Revives your smile’s natural shine without harsh abrasives.
Smooth and Relief
Gently soothes irritation and keeps teeth feeling silky smooth.
Advanced Enamel Support
Helps maintain tooth health and keeps teeth strong.
Sensitivity Support
Calms sensitive teeth while reinforcing enamel defenses.
Enamel Remineralization
Strengthens and rebuilds tooth enamel for lasting protection.
Smooths & Protects
Creates a protective barrier to help maintain healthy teeth and support strong enamel.
CariSpray scientifically-backed formula contains:
- Nano-Hydroxyapatite: The same mineral that makes up 97% of your tooth enamel. It remineralizes and strengthens teeth at the molecular level, using particles identical in size to those in natural teeth and bones—and in a concentration precisely matched to replace your teeth’s daily mineral loss.
- Xylitol (25%): Clinically shown to support a balanced oral microbiome and help maintain a healthy mouth environment.
- pH+ Buffering System: Sodium Bicarbonate and Potassium compounds that instantly balance mouth acidity.

How Carispray Works?
-
1. pH Homeostasis Restoration
The formulation quickly rebalances oral pH from acidic levels (≤5.5) to a more protective, alkaline state (≥7.0), creating the ideal environment for strong, healthy-looking enamel.
-
2.Targeted Oral Balance
Bacteria interact with xylitol thinking it’s sugar, but they cannot process it. This metabolic interaction supports a balanced oral environment, helping the mouth feel cleaner and fresher.
-
3. Biomimetic Remineralization
Precision-sized nano-hydroxyapatite crystals (20–80 nanometers) bond to the tooth surface, helping smooth, strengthen, and enhance the appearance of enamel by supporting its natural mineral balance.
Pharmaceutical-Grade Clinical Validation & Purity Certification
CARISPRAY Adults has undergone rigorous validation through accredited European laboratories following pharmaceutical manufacturing protocols. The formulation received comprehensive analytical verification through ISO-certified testing facilities, establishing clinical-grade purity and biocompatibility standards.
Advanced Clinical Validation Protocol:
- Sterile Microbiological Validation
- Antimicrobial Preservation Efficacy
- Dermatological Biocompatibility
- European Pharmaceutical Compliance
All procedures conducted under cGMP conditions by accredited laboratories, including Meyer d.o.o., Dr Koziej Clinical Research Institute, and Croatian National Institute of Public Health.

FEATURES
FEATURES
Created by implantologist Dr. Martincevic to address enamel health needs in children—now available to everyone.
Science-Driven Innovation
We don't follow trends—we follow research. Every formula is built on clinical evidence and real-world results.
CariSpray maintains optimal pH levels for healthy teeth and gums. No sugar, dyes, or harsh alcohol.
🔬 Teeth Remineralization
Nano-hydroxyapatite penetrates enamel to rebuild tooth structure from within—strengthening teeth at the molecular level with every use.
✨ Restores Natural Whiteness
Nano-hydroxyapatite fills microscopic imperfections in enamel, smoothing the tooth surface to naturally reflect light and reveal your teeth's inherent brightness—without harsh bleaching agents.
🛡️ Protects Tooth Surface
Creates a protective mineral layer that shields enamel from daily acid exposure, wear, and environmental damage—strengthening your teeth's natural defenses with every spray.
🦷 Sensitivity Support
Helps seal exposed dentin tubules that cause sensitivity, providing gentle relief from hot, cold, and sweet triggers while supporting long-term enamel health.
WHAT WE BELIEVE
WHAT WE BELIEVE
We believe you shouldn’t keep getting cavities despite doing everything right. Brushing twice a day shouldn’t be the bare minimum — it should be enough. Modern diets and traditional oral care leave gaps — the hours between brushing, the pH swings from coffee, snacks, and stress, and the damage that happens while you sleep. That’s why we created CariSpray: professional-grade protection that works between the gaps. Real prevention that fits real life — whenever and wherever you need it.

US VS. THEM COMPARISON
Not another harsh mouthwash or temporary fix.
Just dentist-developed pH science that actually supports enamel health.
Hey, I'm Dr. Toni – a dentist, founder of OralAdvance Labs and creator of 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?"
FAQ
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?

What makes our 0.46% nano-hydroxyapatite concentration optimal?
What makes our 0.46% nano-hydroxyapatite concentration optimal?
Research shows that up to 10–14% of enamel hydroxyapatite can be lost during demineralization in typical 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.
