The Academy of General Dentistry (AGD) recently published an article highlighting emerging research examining microplastics and dental materials and the potential relevance to oral and overall health care. Published in the March/April issue of General Dentistry, “What Every Dentist Need to Know About Microplastics and Dental Materials” delves into the sources of microplastics in foods and dental products and assesses the potential health risks to

Microplastics that are tiny, nondegradable plastic particles found widely in air, water and consumer products are an increasing focus of global scientific study. Dental materials and oral health products are among many everyday sources being evaluated for environmental impact and possible health implications. The production of nondegradable microplastics is a growing global concern due to potential long-term health effects on humans. The authors note that because the dental industry has relied heavily on plastics for contamination prevention, protective equipment, restorative materials and hygiene products, it is important that dentists understand the implications of microplastics exposure and that manufacturers develop alternatives for health care.

“The widespread production of microplastics has become a global concern due to the continuous exposure to humans through ingestion and inhalation from the environment,” said Lisa D’Affronte, DDS, article author. “This has led to various systemic health concerns, so it should be a priority to develop alternatives to plastic that are more environmentally friendly.”

The authors’ research delves deeply into the systemic implications of microplastics, including

• Food Sources – salt, fish, and other seafood
• Dental Sources – toothpaste, floss, dental composites, denture base
• Opportunities to Reduce Exposure in Dentistry – plans to develop alternative synthetic polymers to reduce the vast amounts of MP pollution. Bacterial cellulose sheets are a potential alternative, as they are biodegradable and have strong mechanical properties.

The General Dentistry review:

• Defines microplastics and outlines major environmental exposure pathways, including ingestion and inhalation.
• Summarizes emerging research on potential systemic effects involving cardiovascular, endocrine and neurologic systems.
• Identifies common dental sources, including certain toothpastes, toothbrushes, floss, resin-based composites, dentures and orthodontic aligners.
• Highlights opportunities for innovation, including alternative materials and improved waste management.

“Although dental offices use a lot of plastic materials, there is still not enough evidence to show that they are large contributors to the overall problem,” said D’Affronte. “Regardless, dental offices must also take care regarding proper waste disposal, and protection of staff and patients from aerosols created during practice. I also want to stress that regular dental care is much more critical to overall health than any potential exposure to microplastics in the dental office.”

AGD emphasizes that preventive oral hygiene remains essential and encourages ongoing collaboration to develop environmentally responsible solutions.
