Where oral-care plastic hides
How to avoid microplastics in dentistry
Microplastics, the tiny plastic particles that seem to be all over the news, have been getting attention in the dental world, too. From toothbrushes to aligners, plastic is woven through modern oral care.
The good news: Dental sources are only a small slice of your total plastic exposure, and a few easy swaps can trim it further. Here's where exposure comes from, and, if you’re concerned, how to cut back on plastic without stress.
Plastic is a big part of everyone’s daily life, and that includes a dental routine. Plastic can be found in:
-
Toothbrushes with nylon bristles and plastic handles
-
Most floss, which is typically made of nylon
-
Clear aligners and retainers
-
Night guards
-
Fillings made from tooth-colored composite
This use of plastic can be beneficial. For instance, a composite (white) filling contains plastic but is still a very effective treatment for cavities.
Simple, low-effort plastic swaps
If you are concerned about plastic in your oral health routine, there are simple swaps you can make to reduce your exposure:
-
Rethink your brush: Look for a toothbrush with a bamboo handle. You'll still replace it every three to four months, just with a little less plastic.
-
Try a different floss: Silk or uncoated floss is widely available, and skipping coated flosses helps you sidestep certain “forever chemicals,” too. Just make sure they still carry the ADA-approved label.
-
Mind your toothpaste: Choose products labeled free of plastic microbeads, which are tiny scrubbing or decorative agents that are sometimes added to toothpaste. The FDA banned microbeads over a certain size in 2015, so this is an easy tip to follow.
If you store your toothbrush or floss in a plastic container, don’t leave them in the heat — like in a hot car while traveling. This can cause microplastics to seep into the toothpaste or onto the floss, although there’s no clear research on the risk this could cause.
Other ways to reduce plastic exposure
Your daily oral health routine is a minor part of your daily plastic exposure. Filtering your tap water and cutting back on single-use plastics around the house will likely do more than any single oral-care change.
Small swaps, healthy smile
Reducing microplastics doesn't require an overhaul. All it takes is a few thoughtful choices next time you buy oral health supplies, and an open conversation with your dentist about your options. Make easy swaps, continue to brush and floss your teeth, and let the experts help you separate real risk from noise.
