Can You Use Eggshell-Derived Nano-hydroxyapatite if You Have an Egg Allergy?
by Eunice Adegbaju on Sep 14 2026
An egg allergy is a reaction to egg proteins, and eggshell-derived nano-hydroxyapatite is a mineral made under heat high enough that no protein survives it. But "should contain none" is not the same as "was tested on you" — so if you have a diagnosed egg allergy, this is a conversation for your allergist.

Is Eggshell Nano-Hydroxyapatite Made From Real Eggshells?
by Eunice Adegbaju on Sep 14 2026
Eggshell nHAp is nano-hydroxyapatite made from real chicken eggshells rather than built from scratch in a lab. The shells are cleaned, heated, and reacted with a phosphate source until their calcium becomes hydroxyapatite — the same mineral your tooth enamel is made of.

Are Bones and Teeth Made of the Same Mineral?
by Eunice Adegbaju on Sep 14 2026
Your bone and the outer layer of your teeth are built from the same raw material. That material is hydroxyapatite — a calcium phosphate crystal. It makes up roughly 65–70% of bone by weight and the large majority of dentin and enamel. So when a dentist says you have "strong enamel," what they really mean is that a lot of hydroxyapatite is still packed into the surface of your teeth.

Why Do Surgeons Coat Implants With Hydroxyapatite?
by Eunice Adegbaju on Sep 14 2026
Surgeons coat titanium dental implants and artificial joints with hydroxyapatite because bone doesn't merely tolerate this mineral, it grows into it. Hydroxyapatite is what bone and enamel are already built from, so the body responds to a coated implant as something to bond with rather than wall off. It's called biointegration.

What Does "Biomimetic" Mean in Toothpaste?
by Eunice Adegbaju on Sep 14 2026
Biomimetic means "copies biology." In toothpaste, it describes an ingredient built to match what your teeth are already made of. Nano-hydroxyapatite is the clearest example: it's the same mineral as your enamel, made at the same microscopic size so your teeth recognize it.
