Fluoride![]() |
||||
Drinking water that naturally contains 2ppm to 7ppm of fluoride can cause mottling, pitting, and dulling of the teeth.
Very high intakes of fluoride can produce arthritis-like symptoms.
The most severe symptoms of excessive fluoride intake include bone and tooth malformations.
There is no Daily Value or Recommended Dietary Allowance (RDA) for fluoride, but the estimated daily safe and adequate range is 1.5mg. to 4mg. for adults.
The average daily intake of fluoride is 0.2mg. to 3.4mg.
Dental cavities are more common when fluoride intake is low.
