The document discusses fluorine, including foods that contain it like tea, soda, fish, butter, and water. Fluorine is needed to strengthen teeth and bones. Without enough fluorine, teeth can become weak, bones can become fragile, growth can be stunted, and muscles won't develop properly. Too much fluorine can cause spots on teeth. Fluorine can dissolve into bones and sometimes acts as a substitute for hydrogen in compounds.
