Dental floss is a seemingly innocuous part of our oral hygiene routine, promoted for its ability to remove plaque and prevent gum disease. However, a closer look reveals a potential health concern – fluoride and per- and polyfluoroalkyl substances (PFAS) in certain dental floss products. This article will delve into the health impacts and dangers associated with fluoride and PFAS in dental floss, supported by scientific sources and expert opinions. Non-toxic products are something I have been passionate about for years, which is why my ebook contains a section on endocrine disruptors. So, what is the best dental floss for those wanting to avoid these ingredients? Keep reading to find out. 


Understanding Fluoride and PFAS in Dental Floss

Fluoride, often used in dental care products for its cavity-fighting properties, and PFAS, known for its water and grease-resistant properties, have raised concerns in recent years. Dental floss with added fluoride and PFAS is marketed as offering an extra layer of protection against tooth decay and enhancing floss performance. However, the potential health risks associated with this practice are significant.


Health Impacts of Fluoride and PFAS in Dental Floss

  1. Fluorosis Risk: Dental fluorosis, a condition characterized by discoloration and pitting of tooth enamel, is a well-documented risk associated with excessive fluoride exposure. Dental floss with added fluoride contributes to the overall fluoride intake, increasing the likelihood of fluorosis, especially in children.

2. Potential for Systemic Absorption: The oral mucosa can absorb substances, raising concerns about the systemic absorption of fluoride and PFAS from dental floss. Studies indicate that prolonged exposure may lead to elevated blood fluoride and PFAS levels, posing risks to various organs.

3. Endocrine Disruption: Fluoride has been linked to endocrine-disrupting effects, affecting hormonal balance in the body. PFAS compounds may also disrupt endocrine function, compounding the potential risks.

4. Neurological Concerns: Some studies suggest a potential connection between elevated fluoride levels and adverse effects on neurological development. Prenatal exposure and early childhood intake may pose risks to cognitive function. PFAS exposure has also been associated with neurological impacts.
