Things worth knowing about "Fluoride prophylaxis"
Fluoride prophylaxis refers to measures that use fluoride compounds to prevent tooth decay. It is recommended for children and adults alike.
What is Fluoride Prophylaxis?
Fluoride prophylaxis describes all targeted measures in which fluoride compounds are used to prevent or slow down dental caries (tooth decay). Fluorides are compounds of the chemical element fluorine and occur naturally in small amounts in water, soil, and many foods. In dentistry, they have been recognised for decades as one of the most effective tools for caries prevention and are recommended by the World Health Organization (WHO) as well as national dental associations worldwide.
How Does Fluoride Work?
Fluoride protects teeth through several mechanisms:
- Remineralisation: Fluoride promotes the reintegration of minerals (primarily calcium and phosphate) into damaged tooth enamel, making it more resistant to acid attacks.
- Inhibition of bacteria: Fluoride inhibits the metabolism of caries-causing bacteria (especially Streptococcus mutans), reducing acid production in the oral cavity.
- Formation of fluorapatite: Fluoride is incorporated into tooth enamel and forms fluorapatite, a compound more stable than naturally occurring hydroxyapatite. Fluorapatite is less soluble and more resistant to acid dissolution.
Forms of Fluoride Prophylaxis
Systemic Fluoride Application
In systemic application, fluoride is absorbed by the body and acts from within during tooth development. Common forms include:
- Fluoride tablets: Recommended primarily for young children and school-age children whose teeth are still developing. These supplements are often combined with vitamin D.
- Fluoridated table salt: In many countries, including Germany, table salt is commonly enriched with fluoride. This is a simple and cost-effective population-level prevention measure.
- Fluoridated drinking water: In some countries (e.g., the United States), drinking water is deliberately fluoridated. This practice is not common in Germany.
Topical Fluoride Application
In topical application, fluoride is applied directly to the tooth surface. This is the currently preferred and most evidence-based form of fluoride prophylaxis:
- Fluoride toothpaste: The daily use of fluoride-containing toothpaste is the single most important and most effective topical fluoride measure for all age groups.
- Fluoride gels and varnishes: Applied by dental professionals, these products contain higher fluoride concentrations and are particularly suitable for high-risk patients.
- Fluoride rinses: Mouthwashes containing fluoride may be used as an additional measure, especially for individuals with elevated caries risk.
Recommendations by Age Group
Fluoride dosage recommendations vary according to age:
- Infants (from first tooth eruption): Brush twice daily with a rice-grain-sized amount of children's toothpaste (500 ppm fluoride).
- Children aged 2–6 years: A pea-sized amount of children's toothpaste (500–1000 ppm fluoride), twice daily.
- Children aged 6 and above and adults: Toothpaste containing 1000–1500 ppm fluoride, twice daily.
Safety and Risks
When used correctly, fluoride is considered safe. However, excessive fluoride intake can lead to dental fluorosis – white spots or discolouration of the tooth enamel, which mainly occur when young children swallow excessive amounts of fluoride toothpaste. Severe systemic toxicity (skeletal fluorosis) is not expected at the levels used in prophylactic settings in most countries. Parents should nonetheless ensure that children do not swallow fluoride toothpaste.
Public Health Significance
Fluoride prophylaxis has contributed significantly to the marked reduction in caries prevalence observed in many countries over recent decades. Regular dental check-ups, good oral hygiene practices, and a balanced diet complement the protective effects of fluoride prophylaxis.
