- Fluoride is a form of the element fluorine, occurring naturally in water and some foods.
- Fluoride strengthens tooth enamel by aiding remineralization, making teeth more resistant to decay.
- High fluoride levels can cause fluorosis, but water fluoridation in Australia is kept at safe levels (0.6-1.1 mg/L).
- Studies show water fluoridation reduces cavities by over a third and lowers children's dental hospital admissions.
- Most Australians have fluoridated tap water, but some areas, especially in Queensland, do not.
- Standard water filters usually don’t remove fluoride, but ion exchange filters can.
- Without fluoridated water, good oral hygiene (brushing with fluoride toothpaste, reducing sugar intake) is essential.
- Stannous fluoride toothpaste offers additional antibacterial benefits.
- Regular dental visits and fluoride varnishes help prevent decay, but access remains unequal for disadvantaged communities.
- Public health education on oral hygiene is crucial in areas without fluoridated water.
