Fygg Toothpaste FAQs

No harsh chemicals, no fluoride and featuring the highest quality on the market and using the only nano-Hydroxyapatite that is approved for consumer safety by the SCCS in the EU nano-Hydroxyapatite, Fygg was designed to promote a healthy oral microbiome while protecting your teeth. Other toothpastes include unnecessary and potentially harmful ingredients like foaming agents, preservatives and other powerful chemicals. Fygg's prebiotic mineral toothpaste contains only what is required to remineralize teeth and support the oral microbiome, which is what toothpastes should have been engineered to do from the very beginning.

An oral microbiome supportive remineralizing toothpaste without surfactants, emulsifiers, fluoride, and excessive essential oils. Simple. Effective. Safe. This is what makes Fygg unique. 

We are a “less is more” brand. Founded by two whole-body, functional dentists who have scrutinized the industry, the research, and the efficacy of the competition for years, our formulations have been labors of love and made with genuine passion for creating a better and cleaner product. We were able to successfully remove the unnecessary ingredients that the industry has long included in their toothpastes solely for cheaper and more efficient methods of mixing large batches of toothpaste. Removing these ingredients allows us to manufacture a paste that tastes good, feels good, actually works, and does not cause harm. Nourishing the oral microbiome and remineralizing teeth; this is what toothpaste should be.

Hydroxyapatite is a naturally-occurring mineral composed of calcium and phosphate, the same mineral that makes up to 97% of the enamel of your teeth and 60-70% of your bones. It has been used for decades in the medical, dental, and cosmetic industries for its unique properties. Our toothpaste contains a carefully balanced blend of the purist nano Hydroxyapatite available on the market, making it extremely effective. Hydroxyapatite provides a protective layer to help remineralize and strengthen your teeth, while also helping to reduce the formation of plaque, and making teeth appear whiter and feel smoother. Hydroxyapatite can also help to reduce sensitivity and improve the overall health of your teeth and gums by supporting your oral microbiome.

Here is the latest research on hydroxyapatite.

Yes, nano-Hydroxyapatite (nano-HAp) has been used in toothpaste for over four decades in countries such as Japan and Italy. In March of 2023, the SCCS in Europe announced its final decision regarding nano-HAp, stating that based on the data provided, the SCCS considers hydroxyapatite (nano) safe when used at concentrations up to 10% in toothpaste, and up to 0.465% in mouthwash. An update in June 2023 emphasizes the importance of using particles with certain aspect ratios.

Fygg’s nano-HAp source is currently the only SCCS-approved nano-HAp, meeting or exceeding all SCCS guidelines regarding nano-HAp concentration, particle size, aspect ratio, and shape. The SCCS safety evaluation only applies to the hydroxyapatite (nano) with the following characteristics:

- composed of rod-shaped particles of which at least 95.8% (in particle number) have an aspect ratio less than 3, and the remaining 4.2% have an aspect ratio not exceeding 4.9;

- the particles are not coated or surface modified.

Yes! Thank goodness!

Absolutely not! We are major animal lovers over here at Fygg.

Excessive fluoride has been deemed toxic to the fetal and infant brain and it is unnecessary for proper oral health. No one is fluoride deficient. Fluoride is not an essential nutrient, nor is it needed for cavity prevention and optimal oral health. Toothpaste containing fluoride has a poison control label on it and for good reason…it can increase the risk of dental and skeletal fluorosis, which is a condition that causes discoloration and mottling of the teeth and weakened bones, respectively. Additionally, over 70 studies have shown excessive amounts of fluoride in pregnancy and early childhood are linked to a decrease in IQ, not to mention a slew of other health concerns associated with fluoride consumption, such as it’s impact on the thyroid. It has no business in our bodies or in our products. Research shows hydroxyapatite (a mineral naturally found in our teeth and bones) to be as effective, with some data showing it outperforming fluoride. Seems like a no-brainer to us.

The founders are both dentists, so absolutely! Beyond Dr. B and Dr. Staci, dentists world-wide are embracing hydroxyapatite-based toothpastes and suggesting it to patients as a first line of defense for remineralization and to help with sensitivity and whitening.

It is wonderful for sensitive teeth! Hydroxyapatite has been shown to help with not only remineralization, but also sensitivity in the research.

Without all the fillers, additives, surfactants, and emulsifiers you see in other toothpastes, the paste can sometimes slightly separate and small air pockets can form. Think of natural nut butters without emulsifiers and fillers...it separates, right? A quick massage of the tube prior to squeezing and/or storing it upright solves for this issue.

Science shows that hydroxyapatite works just as well at remineralizing teeth as fluoride, with some studies now showing nano-hydroxyapatite outperforming fluoride. In addition to remineralization, hydroxyapatite can make teeth less sensitive, smoother, brighter, and appear whiter, as well as nourish the oral microbiome by preventing plaque formation by pathogenic bugs and preventing pellicle formation. It also establishes ionic integrity which is needed for the natural exchange of mineral ions in the mouth.

