Functions and dietary sources of fluorine

Fluoride is an essential mineral for oral health and the prevention of tooth decay. Although it is not considered an essential nutrient in the traditional sense, as it is not required for basic bodily functions, it plays a crucial role in tooth strength and protection against decay.

In this session, we will explore the functions and dietary sources of fluoride, and how its inclusion in the diet can benefit oral health.

Key Functions of Fluoride

Fluoride has a specific and vital function in the human body:

Fluoride's primary function is to strengthen tooth enamel and prevent tooth decay. When fluoride is incorporated into tooth enamel, it makes it more resistant to acids and bacteria that cause tooth decay. This helps keep teeth healthy and reduces the risk of tooth decay.

Fluoride needs

Fluoride needs vary by age and geographic location. In many places, fluoride is added to drinking water as a method of preventing tooth decay. This is known as water fluoridation and has proven to be an effective strategy for improving oral health.

Daily fluoride requirements are:

• Infants 0 to 6 months: Approximately 0.01 mg per day.

• Children from 7 to 13 years old: About 0.05 mg per day.

• Adolescents and adults: Between 0.05 and 0.05 mg per day.

Most people can meet their fluoride needs through drinking water, food and, in some cases, supplements. However, excess fluoride can lead to dental fluorosis, a condition that causes staining of the teeth.

Food Sources of Fluoride

Fluoride is found in a variety of food and liquid sources. Some of the main sources of fluoride are:

• Drinking Water: Dr inking water is the main source of fluoride for most people. Water fluoridation is a common practice in many communities to improve the oral health of the population.

• Tea: Tea, especially black and green tea, contains significant amounts of fluoride. Regular consumption of tea can contribute to fluoride intake.

• Fish and Seafood: Some types of fish and shellfish, such as snapper and sea bass, contain fluoride due to absorption of the mineral in ocean water.

• Animal Products: Meat and milk may also contain trace amounts of fluoride, as animals can accumulate fluoride in their tissues through their diet and the water they consume.

Beware of Dental Fluorosis

While fluoride is essential for oral health, it is important not to exceed recommended doses. Excess fluoride during childhood tooth formation can lead to dental fluorosis, which manifests as white or brown stains on permanent teeth.

To avoid dental fluorosis, follow these recommendations:

• Make sure your drinking water does not have excess fluoride. If you live in an area where the water is fluoridated, you do not need additional fluoride supplements.

• Teach children to use the proper amount of fluoride toothpaste, especially if they are prone to swallowing it.

• If you have concerns about dental fluorosis or the amount of fluoride you are consuming, consult a dentist or oral health professional.
