Fluoride explained
What fluoride does, where it comes from, and how to use fluoride toothpaste effectively.
What fluoride does
- Helps prevent tooth decay by strengthening enamel and supporting remineralization.
- Works best with consistent, low-level exposure (e.g., fluoride toothpaste used properly).
Where fluoride comes from
- Fluoride toothpaste (most common).
- Fluoridated community water (where available).
- Professional treatments or prescription products (dentist-directed).
Using fluoride toothpaste well
- Brush for about 2 minutes.
- After brushing, spit out excess toothpaste and avoid rinsing immediately.
If you’re considering high-strength fluoride products or supplements, consult a dentist—needs vary by age, risk, and local water fluoride levels.
