Bioactive Toothpaste – The Next Generation?

An innovative active ingredient (bioactive glass) forms a protective mineral layer after brushing, which strengthens teeth, reduces sensitivity, and has a residual effect for up to 12 hours.

The article shows why this technology (e.g., in BioMin or Snow Pearl) has long been established in Europe – and is now conquering the US market.

Bioactive Glass in Toothpaste (BioMin / Snow Pearl)

What is bioactive glass?

Bioactive glass is a special active ingredient in toothpastes (e.g., BioMin or Snow Pearl Plus Gel) that reacts with saliva in the mouth to form a protective mineral layer on the teeth.

This layer:

• strengthens tooth enamel

• protects against acid attacks

• helps with sensitive teeth

Effect on tooth sensitivity

Sensitive teeth occur when:

• the enamel is eroded

• dentinal tubules (tubuli) are exposed

👉 Bioactive glass works by:

• sealing these tubules

• thereby blocking the stimulus to the nerve

✔️ Advantage:
The effect is longer-lasting and more stable than with many other toothpastes.

Special feature of BioMin (vs. older technologies like NovaMin)

BioMin contains fluoride directly incorporated into the glass (BioMin F):

👉 This slowly releases:

• Fluoride

• Calcium

• Phosphate

⏳ Effect:

• continuous release for 8–12 hours after brushing

Why is this important?

• It forms fluorapatite (not just hydroxylapatite)

• Fluorapatite is:

  • more acid-resistant

  • more stable (dissolves only at a lower pH)

👉 Result:

• better long-term protection against cavities & erosion

Further advantages

• very small particles → penetrate tubules better

• low abrasion (gentle on tooth structure)

• Combination of:

  • chemical protection

  • mechanical protection

🇺🇸 Why was this not available in the US for a long time?

• stricter regulation (toothpaste = "drug", not cosmetic)

• high costs for studies

• therefore no FDA approval for a long time

👉 Already available in Europe (e.g., Snow Pearl)

New: FDA approval

• BioMin received FDA Clearance

• first fluoride-containing bioactive glass product in the USA

• initially prescription-only

Conclusion (simply explained)

👉 Bioactive glass is:

• a modern remineralization technology

• particularly effective for:

  • sensitivity

  • erosion

  • initial caries

👉 Difference to classic fluoride:

• not just short-term protection

• but long-lasting active ingredient release + layer formation

• Snow Pearl Plus Gel also uses this technology

• good alternative to:

  • classic sensitive toothpastes

  • especially for demanding patients
