How does water fluoridation compare to other public health measures?
To protect public health we:
- add folic acid to cereal products to prevent birth defects;
- add iodide to salt to prevent goiter;
- add chlorine to water to disinfect it;
- add vitamin D to milk to build stronger bones.
Fluoridation is similar to other ways we protect public health.
Some controversy surrounds fluoridation. Opponents question the benefits and safety of ingesting fluoride.
