How Fluoride Works
- Fluoride, a natural mineral, protects teeth in three ways.
- It stops demineralization, promotes remineralization, and forms stronger enamel.
Fluoride Discovery
- In 1901, a Colorado dentist observed less decay and unusual staining in some patients.
- This led to 30 years of research, linking the effects to fluoride and establishing community trials.
Fluoridation Prevalence
- About 40% of Canadians live in communities with fluoridated water, contrasting with over 70% in the U.S..
- This isn't because Canadian water is naturally fluoridated at optimal levels.
