Fluoride
Guide
Not all fluoride is the same. Concentration determines whether you're maintaining healthy teeth or actively reversing decay.

Your enamel is made of hydroxyapatite — a calcium phosphate mineral. When oral pH drops below 5.5, acid dissolves this mineral in a process called demineralization. Fluoride works by integrating into the enamel structure and forming fluorapatite, a harder, more acid-resistant mineral that doesn't dissolve until pH drops below 4.5.
This isn't just protection — it's active repair. When fluoride is present alongside calcium and phosphate (as in saliva), it accelerates the redeposition of minerals into micro-defects in the enamel surface. Combined with nano-hydroxyapatite, this process is significantly enhanced.

The standard OTC fluoride level, paired with nano-hydroxyapatite to help repair micro-defects and harden enamel — no prescription needed.Prescription fluoride
For patients with active decay or extremely high cavity risk.Frequently asked
How does fluoride prevent cavities?
Fluoride ions replace hydroxyl groups in hydroxyapatite to form fluorapatite — a significantly harder mineral that resists acid dissolution at lower pH levels (down to ~4.5 vs 5.5 for regular enamel).
Why does concentration matter?
Higher concentrations deliver more fluoride ions per application, leading to deeper and faster mineral deposition. Standard OTC concentrations maintain healthy enamel; therapeutic concentrations actively reverse early decay.
Is fluoride safe?
Yes, at therapeutic concentrations. Dental fluorosis only occurs during tooth development in childhood from excessive ingestion — not from topical adult use. The OneOral formulas are designed for topical adult application.
Is Gel 1100's fluoride stronger than store toothpaste?
No — 1,100 ppm sodium fluoride is the standard OTC anticaries level, the same as a good drugstore toothpaste. What sets Gel 1100 apart isn't the fluoride strength; it's the medical-grade nano-hydroxyapatite and 25% xylitol paired with it. Only prescription-strength fluoride (about 5,000 ppm) requires a dentist.
Get therapeutic-strength fluoride
OneOral Gel 1100 pairs standard 1,100 ppm sodium fluoride with nano-hydroxyapatite for a more complete daily remineralization formula.
