What is Hydroxyapatite?
Hydroxyapatite is a nature-identical mineral that closely matches the structure of tooth enamel - the protective outer layer of your teeth. Because it closely matches the composition of enamel, it is often described as biomimetic.
Red Seal Baking Soda + Hydroxyapatite (HAp) Toothpaste uses Micro-Hydroxyapatite, a particle size designed to stay on the surface of teeth during brushing. This allows it to support enamel health as part of everyday oral hygiene.
Formulated with nature-identical mineral particles, it is designed for daily use and for those who value clean, conscious oral care.
Two Key Ingredients for whiter looking teeth. One Everyday Formula.
This formula brings together baking soda and hydroxyapatite - two ingredients commonly used in oral care. Together, they help lift surface stains and support enamel mineralisation, contributing to brighter, whiter-looking teeth with regular brushing.
Baking Soda
• A naturally occurring alkaline compound
• A long trusted ingredient in oral care
• Helps lift surface stains with regular brushing
• Leaves the mouth feeling fresh
Hydroxyapatite (HAp)
• A naturally occurring mineral also found in enamel
• Makes up the majority of enamel structure
• Supports enamel mineralisation
• Whiter-looking teeth through surface smoothing
How It Works: Surface-Level Action on Teeth.
As you brush, the formula works at the surface of your teeth - helping to smooth enamel and enhance light reflection for a brighter, whiter-looking smile.
Micro-hydroxyapatite particles coat the tooth surface during brushing, supporting enamel mineralisation and helping to smooth the surface of teeth.
This smoothing effect improves how light reflects off enamel, contributing to a whiter-looking appearance.
When combined with baking soda, the formula also helps polish and lift surface stains as you brush, leaving teeth feeling clean and fresh.

What You Might Be Wondering
Is Hydroxyapatite a fluoride replacement?
No. Hydroxyapatite is an alternative cosmetic ingredient used in some toothpastes. It’s suitable for people who prefer a fluoride‑free option, but it is not positioned as a medical or therapeutic substitute.
Why combine Baking Soda with Hydroxyapatite?
Baking soda provides a polishing action for a deep clean feeling, while Hydroxyapatite helps smooth the tooth surface. Together, they help brighten and whiten teeth and leave your mouth feeling clean and refreshed.
Is Baking Soda + HAp toothpaste suitable for children?
Adults and older children (under adult supervision) can use it. For young children, follow standard brushing guidance and ensure they do not swallow toothpaste.
Does it Hydroxyapatite actually whiten my teeth?
Whiter looking teeth occur through surface polishing and light reflection, rather than chemical bleaching.
With regular brushing:
- Baking Soda polishes and lifts surface stains.
- Hydroxyapatite coats the tooth surface, enhancing light reflection.
- The whitening action works all through a surface-level, physical action, not a chemical bleaching process.
