Fluoride is added to London’s drinking water to bring the levels to 0.7 mg / litre (mg/L) or parts per million (ppm). This is the level recommended by Health Canada to prevent tooth decay and minimize the risk of dental fluorosis. The level of fluoride in the drinking water is closely monitored by the City of London and the Middlesex-London Health Unit.
At the levels used to fluoridate London's drinking water, the only recognized risk is a condition called dental fluorosis. This is a condition where spots form on the teeth. In its mild and very mild form, the spots are white and only noticeable by a dental professional. In its moderate or severe form, the spots can be brown and more noticeable. Fluorosis comes from fluoride exposure when the teeth are forming and is mostly a problem in the permanent front teeth which form at around 22 to 26 months of age. A study by Health Canada found very little fluorosis in Canadian children. Mild fluorosis was found in 4% of children and very mild fluorosis was found in 12% of children; no severe fluorosis was noted and hardly any moderate fluorosis was noted in the study.
Numerous reviews, including a recent review by Health Canada, have not identified any other health risk from the levels of fluoride added to London’s drinking water. Specifically, the reviews did not identify a risk for fractures, thyroid problems, cancer or effects on IQ.
The risk of fluorosis increases when young children swallow fluoridated toothpaste. To decrease this risk, the Health Unit recommends that children less than 3 years of age not use fluoridated toothpaste, unless suggested by their dentist. For children 3 years of age and older, only a very small pea-sized amount of fluoridated toothpaste should be used and children should be encouraged not to swallow the toothpaste. Children 3 to 6 years of age should be helped by an adult with brushing their teeth.
Yes, infant formula from concentrate or powder can be mixed with London’s water. According to Health Canada, infant formula prepared with water fluoridated at the optimal level of 0.7 mg/L maximizes the protective role of fluoride during the development of the permanent teeth while minimizing the risk of dental fluorosis.
