"My teeth have been sensitive for years. Within two weeks of switching to Fygg I noticed a dramatic difference. I can drink cold water again without flinching."
"My dentist told me I had three watch spots six months ago. After using Fygg in my retainer every night, my last checkup showed all three had remineralized."
"My dentist asked what I had changed at my last cleaning. My enamel was visibly stronger and she said my gum health had improved significantly. She now recommends Fygg to her own patients."
Why Fygg
Traditional toothpaste kills good bacteria along with the bad. Fygg feeds your oral microbiome so it can protect you naturally.
Nano-hydroxyapatite bonds directly to your teeth, filling micro-cracks and rebuilding enamel without fluoride.
Prebiotics like chicory root and xylitol feed the beneficial microbes that keep your mouth—and body—healthy.
Free from fluoride, SLS, essential oils, endocrine disruptors, and detergents. Nothing that doesn't belong.
Clinically proven n-HAp fills exposed dentin tubules, reducing sensitivity from the very first use.
The Science
The same mineral your teeth are already made of—delivered in nano-sized particles that bond directly to enamel.
Nano-sized hydroxyapatite particles are small enough to penetrate micro-cracks in your tooth surface, filling gaps that traditional toothpaste can't reach.
Once bonded, n-HAp acts as a scaffold for new mineral deposits, effectively remineralizing weakened areas and restoring the tooth's natural protective layer.
The rebuilt surface is smoother and more resistant to acid attacks from food and bacteria—reducing sensitivity and making future cavities less likely.
“Fygg is so much more than a toothpaste. It’s a daily way to support the health and diversity of your oral microbiome, the complex community of microbes that helps maintain balance, not just in the mouth, but throughout the entire body. Fygg supports one of the most accessible and important gateways to lifelong wellness.”
“Fygg is the hydroxyapatite toothpaste I use for myself and my family because of the ingredient quality, not to mention - I also enjoy the taste!”
“I often recommend Fygg to my patients as part of a comprehensive, root-cause approach to health. Its science-backed formulation supports key areas and the beautiful branding is an added bonus.”
“Our practice really loves Fygg toothpaste and varnish! Very few oral hygiene products impress me, after 40 years in practice and these products do. They are truly clinically effective. When selecting nano-Hydroxyapatite products to recommend, sourcing of ingredients MATTERS. Fygg products are one of the few containing “NanoXIM” - it is safe and effective”
“I absolutely love using and recommending Fygg as part of a whole-person plan. The oral microbiome is such a critical place to start in overall health since it's the gateway to the rest of the body. The microbiome impacts all systems of the body, including the immune system and hormone production! I love that I can trust the science-backed, clean ingredients in their oral health products.”
“As a holistic dental hygienist, my focus is always on patient health and oral wellness- it is important to me that products work without toxic ingredients. As a mom, it is equally important that what we use at home sets my kids up for a lifetime of good oral health. I recommend FYGG for my family, friends, and patients! FYGG has helped people with sensitivity and those with cavities. 10 out of 10 would recommend!”
“Fygg has been a miracle for patients with sensitive teeth and gums! Whenever I’ve had patients with temporary crowns that have come off, Fygg works incredibly well as a treatment for sensitivity! We don’t go a day in the office without using it on our patients, and I highly recommend it to all my patients!”
“As a holistic dentist, I’m constantly looking for products that align with my commitment to natural, safe, and effective oral care. Fygg has impressed me with its thoughtful formulation, dedication to quality, and support for overall oral health without the use of harsh chemicals or artificial ingredients. Fygg has set a new standard for what natural toothpaste can achieve.”
“We’ve incorporated Fygg varnish into our remineralization protocol. We avoid products with fluoride because they seal in the white spots. We’ve seen great results for the treatment of white spot lesions by having our patient buy a tube of Fygg varnish and apply it to the inside of their retainers and wear nightly. Beyond impressed by the results!”
Common Questions
Everything you need to know before making the switch.
Most "natural" toothpastes still include foaming agents, preservatives, and essential oils that disrupt your oral microbiome. Fygg strips all of that out. Our formula contains only what's needed to remineralize teeth and nourish beneficial bacteria—nothing more. It's the "less is more" approach, formulated by two functional dentists who spent years scrutinizing what the industry gets wrong.
Hydroxyapatite is the mineral that makes up 97% of your tooth enamel and 70% of dentin. In nano-sized form (n-HAp), it can bond directly to teeth, filling micro-cracks and rebuilding weakened enamel. It's been used in Japan for cavity prevention since 1978 and is backed by extensive clinical research as a safe, effective alternative to fluoride.
Yes. It's biocompatible—meaning your body recognizes it as its own material. Unlike fluoride, there's no toxicity risk from swallowing. Fygg uses nanoXIM from Fluidinova in Europe, the gold standard for dental-grade n-HAp, at clinically optimal concentrations (1–3% nanoXIM per tube).
