If you’ve ever winced from a sharp sting when sipping cold water or biting into ice cream, you know how uncomfortable sensitive teeth can be. Millions of people suffer from this problem, and while many toothpastes promise relief, they don’t always deliver lasting results.
That’s where bioactive glass toothpaste comes in. Once used in medicine for bone healing, this special ingredient (scientifically called calcium sodium phosphosilicate and often marketed as NovaMin®) is now making waves in dental care. Dentists love it because it doesn’t just mask sensitivity—it actually helps repair and protect your teeth.
Let’s break it down in simple terms and explore everything you need to know about this breakthrough ingredient.
What Is Bioactive Glass Toothpaste?
- Definition: Bioactive glass is a material made of calcium, sodium, silica, and phosphorus.
- How it works: When bioactive glass in toothpaste contacts saliva, it releases calcium and phosphate ions that form a protective mineral layer (similar to your natural enamel) on exposed dentin.
- Why it matters: Instead of just numbing nerves like older toothpastes (e.g., potassium nitrate), it actually repairs and blocks the open channels (dentinal tubules) that cause sensitivity.
How Bioactive Glass Toothpaste Helps with Sensitivity
- Seals exposed dentin → Creates a natural shield against hot, cold, and sweet triggers.
- Rebuilds enamel → Provides minerals your teeth can absorb.
- Long-lasting relief → The protective layer is durable, unlike temporary numbing.
- Supports gumline health → Especially helpful where gums have receded and roots are exposed.
Bioactive Glass vs Traditional Sensitivity Toothpastes
- Potassium nitrate: Numbs the nerve but doesn’t fix the cause.
- Stannous fluoride: Strengthens enamel but can stain teeth in some cases.
- Bioactive glass toothpaste: Offers both relief and natural repair, making it a favorite among dentists.
Who Should Use Bioactive Glass Toothpaste?
- People with tooth sensitivity from hot, cold, sweet, or brushing.
- Anyone with gum recession or exposed roots.
- Those with post-whitening sensitivity.
- Patients after scaling and polishing who feel temporary discomfort.
- Bruxism sufferers (teeth grinding) who wear enamel down.
Benefits Beyond Sensitivity Relief
- Cavity prevention: Extra calcium and phosphate strengthen teeth.
- Enamel remineralization: Rebuilds weak spots before they turn into cavities.
- Whitening support: Reduces side effects of bleaching treatments.
- Safe for long-term use: Unlike some medicated products, it’s gentle and biocompatible.
Are There Any Side Effects?
- Generally safe and well-tolerated.
- Some people may experience mild temporary grittiness (due to glass particles).
- Always check labels if you have silica allergies (rare).
- Safe for kids if labeled as children’s toothpaste.
How to Use Bioactive Glass Toothpaste
- Brush twice daily like normal toothpaste.
- Don’t rinse immediately after brushing—let the minerals stay longer.
- Combine with fluoride toothpaste if recommended by your dentist (some brands include both).
- Be patient—relief often starts within a few days but full benefits may take 2–4 weeks.

It can help remineralize very early-stage lesions, but it won’t heal full cavities. - Does it taste different?
No, most formulas taste like regular toothpaste (minty or mild). - Is it available everywhere?
Not always—it may be limited to certain brands or regions. - Can it stop sensitivity from braces or retainers?
