These studies suggest that fluoride toothpastes, especially those with higher fluoride concentrations and used frequently or under supervision, effectively prevent dental caries in children, though there is a risk of fluorosis with higher concentrations.

Fluoride Toothpaste Prescription: An Overview
Effectiveness of Fluoride Toothpaste in Preventing Dental Caries
Fluoride toothpaste has been a cornerstone in the prevention of dental caries for over three decades. Research consistently supports its efficacy in reducing caries in children and adolescents. A comprehensive meta-analysis involving 42,300 children demonstrated that fluoride toothpaste reduces caries increment by 24% compared to non-fluoride toothpaste, with the effect being more pronounced in populations with higher baseline caries levels and higher fluoride concentrations. Another study confirmed that fluoride toothpaste significantly reduces caries in both primary and permanent dentition, with higher fluoride concentrations (1000 ppm and above) being more effective.
Fluoride Concentration and Caries Prevention
The concentration of fluoride in toothpaste plays a critical role in its effectiveness. Studies have shown a dose-response relationship, where higher fluoride concentrations (up to 2800 ppm) provide greater caries prevention. For instance, toothpastes with 2400-2800 ppm fluoride showed a 36% reduction in caries compared to placebo, whereas concentrations below 550 ppm did not show a significant effect . This indicates that for high caries risk individuals, higher fluoride concentrations may be necessary.
Prescription-Strength Fluoride Toothpastes
Prescription-strength fluoride toothpastes, containing 2800 ppm and 5000 ppm fluoride, are available for individuals at high risk of caries, including adolescents, adults, and the elderly. These high fluoride toothpastes have been shown to provide additional protection against caries, particularly in high-risk groups. However, the use of such high concentrations should be balanced with the risk of dental fluorosis, especially in young children.
Safety and Adverse Effects
While fluoride toothpaste is generally safe when used as directed, concerns about dental fluorosis (enamel defects) exist, particularly with higher fluoride concentrations. The European Academy of Paediatric Dentistry (EAPD) recommends that parents supervise their children's toothbrushing and use age-appropriate amounts of toothpaste to minimize the risk of fluorosis. Adverse effects such as soft tissue damage and tooth staining are minimal and were reported in only a minority of studies.
Guidelines and Recommendations
The EAPD strongly endorses the daily use of fluoride toothpaste as part of a comprehensive caries prevention program. They recommend that preventive programs be tailored to individual needs and re-evaluated regularly. For preschool children, standard fluoride toothpastes (1000-1500 ppm) are effective in reducing caries and should be recommended.
Conclusion
Fluoride toothpaste remains a highly effective measure for preventing dental caries in children and adolescents. Higher fluoride concentrations provide greater protection, particularly for high-risk individuals, but must be used judiciously to avoid adverse effects. Regular use of fluoride toothpaste, combined with good oral hygiene practices, is essential for maintaining dental health.
