Hydroxyapatite
What is Hydroxyapatite?
Hydroxyapatite is a naturally occurring mineral form of calcium apatite. It is the main component of tooth enamel and bone and can be synthetically produced for industrial and healthcare purposes.
In dental care products, hydroxyapatite helps to remineralize tooth enamel and can be used as an alternative to fluoride in toothpaste and mouthwash. Some studies suggest it is effective for reducing tooth sensitivity and improving overall oral health. However, evidence is still being gathered on its long-term benefits versus traditional fluoride treatments.
When found in a product label, hydroxyapatite is typically used for its potential advantages in oral health, aiming to strengthen teeth and prevent decay.
Commonly found in: Toothpaste, Mouthwash, Whitening products, Synbiotics
Benefits
- Helps remineralize and strengthen tooth enamel.
- May reduce tooth sensitivity when used in oral care products.
Hydroxyapatite is generally recognized as safe for use in dental care products.
Some research supports its effectiveness in enamel remineralization, though long-term comparisons with fluoride are still limited.
Synthetically produced hydroxyapatite is typically vegan, but consumers should verify the source.

The fluoride-free gold standard. A biomimetic mineral that closely matches the structure of natural tooth enamel, actively rebuilding micro-cracks and reducing sensitivity. Clinically equivalent to fluoride for cavity prevention without the neurotoxicity concerns.