Hydroxyapatite (HAp) can bind to microorganisms by interacting with the bacterial adhesin thus agglutinating bacteria and removing them from the oral cavity. HAp also blocks the pellicle receptors from binding to bacterial receptors. Remember, we are adding nano-HAp for optimal remineralization and desensitization and micro-hydroxyapatite for oral microbiome health and optimal salivary pH. This modulates biofilm thickness and health. Micro-hydroxyapatite does not remineralize as well as nano-HAp based on research, which is why we chose to use nano-HAp in our formula.

No. Fygg toothpaste contains a small amount of xylitol, which can be toxic to dogs. Dogs’ metabolism and lack of appropriate enzymes prevents them from properly digesting xylitol. We use xylitol for flavor and microbiome benefits, but it is not safe to use with pets. If your pet happens to find their way into your toothpaste, contact your Vet or Pet Poison Control immediately (1-800-213-6680).

Yes! We highly suggest it for patients with orthodontic appliances or dental restorations, as it can strengthen enamel, whiten teeth, and reduce sensitivity.

Nope! That would not be very oral microbiome supportive and therefore that's a no-go for us.

While personal results will vary, the research and clinical outcomes surrounding remineralization and hydroxyapatite are impressive. Along with using Fygg toothpaste daily, we suggest working with a knowledgeable Functional or Holistic Dentist to have a tailored program created for your individual needs.

You only need a small rice-sized amount of toothpaste for efficacy in kids, and a pea-sized amount for efficacy adults. The magic of the toothpaste is with it's ability to "super-charge" your saliva, so just a thin coating on your teeth is sufficient. You can spit, but DO NOT RINSE after more maximum efficacy!

Absolutely! In fact, it is able to help with any post-whitening sensitivity! However, we do recommend trying a nano-HAp-based toothpaste before trying whitening with trays and the peroxide-based oxidizing agent. Since nano-HAp does actually make teeth look whiter and brighter, many have found this to be enough of an effect. Peroxide-based whitening procedures are generally quite aggressive and not oral microbiome or tooth-friendly procedures.

As soon as teeth erupt, they can get cavities, so we suggest beginning a brushing routine as soon as your baby gets teeth. Wiping gums and the tongue before teeth erupt can help ensure pathogenic bacteria are not settling in your babies mouth and can help to desensitize for future oral hygiene routines. It's never too early to start an oral hygiene routine!

Xylitol is a sugar alcohol, which is a type of complex carbohydrate and does not actually contain alcohol. Xylitol occurs naturally in small amounts in fibrous fruits and vegetables, trees, corncobs, and even the human body. We use a non-GMO xylitol and its oral benefit has long been supported by studies for use in toothpastes and nasal sprays. Not only does it support the oral microbiome by reducing the stickiness of certain cavity-forming bacteria, it also tastes wonderful!

Consistent ingestion of excessive xylitol has seen some issues in the literature for those with gut microbiome dysbiosis. Swallowing excessive xylitol can also potentially raise uric acid levels, but the amount needed to accomplish this is far beyond what toothbrushing would contribute to and refers more to baking with and eating/drinking foods and drinks with xylitol daily. For toothpaste use, it is one standard that nearly all dentists can agree upon to help with oral microbiome integrity and for better cavity prevention based on the ample data and research. And it tastes great!

This answer all depends on how many teeth we are talking about. Younger children can aim for around one minute (try singing ABC’s!), whereas once all permanent teeth come in, we suggest shooting for a full two minutes. But remember, it is about quality over quantity!

There is no science to necessarily support this, but we feel the logical order for oral hygiene is to tongue scrape (once a day), floss (once a day), and then brush (twice a day). We also love adding in an oral probiotic at the end of your routine to add additional beneficial bacteria into the mouth. But beggars can’t be choosers, so please follow whatever order enables you to get the job done!

Not with our super-clean, oral microbiome supportive formulation! Do not rinse, just spit it out. This takes a little getting used to, but trust us when we say you will learn to love this effective habit. The magic of the prebiotics and hydroxyapatite will work best if left on the teeth and in your saliva, so please do not rinse all that goodness down the drain!

PRO TIP: Place a small smear of the toothpaste on your floss and floss it between your teeth, especially if you are told you have any smaller (incipient) cavities in between your teeth. And again, do not rinse!

Fygg has an RDA of 34.3, as determined through third-party testing.

Fygg Dental Varnish FAQs

Choosing Fygg prebiotic nano-HAp varnish over a traditional fluoride varnish is preferred by many providers and patients due to its science-backed properties, clean ingredients, and microbiome support, all while still maintaining comparable efficacy in terms of remineralization, desensitization, and whitening.

Fygg nano-HAp uses 15.5% nanoXIM at 57.34% concentration (8.6% nano-HAP), using what is currently the only form of nano-Hydroxyapatite (nanoXIM.CarePaste manufactured by Fluidinova) currently approved by the SCCS in Europe for safety and efficacy.

