In Buffalo, New York, citizens are suing the city because they believe there is not enough fluoride in the water, affecting their children's dental health. The city may have corrected the fluoride levels in response.

How does fluoride affect teeth?

Fluoride strengthens teeth by forming stronger bonds within the mineralization structure of teeth, making them more resistant to acid erosion from bacteria, which helps prevent cavities.

What are the potential health risks associated with excessive fluoride intake?

High levels of fluoride can disrupt thyroid hormone function and have been hypothesized to be neurotoxic, potentially damaging neurons, although this is still highly debated.

How can one determine the fluoride concentration in their drinking water?
