A standard query I get is whether or not hydroxyapatite is FDA permitted. The quick reply? No, it’s not. However let’s delve deeper into why that’s and what it means for you.
Conventional fluoride varnishes, typically utilized in dental workplaces, have garnered FDA approval as Class II Medical Gadgets.
Nonetheless, it’s essential to grasp that this approval pertains to their use as cavity liners and tooth desensitizers, not as caries preventive brokers.
In reality, fluoride varnishes are steadily utilized “off-label” for caries prevention, a follow permitted by the FDA.
Why isn’t hydroxyapatite FDA permitted for dental use but?
Hydroxyapatite is FDA permitted for medical purposes, however not but dental. In the US, the Meals and Drug Administration (FDA) doesn’t enable cavity-fighting claims for toothpastes that don’t have fluoride.
The reality is, many oral care elements, together with fluoride (sure, fluoride!), lack FDA approval for sure makes use of, and we use them off-label. This doesn’t imply fluoride or hydroxyapatite don’t work—as a substitute, it highlights the evolving panorama of oral well being analysis and regulation.
The FDA’s stance on off-label use underscores the significance of knowledgeable decision-making and accountable utilization by healthcare professionals. Practitioners are inspired to depend on scientific rationale and medical proof when using merchandise for functions past their permitted labeling. FDA approval shouldn’t be required to make use of fluoride varnish off-label. (USFDA, 1998, USP DI, 2006)
In abstract, the absence of FDA approval for hydroxyapatite doesn’t diminish its effectiveness or security. As a substitute, it underscores the necessity for a nuanced understanding of oral care elements and their purposes.
Many medicines are at the moment prescribed and administered for off-label use, and lots of medicine utilized in medical follow for kids have by no means been examined in youngsters. The FDA regulation states: “Good medical follow and the very best pursuits of the affected person require that physicians use legally obtainable medicine, biologics and gadgets based on their finest data and judgment. If physicians use a product for a sign not within the permitted labeling, they’ve the accountability to be well-informed in regards to the product, to base its use on agency scientific rationale and on sound medical proof, and to take care of information of the product’s use and results.” (USFDA, 1998; AAP, 2002)

So, within the absence of FDA-approval, what must you search for in a hydroxyapatite toothpaste?
The FDA at the moment regulates toothpaste as a beauty product, which I imagine is inadequate for a product that instantly impacts the oral microbiome and whole-body systemic well being. To not point out, it’s used twice a day for all times.
Within the absence of regulation, these are the standard requirements that I’ve give you to determine client efficacy, well being, and security, and I encourage you to share these extensively together with your sufferers, buddies, or household.
1. Does it work on tooth?
Peer reviewed research are the gold customary, as we all know. A number of peer-reviewed research have demonstrated the efficacy of hydroxyapatite for caries, sensitivity, and even whitening.
The Environmental Working Group has given hydroxyapatite a 1/10, discovering that hydroxyapatite shouldn’t be suspected to be an environmental toxin, not anticipated to be doubtlessly poisonous or dangerous, and never suspected to be bioaccumulative: https://www.ewg.org/skindeep/elements/703046-HYDROXYAPATITE/
2. Is it secure for the remainder of the physique?
In dentistry, we have now a foul behavior of specializing in simply the tooth and neglecting the influence of medicine and medicines on systemic well being.
Because of this I look to the SCCS ruling, because the SCCS is like an FDA however with stricter requirements, they usually have assessed hydroxyapatite’s influence on systemic well being. As of this writing, the one hydroxyapatite on the earth that meets the rigorous requirements supplied by the SCCS remaining opinion on March 2023 is Fluidinova, made in Portugal, and this is among the causes we selected Fluidnova because the supply of hydroxyapatite for all of our toothpastes and varnishes at Fygg.
From the SCCS Remaining Opinion on nano-Hydroxyapatite, March 2023, web page 3:
The SCCS concludes the next:
1. In view of the above, and making an allowance for the scientific information supplied, does the SCCS contemplate hydroxyapatite (nano) secure when utilized in oral beauty merchandise based on the utmost concentrations and specs as reported within the submission, making an allowance for moderately foreseeable publicity situations?
Based mostly on the information supplied, the SCCS considers hydroxyapatite (nano) secure when used at concentrations as much as 10% in toothpaste, and as much as 0.465% in mouthwash.
This security analysis solely applies to the hydroxyapatite (nano) with the next traits:
– composed of rod-shaped particles of which no less than 95.8% (in particle quantity) have a facet ratio lower than 3, and the remaining 4.2% have a facet ratio not exceeding 4.9;
– the particles should not coated or floor modified.
Will the FDA approve hydroxyapatite sooner or later?
Despite the fact that hydroxyapatite toothpaste and polish should not FDA-approved, there’s optimistic motion ahead:
In 2024, the CDT adopted new codes for using hydroxyapatite varnishes:
D2991 Utility of hydroxyapatite regeneration medicament – per tooth
1. When lined, process D2991 is a profit twice per tooth per profit yr. Advantages for greater than twice per tooth per profit yr are denied and are the affected person’s accountability.
2. The charges for D2991, on the identical tooth and on the identical date of service as a restoration, should not billable to the affected person on the similar dentist/dental workplace.
Actions into new supplies and procedures take time. We noticed this with the motion away from alloy fillings and with the implementation of SDF, and we’re assured hydroxyapatite will likely be acknowledged quickly.
Within the meantime, what are you able to do?
Whether or not you’re a affected person or a practitioner, if you’re captivated with this subject, I encourage you to write down letters to insurance coverage corporations and the FDA. My colleague and associate at Fygg, Dr. Staci Whitman, shared with me a letter she’s written to the FDA, and I’ve included it beneath with permission as a template so that you can copy/paste and use your self when you select:
Instance letter urging insurance coverage corporations and/or FDA approval of hydroxyapatite
