Frequently asked questions
What is nano-hydroxyapatite (nHA)?
Nano-hydroxyapatite (nHA) is a biomimetic mineral that makes up most of your teeth and bones. It’s used in oral care to help rebuild enamel, reduce sensitivity, and protect teeth naturally.
What is nanoXIM® and why do you use it?
nanoXIM® is a premium form of nano-hydroxyapatite developed by FLUIDINOVA. Restore is made with
nanoXIM•CarePaste 15.5% concentration.
It’s engineered to closely mimic natural tooth mineral, making it highly effective for:
Enamel remineralisation
Sensitivity reduction
Surface repair and smoothing
Unlike generic nHA, nanoXIM has controlled particle size and shape, improving how well it bonds to teeth.
Is nanoXIM better than regular nano-hydroxyapatite?
Yes, we think so! Here's why:
- Higher purity and consistency
- Rod-shaped particles that adhere better to enamel
- Backed by extensive safety testing and regulatory approval
This leads to more reliable results compared to lower-quality or undefined nHA sources.
Where are your products manufactured?
Our hero ingredient nanoXIM is sourced from Portugal, Spain. However, it is manufactured in Melbourne, Australia.
Is this product suitable for children?
Yes, this product is generally suitable for children. However, in line with Australian oral health guidance, it is not recommended for use in children under 2 years of age unless advised by a dental professional.

Why is your formula fluoride-free?
Restore is formulated without fluoride for those who prefer a fluoride-free option. It uses nano-hydroxyapatite as an alternative ingredient in a gentle, everyday oral care formula.
The Founders of Restore toothpaste are both registered dental practitioners in Australia & they noticed more and more patients were wanting a fluoride free alternative. But they weren't happy with any of the natural toothpastes on the market. Then came Restore.
Why doesn’t Restore contain SLS (Foaming agent)?
Sodium lauryl sulfate (SLS) is commonly used in toothpaste to create foam. However, foam itself does not contribute to how effectively teeth are cleaned.
Some studies have suggested that SLS may contribute to irritation in certain individuals. For example, research has linked SLS-containing toothpaste with increased discomfort and longer healing time in people prone to recurrent mouth ulcers (such as Recurrent Aphthous Stomatitis).

There is also emerging research exploring how SLS may influence the oral environment. Laboratory and clinical findings suggest it can disrupt the balance of oral bacteria under certain conditions, highlighting the importance of considering overall formulation rather than relying on foaming agents alone.

Restore is formulated without SLS to provide a gentler, low-foaming brushing experience.
Does Restore Toothpaste affect the oral microbiome?
Restore is designed to be gentle on the oral microbiome.
This means it:
- Avoids harsh antibacterial agents that wipe out both good and bad bacteria
- Focuses on supporting a balanced oral environment
- Allows beneficial bacteria to remain part of the natural ecosystem
The goal is balance, not sterilisation.
Why does your oral microbiome matter for your whole body?
Your mouth has hundreds of bacteria that don’t just stay in your mouth. If the balance gets unhealthy, these bacteria and their toxins can enter your bloodstream.
Once in the blood, they can:
- Trigger long-term inflammation
- Contribute to fat buildup in arteries (atherosclerosis)
- Increase risk of heart attacks and stroke
Recent research shows people with gum disease are more likely to have cardiovascular disease, partly because of this ongoing inflammation and bacterial spread (- Harvard Health Medical).
