Fluoride in drinking water has been proven to help protect teeth from cavities. And the amount of fluoride in drinking water is strictly controlled and is considered safe. However, there have been claims of risks with excess fluoride intake.
A new study suggests that exposure to excess fluoride in utero may lower the fetus’ IQ. Also, extreme doses may cause:
– Tooth discolouration
– Painful damage to bones
These are rare problems that should not prevent you from drinking fluoridated water. Excess fluoride is the problem. Talk to your dentist about concerns regarding fluoride, especially if you are pregnant.
