Hydroxyapatite Toothpaste

Hydroxyapatite is a naturally occurring mineral made up of calcium and phosphate — the same materials that form tooth enamel, dentin, and bone. When brushed onto the teeth, it fills microscopic surface imperfections and supports the body’s natural remineralisation process. The result is a smoother, stronger enamel surface that helps protect against sensitivity and decay.

Different forms of hydroxyapatite exist — mainly micro and nano — each referring to the particle size. Bliss Energetics uses the micro form, derived from natural fossilised coral, which you’ll learn more about below.

Hydroxyapatite toothpaste provides a gentle, fluoride-free way to maintain oral health while strengthening and protecting enamel.

Key benefits include:

• Supports the natural remineralisation of enamel
• Helps reduce tooth sensitivity
• Smooths and strengthens the enamel surface
• Promotes a clean, polished feeling after brushing
• Fluoride-free and biocompatible with the body
  

Because it mirrors the mineral composition of human enamel, hydroxyapatite works harmoniously with the body — offering a natural path to strong, healthy teeth.

Most studies show that hydroxyapatite toothpaste is effective at concentrations between 5 % and 10 %, leading to measurable improvements in enamel strength and sensitivity reduction.

However, concentration alone isn’t everything — the source, purity, and particle size are equally important.

Bliss Energetics uses a higher level — 20 % Coral Micro-Hydroxyapatite, sourced from fossilised coral. This unique material is rich in trace minerals that naturally support the body’s regenerative processes. The micro-sized particles stay safely within the mouth while providing thorough enamel coverage and long-lasting mineral contact.

Bliss chooses this natural, coral-based form because it’s both biocompatible and effective — a balanced approach between science and safety that avoids reliance on synthetic nano particles.

Yes — multiple studies have found that hydroxyapatite toothpaste performs as effectively as fluoride toothpaste in protecting enamel and reducing decay risk. It supports the body’s own ability to rebuild and smooth the enamel surface, helping to maintain strength and shine over time.

For deeper nourishment and targeted enamel support, hydroxyapatite toothpaste can be paired with Bliss Energetics’ Remineralising Tooth Putty — a natural mineral spot treatment that delivers concentrated minerals exactly where they’re needed most. Used together, they form a simple yet powerful daily routine for strengthening and restoring enamel health.

As can be seen below…

Hydroxyapatite is highly biocompatible — the body recognises it as its own mineral. The U.S. Food and Drug Administration (FDA) classifies calcium phosphates (which include hydroxyapatite) as “Generally Recognised as Safe (GRAS)”, and it has long been used in medical and dental applications such as bone grafts and implant coatings.

However, the European Union’s Scientific Committee on Consumer Safety (SCCS) has raised concerns about the safety of nano-hydroxyapatite — the synthetic, ultra-fine form used by some brands. The SCCS notes that current data are insufficient to rule out possible genotoxic effects (DNA-level damage) and therefore cannot confirm nano-HA’s safety for oral-care use at present concentrations.

Some laboratory studies have also reported potential cellular stress in kidney and blood cells linked to nano materials.

In contrast, non-nano (micro) hydroxyapatite, like the coral-derived form used by Bliss Energetics, remains within the oral environment and is regarded as safe, stable, and biocompatible. It allows you to enjoy the full benefits of enamel remineralisation — without the uncertainties associated with nanoparticles.
