According to an article on CBC:
"he panel does acknowledge that excess fluoride intake, which constitutes 10 mg/day after 10 or more years of exposure, can lead to skeletal fluorosis, which is caused by too much accumulation of fluoride in the bones and leads to brittle and deformed bones.
However, "the current maximum acceptable concentration of 1.5 mg/L of fluoride in drinking water is unlikely to cause adverse health effects," reads the report.
The report does caution however, that infants are particularly vulnerable if they ingest powdered infant formula reconstituted with fluoridated water. "The risk of excessive intake of fluoride is higher for infants consuming larger quantities of infant formulas," reads the report."To read the full article go to the CBC site.
