The Microplastic Footprint of Orthodontics

Summary

This review pulls together existing research showing that orthodontic devices like clear aligners, retainers, and tooth-colored fillings can shed tiny plastic particles—known as microplastics and nanoplastics—into your mouth over time. While scientists are still studying exactly how these particles affect our health, the paper suggests practical steps dentists can take to reduce this plastic exposure, which matters since millions of people wear these devices for months or years at a time.
