While conventional floss is not biodegradable, there are zero waste alternatives like bamboo floss and silk floss you can try instead.

When you think about your daily oral hygiene routine, you probably don’t stop to consider the environmental impact of that little strand of floss. But here’s a surprising fact: traditional dental floss is a sneaky contributor to plastic pollution.

If you’re wondering, is floss biodegradable?, you’re not alone. In this blog, we’ll dive into the science of floss biodegradability, the environmental impact of conventional floss, and explore some zero-waste floss alternatives that are better for the planet and your pearly whites.

Is Floss Biodegradable?

Usually, no. Most conventional dental floss is made from nylon or Teflon, both of which are synthetic materials derived from petroleum, and so are non-biodegradable.

These materials don’t break down naturally in the environment and can persist for hundreds of years. That means improperly disposed floss can end up in waterways, where it entangles and harms marine life. Not to mention, they’re usually packaged in single-use plastic, adding to the already overwhelming global plastic waste crisis.

That said, there are plenty of biodegradable options you can try instead.

Does Biodegradability Matter? 

According to the National Oceanic and Atmospheric Administration (NOAA), over 8 million metric tons of plastic enter our oceans annually. Dental floss might seem like a small contributor, but every little bit adds up.

Biodegradable products break down naturally, returning to the earth without leaving toxic residues. When dental floss is biodegradable, it decomposes within a short time frame when exposed to natural conditions such as soil microbes and moisture. This contrasts with conventional floss, which can sit in landfills or oceans for centuries.

Using biodegradable floss aligns with the zero-waste philosophy: reduce, reuse, recycle, and rot (compost). By choosing eco-friendly dental floss, you’re keeping harmful materials out of the environment while still prioritizing your pearly whites!

Zero Waste Dental Floss Alternatives

Luckily, there are sustainable and effective dental floss options available. Let’s take a look at some standout alternatives, so you can discover the one that works for you.

"For some reason, I'd never thought of how bad floss is for the environment, not to mention the tiny plastic particles being left in my mouth and body! My husband brought it up one day and I immediately began looking for zero waste floss and this bamboo charcoal floss came up. I am SO glad I gave it a try... I love it. It does not break (normal wax floss always shredded or broke and drives me crazy), it has a mild mint taste, a cute glass refillable container, and is decomposes in around 60 days! I have already subscribed for refills. Thank you for an amazing product." - Caitlin, Verified Customer

3. Electric Water Flosser

For those looking to skip traditional floss altogether, water flossers provide a reusable, long-term solution. Though they require an initial investment, they eliminate the need for disposable floss entirely - it might be worth it for your million dollar smile!

Health Benefits Of Eco-Friendly Floss

Switching to zero-waste floss isn’t just good for the planet; it could also be a healthier choice for you. Many conventional floss brands are coated with PFAS (per- and polyfluoroalkyl substances), also known as "forever chemicals," which have been linked to health risks such as hormone disruption.

Eco-friendly flosses, like bamboo and silk floss, are free from harmful chemicals and use natural coatings, ensuring a safer flossing experience.

How To Dispose Of Biodegradable Floss

To get the most out of your biodegradable floss, proper disposal is key. Here’s how to handle it:

Compost

Most biodegradable floss can be added to your home compost bin. Check the product packaging for specific guidelines.

Avoid flushing

Even biodegradable floss can cause plumbing issues or harm waterways if flushed.

Recycle packaging

Glass or metal containers can be repurposed or recycled, and cardboard packaging can be recycled or composted.
