FLUORIDE IN DRINKING WATER – EVERYTHING YOU NEED TO KNOW ABOUT IT
In toothpaste, fluoride is a matter of course. In order to protect the teeth from tooth decay, most dental care products in the world are enriched with the trace element.
WHAT IS FLUORIDE?
Fluorides are the salts of hydrofluoric acid. Fluoride is naturally found in soil and water as a trace element. Fluorides are also present in the human body, about 5 grams of fluorides are found in a human organism with 70 kilograms of body weight. Most of this amount is stored in the bones and teeth.
WHAT IS THE SIGNIFICANCE OF FLUORIDE FOR THE HUMAN BODY?
The human organism doesn’t require this trace element. However, scientists have shown that fluoride is beneficial in small amounts to prevent tooth damage. It repairs small damage to the enamel after acidic meals and inhibits the growth of bacteria that form acid and thus harm teeth. The longer-term intake of too much fluoride, on the other hand, can cause damage to the kidneys, teeth and bone substance, because the substance is toxic. Infants are particularly sensitive, high absorption of the trace element can lead to damage to tooth enamel. Therefore, children should not use fluoride-containing toothpaste until they can safely spit out and rinse.
HOW MUCH FLUORIDE IS IN DRINKING WATER?
Tap water generally contains less than 0.5 milligrams of fluoride. The Federal Institute for Risk Assessment (BfR) states that 90% of drinking water contains less than 0.3 milligrams of fluoride.
- 3.1 milligrams per day for women
- 3.8 milligrams for men.
These values cannot be reached naturally by the fluoride in drinking water. Depending on the individual lifestyle, consumers absorb between 0.4 and 1.5 milligrams of fluoride through food and drinking water. Experts therefore recommend the use of fluoride-containing toothpastes and mouthwashes as well as fluoridated table salt, which is usually enriched with 250 milligrams of fluoride per kilogram to improve dental health.
