Microplastics: what we know

June 15th, 2026

More research is being conducted and released on microplastics (small pieces of plastic <5mm) and nano-plastics (even smaller pieces of plastic) that can be found in our environment and, increasingly, in our bodies. Modern life includes exposure to many different types of plastics, especially food and drink containers, single-use plastics, inhaled particles, and medical/dental products.

The health effects of microplastics are still unclear, but the benefits of daily dental care, including brushing and flossing, are well established and confirmed by research. Good daily oral hygiene remains very important for avoiding costly, painful dental problems.

You can limit exposure to microplastics by:

  • Avoiding single-use plastics. Drink tap water from a refillable metal or glass bottle. Tap water also has the added benefit of containing fluoride (in most areas), which helps protect your oral health. Next time you pick up take-out, use your own silverware if you’re eating at home.
Reusable containers for leftovers
  • Transitioning your food storage to glass containers. If you use plastic containers, avoid placing them in the microwave or dishwasher. Transfer the food to a plate or a glass vessel if you plan to heat it in the microwave. Handwash plastic food containers.
  • Looking for dental products without plastic coating. Some companies have reformulated their floss to use an alternative to plastic. Look at labels for ingredients like beeswax that can help floss slide between teeth. Another option is switching to silk floss, bamboo floss or a water flosser. If you have questions about which products are right for you, talk with your dentist or hygienist.
  • Talking with your dentist or orthodontist regarding alternatives to plastic aligners for braces.
