Should you worry about the plastic in your floss and toothbrush?

It is almost impossible to avoid microplastics altogether. These tiny plastic particles are regularly ingested, inhaled and absorbed from the environment and have been found in our hearts, brains and other organs.

Plastic bottles, cutting boards and food containers are well-known culprits, but researchers are increasingly finding that dental products – such as toothbrushes and floss – can shed microplastics too.
