Fluoride is a mineral that occurs naturally in many foods and in water. Some natural sources of fluoride are brewed tea, canned fish, cooked kale and spinach, apples, and skim milk. Some city water contains fluoride, so by drinking tap water you will acquire fluoride. If drinking water does not have fluoride, supplements are available.

The lack of exposure to fluoride places individuals of any age at risk for dental decay. Fluoride is important to dental health because it helps prevent tooth decay by making your tooth enamel more resistant to acid attacks from plaque bacteria in your mouth.

Studies have shown that children who consumed fluoridated water from birth had less dental decay. Fluoride can reverse early decay and help prevent osteoporosis, a disease that causes degenerative bone loss. Talk to your dentist or dental hygienist about whether you're getting the daily amount of fluoride you need.