For dentists seeking to provide the safest, most effective, biomimetic, and oral microbiome-supportive dental care to patients of all ages, Fygg prebiotic nano-HAp varnish can be a beneficial addition to your dental practice, giving patients options for optimal oral health.

Yes! The appropriate concentrations and types of nano-Hydroxyapatite in Fygg varnish can be as effective in supporting remineralization, reducing tooth demineralization, and helping with sensitivity as fluoride varnishes. Several studies have shown that nano-Hydroxyapatite has similar or better efficacy as fluoride in remineralizing early carious lesions, preventing dental caries formation, and helping with sensitivity.

Check our our Varnish Page for more resources and research links.

With prebiotic fiber and L-Arginine, Fygg nano-Hydroxyapatite actively nourishes your patient’s oral microbiome, not destroying it as many other products do.  The prebiotic fiber in the formula will feed and nourish the beneficial bacteria in the mouth. L-arginine has shown to elevate dental plaque pH, inhibit biofilm formation, and destabilize biofilm structure.

Also, with the elimination of unnecessary oral microbiome disruptors, emulsifiers, surfactants, artificial flavors and sweeteners, hexanes and propylene glycol derivatives, and excessive essential oils, Fygg supports commensal and beneficial bacteria, allowing them to thrive! 

Check our our Varnish Page for more resources and research links.

Many dental professionals consider hydroxyapatite varnish to be safer than fluoride varnish due to fluoride being classified as a neurotoxin. We were able to remove hexane and propylene glycol derivatives from our varnish, making it a much cleaner choice for all patients and providers. 

Fygg's prebiotic nano-Hydroxyapatite varnish is applied similarly to fluoride varnish. The varnish is painted onto the tooth surface using a brush, a cotton swab, or a gloved finger, typically after a dental cleaning. The process is quick and easy, and patients greatly prefer the subtle taste and texture of Fygg varnish compared to the strong, astringent taste and overwhelming texture of fluoride varnishes.

Fygg's professional strength prebiotic nano-Hydroxyapatite varnish is applied by a dental professional, such as a dentist or dental hygienist.  Applications can occur during a routine dental check-up, following a cleaning appointment, or at a specific frequency as determined by the dental team to help with sensitivity, demineralization, and remineralization. This is a great choice for those looking to avoid fluoride, but still wanting oral microbiome and remineralization support.

Most dental professionals will apply it twice a year or based on recare frequencies and scheduling, but Fygg nano-Hydroxyapatite varnish can be applied at a higher frequency, depending on a patient’s needs. Custom trays can be made for home use based on the dental professional’s diagnosis and discretion.

Patients with extensive decay, especially smooth surface or root caries, orthodontic white spots lesions, or chronic tooth sensitivity may benefit from at-home use in custom trays that they wear at night, but this should be recommended based on a dental professional's diagnosis and discretion. 

Hydroxyapatite varnish may vary depending on your specific insurance plan. It is recommended to check with your insurance provider for details on coverage and reimbursement. We are working hard behind the scenes to have hydroxyapatite varnishes covered universally soon! A new CDT was released in January 2024 (D2991: application of hydroxyapatite regeneration medicament) and we are hopeful the important recognition that hydroxyapatite can regenerate tooth structure will help to get this service covered for more and more patients very soon!

Patients and providers alike are loving Fygg's prebiotic nano-Hydroxyapatite varnishes and they taste infinitely better than a fluoride varnish!  Our varnish has far less of an undesirable aftertaste and texture due to removing unnecessary and potentially harmful chemicals like hexanes, propylene glycol, and polyurethane derivatives. You will find a lot fewer tears, nausea, and vomiting (aka: no “fluoride face!”) after the application of Fygg prebiotic nano-Hydroxyapatite varnish.

While Fygg does not have the ADA seal of approval because the ADA will not approve anything without fluoride in it, there is some good news on the horizon—the ADA launched a new CDA code in January 2024 for hydroxyapatite varnishes, which makes us feel hopeful that the ADA will start approving hydroxyapatite products soon.

The truth is, many oral care ingredients, including fluoride (yes, fluoride!), lack ADA and FDA approval for certain uses, and we use them off-label. This doesn’t mean fluoride or hydroxyapatite don’t work—instead, it highlights the evolving landscape of oral health research and regulation.

The FDA's stance on off-label use underscores the importance of informed decision-making and responsible usage by healthcare professionals. Practitioners are encouraged to rely on scientific rationale and medical evidence when utilizing products for purposes beyond their approved labeling. FDA approval is not required to use fluoride varnish off-label. (USFDA, 1998, USP DI, 2006) In summary, the absence of FDA approval for hydroxyapatite doesn't diminish its effectiveness or safety. Instead, it underscores the need for a nuanced understanding of oral care ingredients and their applications.

Yes, Fygg's prebiotic nano-Hydroxyapatite varnish can promote remineralization, prevent tooth demineralization, help with sensitivity, and brighten and whiten smiles in patients of all ages.
