Detection and Identification of Various Microplastics in Different Orthodontic Adhesives
Researchers found microplastics in four different brands of orthodontic adhesives used by dentists to attach braces. The microplastics were identified as fibers, fragments, and pellets containing various plastic polymers. While the amount is small compared to other plastic pollution sources, this study shows that dental materials can introduce microplastic particles into patients' mouths and eventually into the environment.
Micro and nanoplastics in dentistry: emerging sources, health implications, and mitigation pathways: a narrative review.
This review of existing research found that common dental materials and oral care products like toothbrushes, toothpaste, and dental fillings can release tiny plastic particles called microplastics into your mouth. Lab studies suggest these particles might cause inflammation and cell damage when they build up in mouth tissues, though scientists haven't yet proven they cause actual health problems in people. The good news is that dentists and patients can reduce exposure by using better suction systems during procedures and choosing oral care products that shed fewer plastic particles.
Microplastic Release from Dental Materials: Environmental and Biological Implications
This review examines how dental materials—composites, adhesives, denture bases, and orthodontic appliances—degrade under mechanical, thermal, enzymatic, and chemical stressors to release microplastics, contributing to both direct patient exposure and environmental contamination.
Patterns and risks of microplastic release during primary oral care in Chinese residents
Researchers studied microplastic release from toothpaste and toothbrushes commonly used in China and found that both products shed significant numbers of plastic particles during normal use. While the levels from any single brushing session were considered low-risk, the cumulative annual release was substantial, reaching hundreds of thousands of particles per person per year from toothbrushes alone. The study highlights oral care products as an overlooked daily source of microplastic entering both people and the environment.
The unseen perils of oral-care products generated micro/nanoplastics on human health
This review reveals that everyday oral care products like toothpaste, toothbrushes, and dental materials release micro and nanoplastics into the mouth through normal use. These tiny particles are generated by mechanical friction, pH changes, and temperature shifts during brushing and dental procedures. Since the mouth is a direct entry point to the digestive system, this overlooked source of microplastic exposure could have significant implications for human health.
Negative Impact of Dental Wastewater on the Environment and Human Health: A Scoping Review
This scoping review analyzed evidence on dental wastewater as a source of environmental and health risks, finding that it contains physical, chemical, and microbiological hazards — including plastic particles from dental materials — that are inadequately managed in most healthcare settings.
Impact of the dental sector on the environmental pollution: an overview
This review summarises the environmental impact of the dental sector, focusing on mercury from amalgam, microplastic release from resins and disposable materials, and high energy and water consumption. It evaluates green dentistry concepts and sustainable practice alternatives.
Microplastics and nanoplastics in healthcare: environmental persistence, health implications, and professional awareness
This review examines how micro- and nanoplastics have infiltrated ecosystems, food, water, and even human tissues, with particular focus on their relevance to healthcare settings — especially dentistry and orthodontics — where extensive plastic use generates microplastic debris from single-use items and clear aligners.
