What is fluoride and why is it controversial?
A. Fluoride is a substance that strengthens the enamel (outer coating) of teeth. It can be administered in a number of ways. In many communities fluoride is added to the drinking water so that every time you have a glass of water you get a small amount of fluoride internally. Most toothpastes contain fluoride and there are over-the-counter mouthrinses that contain fluoride. In addition many dentists will give their patients fluoride treatments as part of a standard recall appointment. In communities where the water supply is not fluoridated many pediatricians will prescribe fluoride supplements to their young patients. Fluoride is controversial because like many substances it can be harmful in large doses. If a child swallows a significant amount of toothpaste or a fluoride mouthrinse it can make them sick and discolor their teeth. Also, many extremists believe that water fluoridation by the government is an unethical way to mass medicate the population against its will.
