Study Reveals Potential Overdosing of Fluoride Toothpaste for Toddlers

Good oral hygiene is crucial for children’s dental health, but the presence of fluoride in toothpaste has sparked concerns about its safety for infants and toddlers. 

A recent study, published in BDJ Open, explores the doses of fluoride toothpaste parents provide to children up to two years old. The study suggests that many parents might be exceeding the recommended doses, risking dental fluorosis.

“It is crucial to collect more information on how much toothpaste parents are giving their children,” emphasizes the study, given the potential risks associated with fluoride exposure.

Real-Life Dosing by Parents Examined

To test the hypothesis that parents find it challenging to adhere to recommended fluoride toothpaste doses for children up to two years old, researchers conducted a study across five daycare centers in Germany. Parents were asked to use commercially available fluoride toothpaste for children and dose them as they typically did at home.

“The study aimed to understand real-life dosages and their alignment with recommended guidelines,” notes the research team.

Parents Overdosing Fluoride Toothpaste

The results indicate a significant discrepancy between recommended doses and actual amounts provided by parents. On average, parents dosed their children with 5.6 to 8.2 times more fluoride than the optimal recommendation of one grain’s rice worth of toothpaste. 

More than 60% of parents were unaware of fluoride health warnings, and nearly 15% used fluoride tablets in addition to toothpaste.

“These findings suggest that children may be receiving overdoses of fluoride, even surpassing upper limits to avoid dental fluorosis,” the study concludes.

Implications and Recommendations: Exploring Alternatives

The study points out potential reasons for large dose sizes, including misleading toothpaste commercials and the palatable flavor of toothpaste, leading children to ingest more. 

In response to these concerns, researchers recommend considering fluoride-free toothpaste varieties containing alternatives like calcium sodium phosphosilicate or hydroxyapatite.

“Encouraging parents to replace fluoride toothpaste with efficient and safe alternatives can promote oral care in young children and keep them safe from fluorosis,” the researchers suggest.

The study underscores the need for further research to conduct a comprehensive risk assessment, considering other sources of fluoride exposure and potential neurotoxicity outcomes. 

Additionally, socioeconomic factors should be taken into account to better understand the broader implications of dental care practices among parents.

“Addressing these concerns can contribute to creating safer oral care practices for toddlers and infants,” emphasizes the study’s recommendations.
