Nano Hydroxyapatite Vs. Fluoride

Nano-Hydroxyapatite 

As a substitute for fluoride, commonly found in fluoride-free toothpaste, "Hydroxyapatite" or "Nano-Hydroxyapatite" has emerged as a promising option. While it shares similarities with fluoride in its ability to nourish and remineralize teeth, it takes a different approach that might offer a safer alternative. Let's delve deeper into this compound to gain a more comprehensive understanding and determine its compatibility with our bodies.

Interestingly, Hydroxyapatite is a natural component present within our bodies. Approximately 50% of our bones by volume and 70% by bone weight consist of this mineral. Recognized for its proven biocompatibility and its role as the primary element in bone and teeth mineralization, Hydroxyapatite has been extensively studied in the medical realm. In fact, it's utilized in crafting bone replacements due to its alignment with our natural bone structure, which is composed of Hydroxyapatite and collagen.

Possible concerns arise when we encounter issues like fluorosis or calcified pineal glands, as excessive calcification leads to an overabundance of Hydroxyapatite. Autopsies on individuals with calcified pineal glands reveal that the hardened substance blocking melatonin secretion is Hydroxyapatite. This blockade gives rise to various problems including dementia, Alzheimer's, and insomnia. It's important to note that this issue primarily stems from the excessive intake of fluoride. Fluoride causes Hydroxyapatite to solidify into calcium halophosphate [Ca5(PO4)3F]. This transformation into a hardened state occurs only in the presence of elevated fluoride levels. On its own, Hydroxyapatite is soluble and doesn't penetrate cell walls; it naturally dissolves and digests in the body. The calcification concerns manifest when fluoride-induced hardening takes place.

Moreover, Hydroxyapatite has been deemed safe by the European Commission's Scientific Committee on Consumer Safety (SCCS) for oral care use, with toothpaste granted a usage limit of 10% and mouthwash, 0.465%. To date, no instances of toxicity from Hydroxyapatite have been reported. In the context of dental health, nano-hydroxyapatite also acts as a filler, adeptly repairing small holes and depressions on enamel surfaces. The fine particle size further enhances its reparative function.

For individuals with sensitive teeth and susceptibility to cavities, Hydroxyapatite may emerge as a valuable and substantially safer alternative to fluoride, offering both strength and potential repair. However, balance is paramount. While Hydroxyapatite has been certified as non-toxic and naturally present in our bodies, excessive exposure to any substance can prove detrimental. (of course if you’re chugging it like a preschooler obsessed with glue for whatever reason, you’ll likely run into problems). Unlike fluoride though, Hydroxyapatite isn't being introduced into our water or foods, and ingesting it doesn't carry the drawbacks or dangers the way fluoride does. In fact, its non-toxic nature renders it less susceptible to overexposure risks.

In conclusion I would consider hydroxyapatite as a safe substance and wouldn’t shy away from seeing it in my tooth paste. Of course if you still want to turn away from it, there are options without it as well.
