Colgate Duraphat 2800ppm fluoride toothpaste is a prescription-only high-fluoride toothpaste.
There is a clinically-proven dose-dependent relationship between the level of fluoride in a daily toothpaste and the degree of clinical anti-caries efficacy.2
Sodium fluoride applied topically reduces caries by inhibiting demineralisation and promoting remineralisation of the tooth surface. It is effective on both enamel and exposed dentine.
