouth while reducing harmful bacteria like salivary Streptococcus mutans.
Harsh chemicals do more harm than good. So many toothpastes (even natural ones) contain abrasives and antibacterials that harm your microbiome and dental enamel. Revitin is safe, avoiding harsh chemical ingredients.
Natural ingredients work very hard.Revitin uses all-natural ingredients that strengthen your oral microbiome, whiten teeth, enhance antioxidant activity, and even support gum tissue repair.
We don't recommend this, but Revitin is safe to swallow, making it an excellent choice for all ages.
This is our choice for a “do-no-harm” type of toothpaste. It doesn't have xylitol or other bad stuff found in many natural toothpastes. It’s been a pretty clean, cruelty-free brand; they’re certified “natural” by NATRUE. It should freshen breath and help prevent gingivitis.
Their eco-friendly salt toothpaste is their best seller, but they also have three other types of toothpaste: Plant Gel, Ratanhia, and Calendula. These are pretty good fluoride-free options, but alcohol as an ingredient knocks it down a peg — alcohol often leads to xerostomia (dry mouth).
This is an Ayurvedic herbal mint toothpaste. Some of the oils they use (in the toothpaste) are antimicrobial, which may not be beneficial to your oral microbiome. Auromere uses cruelty-free botanical extracts, so we definitely consider them natural.
Adhering to the traditional Hindu system of medicine (Ayurvedic), this oral health company offers other natural oral care products, including alcohol-free mouthwash, a plastic-free tongue scraper, and birchwood toothpicks infused with healthful botanical extracts.
This is a drugstore brand of toothpaste. It’s an okay natural toothpaste that doesn’t have xylitol or erythritol, but it can be harsh on the microbiome.
However, Dr. Bronner’s toothpaste doesn’t contain fluoride, SLS, carrageenan, triclosan, parabens, or other harmful ingredients that can significantly impact your oral microbiome and systemic health.
The benefits of using natural toothpaste over conventional ones concern the effect of certain toxic ingredients on systemic health. Due to these microbiome and systemic benefits, the 4 toothpastes mentioned above should be a net positive for oral health and overall wellness.
Natural toothpaste benefits:
Better for your oral microbiome.
Gentler on tooth sensitivity than conventional teeth whitening toothpastes.
Replaces harmful man-made chemicals with natural ingredients.
Reduces your risk of dental fluorosis or skeletal fluorosis.
Usually doesn’t have fluoride, which may have adverse effects on your brain, liver, kidneys, and so much more.
Doesn’t contain SLS (sodium lauryl sulfate), which is linked to decreased “oral wound healing” and increased “irritation of the oral mucosa.”
Doesn’t have unidentified preservatives, artificial sweeteners, colors, and flavors that may contribute to inflammation and other health problems.
Better and safer than conventional toothpastes, but also better than no toothpaste.
While some folks may think, “natural is just better,” not all “natural toothpaste” is great for your oral health. Aim for quality ingredients and avoid toxic ingredients — even ones accepted by conventional “experts.”
Avoid These “Natural” Ingredients
Recent research has revealed that certain all-natural toothpaste ingredients are actually not that good for your health. Below are the “natural” toothpaste ingredients you should avoid:
Hydroxyapatite: Maybe it’s good at preventing tooth decay and remineralizing cavities, but hydroxyapatite nanoparticles from natural toothpastes can be found in the lungs, kidneys, and more organs, increasing your risk of systemic health problems. We cannot recommend popular hydroxyapatite toothpaste brands like David’s and Boka.
Erythritol: This natural sugar alcohol seems to mess with your body’s coagulation. An NIH-funded study found that erythritol was associated with increased risk of heart disease, blood clotting, and stroke.
Xylitol: Though seemingly not as dangerous as erythritol, xylitol showed similar blood clotting issues as erythritol. Until we get better long-term studies on xylitol’s effect on your heart health, we should not be consuming xylitolon a regular basis.
Activated charcoal: Although charcoal may effectively remove surface stains, it doesn’t really have any health benefits that a napkin doesn’t also have. It’s also incredibly abrasive, eroding dental enamel and wreaking havoc on sensitive teeth.
Brush Your Way to a Better Smile
A good oral care routine is essential to oral health and a balanced microbiome. Brush twice daily with a sonic, soft-bristled toothbrush and a natural prebiotic toothpaste, floss daily, mouth rinse with water after meals, or try coconut oil pulling. Don’t forget to visit your dentist twice a year.
Dental healthcare professionals not only clean your teeth better than you can at home, but they can also catch oral health issues before you might notice symptoms — nipping mouth diseases in the bud without requiring severe measures.
