Hydroxyapatite vs Fluoride — What’s the Difference?

Hydroxyapatite vs Fluoride — What’s the Difference?

The Big Toothpaste Debate

For decades, fluoride has been the “gold standard” in toothpaste. But with growing concerns over safety and long-term health, people are searching for cleaner, safer alternatives. That’s where hydroxyapatite comes in — a naturally occurring mineral that’s transforming oral care.

Let’s break down the difference.

What Is Fluoride?

Fluoride is a mineral added to most mainstream toothpastes to help prevent cavities by making enamel more resistant to acid attacks. While it’s effective, fluoride can be problematic:

  • Excess fluoride may cause fluorosis (white spots on teeth).
  • Many people worry about its long-term impact on health.
  • It’s toxic if swallowed in large amounts.

What Is Hydroxyapatite?

Hydroxyapatite (HAp) is the natural mineral that makes up 97% of tooth enamel and 70% of dentin. Instead of coating your teeth like fluoride, it actually works to rebuild and remineralise your enamel on a cellular level.

Benefits include:

  • Strengthens enamel naturally
  • Reduces sensitivity
  • Non-toxic and safe to swallow
  • Supports a healthy oral microbiome
