Prevention
Fluoride
Fluoride is a naturally occurring mineral that strengthens tooth enamel and helps reverse early stages of tooth decay.
Fluoride works by promoting remineralisation — the deposition of calcium and phosphate back into weakened enamel — and by making enamel more resistant to acid attack.
Sources of fluoride
- Fluoridated tap water (where available)
- Fluoride toothpaste (1,000–1,500 ppm for adults) — see our pick of expert-recommended toothpastes
- Professional fluoride varnish applied by a dentist
- Fluoride mouth rinses such as ACT Fluoride Rinse
