Micro- and Nanoplastics and the Oral Cavity: Implications for Oral and Systemic Health, Dental Practice, and the Environment—A Narrative Review
Summary
This review explores how micro- and nanoplastics are both generated by and introduced through dental practices, including from composite fillings, aligners, and other dental materials. Researchers discuss the potential implications for oral and systemic health, noting that the oral cavity serves as a direct entry point for these particles into the body. The study encourages the dental field to adopt safer, microplastic-free materials and raise awareness among practitioners.
Dentistry is both a source and vector of MNP exposure. Encouraging the use of safer, MNP-free materials, and raising awareness among dental professionals, may support more responsible and health-conscious practices. Further research and alignment with global policy strategies could help guide future innovation and risk mitigation in the dental field.
