For decades, we’ve reached for the same brands when it comes to toothpaste – bright packaging, familiar flavours, promises of whitening power. But if you’ve found yourself wondering why your smile isn’t quite as bright as you hoped, or how to whiten your teeth without harsh chemicals, there’s one ingredient you probably haven’t heard of yet.
It’s called hydroxyapatite, and it’s quietly reshaping how we care for our teeth, one tube at a time.
What is hydroxyapatite?
Hydroxyapatite is a naturally occurring mineral that makes up about 97% of your tooth enamel and 70% of dentin, the layer beneath. It’s also found in your bones.
Scientists first began studying hydroxyapatite in dentistry back in the 1970s, when NASA used it to help astronauts counteract mineral loss in space. Since then, it’s been widely adopted in Europe and Japan for remineralising and repairing tooth enamel.
Now, more people around the world are turning to hydroxyapatite toothpaste as an alternative to fluoride that mimics the mineral structure of real teeth.
Can hydroxyapatite whiten teeth?
Yes it can, but not in the way most traditional whitening products do.
Most mainstream whitening toothpastes use abrasive particles or bleaching agents like hydrogen peroxide to lift surface stains. While this can create short-term results, there are often downsides like increased tooth sensitivity.
Hydroxyapatite takes a restorative approach. Instead of stripping your enamel, it works through:
-
Remineralisation: HAP particles integrate into the enamel, filling micro-defects and helping to restore natural lustre
-
Surface smoothing: Repairing enamel irregularities helps to create a smoother surface that reflects light more uniformly, enhancing brightness.
- Stain removal: HAP exhibits mild abrasiveness, aiding in the gentle removal of surface stains without damaging enamel.
A 2023 review of 17 studies found that, “It can be concluded that regular use of hydroxyapatite-containing oral care products effectively whitens teeth, but more clinical trials are required to support the preliminary in vivo evidence.”
Hydroxyapatite toothpaste has been approved for use in Japan, the EU and Canada for many years. If you’re seeking long-term teeth whitening that supports oral health rather than undermines it, hydroxyapatite could be a breakthrough worth exploring.
Benefits of hydroxyapatite
Hydroxyapatite is biocompatible, non-toxic, and already a part of your body’s natural structure.
It’s especially popular among:
- People with sensitive teeth
- Parents looking for a fluoride-free option for children
- Anyone who wants a more holistic approach to dental care.
Clinical studies show that hydroxyapatite is just as effective as fluoride for remineralising enamel and preventing cavities.
Which oral health products contain hydroxyapatite?
Many of the world’s largest toothpaste brands still don’t include hydroxyapatite in their formulations. Instead, they rely on legacy ingredients, mass-market appeal, and abrasive whitening methods.
That’s why smaller, more innovative brands are stepping up.
At Myospots, we’ve formulated a hydroxyapatite toothpaste designed to:
- Remineralise enamel
- Gently reduce sensitivity
- Promote long-term teeth whitening
- Avoid harsh ingredients like SLS, triclosan, and peroxide.
It’s fluoride-free, made with seashell derived ingredients, and suitable for the whole family, including kids.
