What Real Smiles Are Saying
US VS. THEM COMPARISON
Not another harsh mouthwash or temporary fix. Just dentist-developed pH science that actually prevents cavities.
Hey, I'm Dr. Toni – a dentist, founder of OralAdvance Labs and creatorof CariSpray
The moment that changed everything happened during a routine checkup. A 6-year-old named Luna needed her third filling in just one year. As I prepped the drill, her mom's voice cracked: "Doctor, I don't understand. We brush morning and night with fluoride toothpaste. We cut back on snacks and juice. I even bought those expensive kids' vitamins. What else can I possibly do?"
Any last questions?
What is CariSpray?
What is CariSpray?
CariSpray is the world’s first nano-hydroxyapatite oral spray, creating an entirely new category of oral care. It works through a triple mechanism: restoring pH balance, promoting microbiome optimization via xylitol, and enabling molecular-level tooth remineralization
Is it safe to swallow?
Is it safe to swallow?
Yes. CariSpray is completely safe to
swallow.
The enamel on your teeth is composed of approximately 97% hydroxyapatite, and CariSpray’s 0.45% nano-hydroxyapatite concentration is carefully designed to replace the minerals your teeth naturally lose each day from dietary acids.
Since these are biocompatible minerals already found in your body, swallowing the product poses no risk. No rinsing is necessary.
Where do you source your nano-hydroxyapatite?
Where do you source your nano-hydroxyapatite?
OralAdvance partners with FLUIDINOVA,
Europe’s leading manufacturer of high purity, research-grade nano hydroxyapatite.
Key material specifications: Sub-100 nm rod-shaped particles 98% dentin tubule occlusion (vs. 82% for competitors) RDA <10 (extremely low abrasivity) Pharmaceutical-grade purity
What type of nano-hydroxyapatite do you use?
What type of nano-hydroxyapatite do you use?
We use the only nano-hydroxyapatite approved by the EU's Scientific Committee on Consumer Safety as entirely safe, biocompatible, and non-toxic.
What makes this differentfrom adult CariSpray?
What makes this differentfrom adult CariSpray?
CariSpray Kids uses calcium and phosphate minerals particles sized specificallyfor developing teeth, child-safe concentration levels, and natural fruitflavors kids actually want. The formulation is optimized for the unique needsof growing permanent teeth.The adult formulation have nano-hydroxiapatite.
Does CariSpray actually work?
Does CariSpray actually work?
Yes – both clinical and laboratory studies confirm its effectiveness.
30-Day Use Study Results:
✓ 84% less staining
✓ 73% less tartar buildup
✓ 82% of users said their teeth looked whiter and brighter
✓ 100% found it easy to use
Laboratory Findings:
• 62% improved cavity protection within just 3 minutes
FLUIDINOVA Independent n-HA Research:
• Complete dentin tubule sealing within 7 days
• Sustained remineralization even after acid exposure
• Electron microscopy confirms nano-hydroxyapatite particle integration into
the enamel microstructure
Why 0.46% nano-hydroxyapatite?
Why 0.46% nano-hydroxyapatite?
Research shows that up to 10–14% of enamel hydroxyapatite can be lost during cavity development in typical caries models lasting 15–30 days. This translates to an average daily mineral loss of approximately 0.67–0.93%.
The 0.46% n-HA concentration in CariSpray is precisely formulated to replace this daily loss and maintain optimal mineral balance.
Howlong before I see results?
Howlong before I see results?
Results occur at multiple levels: Immediate: Fresh breath and cleaner
mouthfeel Within days: Improved oral pH balance After 2–4 weeks: Noticeable enamel smoothness and reduced sensitivity Long-term: Sustained remineralization
and caries prevention
How quickly does CariSpray work for sensitive teeth?
How quickly does CariSpray work for sensitive teeth?
Clinical data show measurable results
within days: Immediate: Fresh breath and cleaner mouth sensation
1 week: 35% reduction in tooth
sensitivity
2–4 weeks: Up to 80% reduction in
sensitivity
6 months: Up to 62% reduction in
long-term hypersensitivity
As validated in FLUIDINOVA’s independent
research.
Does CariSpray whiten teeth?
Does CariSpray whiten teeth?
Yes. Clinical imaging demonstrates natural
whitening through remineralization.
Electron microscopy shows nano hydroxyapatite particles smoothing the enamel surface, which enhances light reflection.
Studies confirm that 50 nm particle sizes deliver optimal whitening and structural integration, as validated in FLUIDINOVA’s independent research.
Why NANO ( Hydroxyapatite) ?
Why NANO ( Hydroxyapatite) ?
Because it mimics nature. Enamel and dentin naturally contain hydroxyapatite crystals about 40 nm in size. Our particles
(<100 nm) are engineered to mirror this biological architecture, allowing them to bond seamlessly to the tooth surface for true biomimetic remineralization.
What makes CariSpray different from other products?
What makes CariSpray different from other products?
CariSpray is the first oral
spray to combine:
pH balance restoration
Xylitol-driven microbiome optimization
Molecular-level enamel remineralization
This triple-action approach revolutionizes
preventive dental care.
Is it safe for families?
Is it safe for families?
Yes. Suitable for ages 6 and up, our
n-HA is SCCS-approved, 100% non toxic, paraben-free, vegan, and NATRUE-certified.
Why is CariSpray more expensive than regular mouthwash?
Why is CariSpray more expensive than regular mouthwash?
CariSpray’s formula was developed from
years of research and clinical validation.
Compared to the cost of a single dental filling and other dental procedures, Carispray offers far greater long-term savings and protection.
What if it doesn’t work for me?
What if it doesn’t work for me?
We offer a 30-day money-back guarantee.
This window exceeds most dental treatment periods, providing enough time for measurable remineralization and relief outcomes to occur.
