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.