Nano-hydroxyapatite delivers the same remineralization benefits as fluoride without the concerns around toxicity, fluorosis, or endocrine disruption. Clinical studies show n-HAp is equally effective at preventing cavities and reducing sensitivity—so there's simply no need for fluoride in the formula.
Most toothpastes foam because of SLS (sodium lauryl sulfate), a detergent that strips your mouth of beneficial bacteria and can cause canker sores. Fygg is SLS-free. The clean feeling comes from the ingredients actually working—not from soap-like suds. It takes a couple days to adjust, but customers say their mouth has never felt cleaner.
Absolutely—sensitivity is one of the key issues n-HAp addresses. The nano-sized particles fill exposed dentin tubules, which are the tiny channels that transmit pain signals. Many customers report noticeable relief within the first week.
Yes. All flavors are fluoride-free, so there's no risk from accidental swallowing—making them safe for kids of all ages. Mild Mint is gentle enough for young brushers, and Vanilla Vibes, Coconut Cream, and Chocolate Swirl are especially popular with children.
Fygg was created by dentists—Dr. Mark Burhenne and Dr. Staci Whitman, both leaders in functional and holistic dentistry. It's also recommended by a growing number of practitioners who prioritize oral microbiome health and evidence-based, non-toxic ingredients.
Each 4oz tube lasts approximately 2–3 months with twice-daily brushing. The 3-Pack with Subscribe & Save is the most popular option—15% off and one less thing to remember.
We offer a 30-day satisfaction guarantee. If you don't love it, reach out to our team and we'll make it right—no questions asked.

"I’ve been using FYGG prebiotic toothpaste for about a week now and I am loving it. The taste is delightful and the texture is good too. It’s nice and smooth. For some it may be strange getting used to the no foam aspect, but I’ve been using more natural toothpastes for years so that doesn’t bother me at all. My teeth & mouth feel happy! Thanks a million FYGG fam!"
"We love this new toothpaste. I am an ingredient gal and believer that just because toothpaste has been the same forever, doesn’t mean it’s always right. It’s feels very good understanding the ingredients in FYGG toothpaste. I’ve only tried the mild mint flavor, but we are happy with it and now have an auto subscription. The non-foaming texture takes a moment to get used to, but at this point my husband and I like it more? And teeth feel good and smooth after use. Also no red flags at the dentist since we’ve made the switch. I also think it’s helping with my sensitivity."
"I like this toothpaste, and I dabbed a little extra on sensitive spots before I got the stronger stuff. It helped! I admit that I would like a little more minty zing to the flavor, but I appreciate the prebiotics."
"I have geographic tongue and this toothpaste has helped SO much! My highest recommendation!!"
"I wasn’t certain when I first started using FYGG, but now that I’ve been using it for over a year, I have to say—I am ruined for any other toothpaste. Once I got used to the mild taste, the unique texture, and the way it makes my mouth feel clean without foaming, I found I couldn’t go back. Any other toothpaste tastes too strong and artificial and gummy now. Anyway, I highly recommend this toothpaste. The mild mint and coconut cream are my favorites for everyday use, but the chocolate is delicious every now and again. I kind of wish a subscription option existed that would allow you to change flavors. But regardless, this toothpaste is unique and amazing and I will be using it for the foreseeable future."
"Expensive ! But it will be so well worth it if it helps my teeth, which have tended to gumline cavities, and now that I'm in my 70s, recession. Sensitivity I'd been having between two teeth has gone away, pretty much entirely, after a couple of weeks. Bravo ! I love the mildness of the taste, and when I went back to try a toothpaste I'd been using for months (another nano hydroxyapatite brand, grin pro from NZ), I found the mint flavor WAY too strong."
"Fygg is by far the best toothpaste I’ve ever used! It feels incredibly light and smooth, and best of all, it has a minimal ingredient list. It gives my teeth and microbiome exactly what they need to stay healthy, without any of the extra fluff."
"Fygg is a new experience for me. I’ve tried many homemade and Hydroxyapatite toothpastes, but I was not convinced about the power of its main ingredient. Well, I’m a believer now! My gums are receding and I have many filled and replaced teeth, so what I have left are precious. The whitening, without bleaching, and how clean my teeth get, without hurting, has been addressed by Fygg! Thank God, and Fygg!"
"Honestly, this toothpaste is expensive and after trying for a few weeks, you realize there isn’t much toothpaste in the tube. I was on a subscription, but not sure I’ll continue. One tube would never last a month."
"Hi, Well, I'm a bit sad that there is so much sugar, Monk Fruit, in it. It really doesn't need to be so sweet. Then the instructions say to leave it on your teeth, so in essence, at night when I brush my teeth and leave it on, I'm leaving a sugar on my teeth. I don't see how that is very helpful. I'm not sure I can see how the other stuff is benefiting me. I'm worried about the monk fruit factor. I hope it's as good as you say. I'll keep using, but not liking the sweetness. Sorry. . . Thanks for everything you do."
