What about London?
The City of London draws its water supply from Lakes Huron and Erie, which have relatively low natural fluoride levels. Fluoride is added to drinking water to help people have the best possible dental health.2
Drinking fluoridated water reduces cavities by about 25% in children and adults.3 The small amount of fluoride in saliva bathes the teeth, stopping or even reversing the damaging effects that acids found in the food and beverages we consume can have on tooth enamel.
Drinking water that has been fluoridated to the optimal level for dental health is not associated with adverse health effects. Research into the health effects of water fluoridation has been going on for more than 70 years. There are more than 90 well-respected national and international organizations that support water fluoridation, including:
- World Health Organization
- Pan American Health Organization
- FDI World Dental Federation
- Centers for Disease Control and Prevention, USA
- Health Canada
- Canadian Medical Association
- Canadian Pediatric Society
- Canadian Dental Association
- American Dental Association
