Dental caries are caused when the caries causing bacteria come in contact with carbohydrates such as sugar on the tooth surface over the time. One of the most effective ways to prevent dental caries is by promoting re-mineralization and slowing down of demineralization. To achieve this fluoride has become an indispensable ingredient.

Fluoride is a natural mineral that strengthens teeth enamel and prevents tooth decay. Several experts opine that using fluoride is the best way to prevent caries. In children younger than 6 years, fluoride is incorporated into the enamel of the permanent teeth making the teeth resistant to the attack of bacteria and acids present in few food & beverages consumed by them.

Sources of Fluoride

Use of fluoride from multiple sources can stop damage of teeth. Fluoride is present in small amounts in water and it can be found in foods such as fish, eggs and meat. Manufactured source of fluoride include toothpaste, mouth rinse, professionally applied products and supplements. Major source of fluoride include:

Groundwater: Naturally occurring groundwater contains fluoride, but the concentration varies. Some areas may contain dangerously high levels of fluoride; this may lead to serious health problems.

Fluoride supplements: Fluoride supplements are available as drops or tablets and are generally recommended for children over 6 months of age who have high risk of developing cavities and live in areas with non-fluoridated water supplies.

Dental care products: Fluoride is added to a number of dental care products such as mouthwash and toothpaste.

Certain foods: A few food articles may be processed using fluoridated water or may absorb fluoride from the soil. Tea leaves, especially old ones may contain fluoride in higher amount than other foods.

Like many other nutrients, fluoride is safe and effective when used and consumed inappropriate amounts. It can prevent caries but ingesting it in large amounts may lead to serious health problems.
