From this 2019 study:

Serum concentrations of PFASs and exposure-related behaviors in African American and non-Hispanic white women

https://www.nature.com/articles/s41370-018-0109-y

Flossing with Oral-B Glide was associated with 24.9% (95% CI: 0.2–55.7) higher levels of PFHxS

Exposure to these chemicals and draws attention to coated cardboard prepared food containers and dental floss as modifiable sources. Fast food packaging show that fluorinated chemicals are detected more frequently in paper wrappers than in paperboard containers.

Eating food prepared with nonstick cookware had no significant association with PFAS levels.
