What is hydroxyapatite - and why does it matter?
Hydroxyapatite is the same mineral that makes up most of your tooth enamel. That’s why it has become a leading fluoride alternative in natural toothpastes. Rather than simply forming a protective layer, it helps replenish weakened enamel by mimicking its natural structure and supporting remineralization – helping answer the question: does fluoride-free toothpaste actually work? Yes, when it is formulated properly.
Micro vs. nano - what we use
You may come across nano hydroxyapatite. At Green Beaver, we use micro-sized hydroxyapatite, which stays on the surface of the tooth to help fill tiny imperfections and reinforce enamel - delivering mineral-based protection without the concerns some consumers have around nano ingredients.
What are the benefits?
With regular use, hydroxyapatite helps:
- Strengthen and protect enamel
- Smooth the tooth surface
- Reduce the appearance of surface stains
- Support sensitive teeth (without harsh abrasives)
We also pair it with xylitol to help reduce plaque-causing bacteria and support overall oral health.
Choose the right formula for you
We offer two targeted options:
Both are fluoride-free and designed for adults. While hydroxyapatite is naturally occurring, these formulas are not meant to be swallowed.
