"The strongest hydroxyapatite toothpaste — now with the data to prove it."
No burn, no foam, no fluoride
Our first-of-its-kind formula uses hydroxyapatite to strengthen and protect teeth, without the harsh foams and damaging essential oils found in other "natural" toothpastes. The result? Strong, naturally whiter teeth, and a healthier oral microbiome.
Clinically as effective as fluoride. No toxic side effects.
From essential oils to fluoride to foam, even "natural" toothpastes can harm the oral microbiome. So, our dentists decided to formulate their own.
Dr. Will Cole
“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.”
Dr. Mary Ellen Chambers
“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”
Carrie Jones
“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.”
Maggie Hill
“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!”
Noor A. Khaki
“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!”
Seth Gilson
“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.”
Jennifer Crowe
“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!”
