Fluoride is in toothpaste because it is known that applying small amounts of fluoride to the tooth enamel helps to reverse the effects of acid-producing bacteria and acid containing foods, re-mineralize the tooth surface and create a stronger, more decay-resistant tooth.

In many toothpastes, fluoride is the only "active ingredient" listed, which means that it is the only ingredient known to have a defined therapeutic benefit for the user.

For those who prefer non-fluoride containing toothpastes, they are available in health food and vitamin supplement nutrition stores.

Fluoride is added to toothpaste, water and other oral care products because it is believed to aid in the prevention of cavities.

The idea that fluoride improves dental health was generated in the 1940's. More recently, several studies have produced contradicting evidence. Fluoride is a harmful substance which is linked to cancer and (ironically) tooth enamel degeneration when ingested too often.

There are several non-fluoride toothpaste varieties on the market.
