Fluoride 101

By: Dr. Sharanya Srinivasa DMD

What is fluoride and why is it used in dental care? Fluoride is a mineral that occurs naturally in many foods, as well as city water in certain places. Some natural sources of fluoride are brewed tea, canned fish, cooked kale, spinach, apples, and skim milk.

A lack of fluoride makes you more prone to cavities. Fluoride helps prevent tooth decay by making your tooth enamel more resistant to acid attacks from plaque and acidic foods.The dentist also gives fluoride treatments during the routine cleanings, predominantly for children. This help keeps cavities from forming. Adults can also benefit from fluoride.

Research has shown that communities that have fluoride in the tap water have less cavities than communities that do not fluoridate their water supply.  The amount of fluoride in water is very low and does not cause health related side effects but is needed to maintain oral health.

It is recommended that you have a fluoride treatment once every 6 months. Especially is you are prone to cavities.
