A mineral that strengthens tooth enamel and prevents cavities. Found in toothpaste, tap water (in some areas), and professional varnish.
In detail
Fluoride works by promoting remineralisation of early decay and making enamel more resistant to acid. Professional fluoride varnish applied every 6 months provides strong protection. Standard adult toothpaste has 1,450 ppm fluoride.
