Zero-Waste Floss - 10 Best Choices for Eco-Friendly Oral Hygiene

Floss is a dentist's best friend and a sure way to make your teeth happy. What tiny, innocuous product is more important to our health than a little strip of dental floss—perhaps only 12 inches long? Further, we can directly connect dental hygiene to our cardiovascular, digestive, and overall well-being. Read on as we make a case for zero waste floss and list 10 of the best. 

Alongside a clean between the gaps, that inexpensive, cinnamon or mint-flavored unbreakable thread creates several health and environmental hazards. The good news is that we have alternative types of floss that don't carry the same risks and eco-burdens as traditional plastic-based flosses.

We'll come back to a discussion of the downsides of traditional floss. First, however, let's look at ten of the best alternative brands for zero-waste floss options.

1. Dental Lace Silk Floss


Dental Lace offers a natural silk dental floss with two spools lasting for four months, using the recommended 18 inches per day. Aside from the refillable glass container, their packaging is also sustainable. The box is made out of 100% post-consumer paperboard, while the labels are made from sugar cane fiber.

Eco-Friendly Natural Silk

Because cruelty-free silk is not synthetic, it is subject to breaking. This is particularly true if you use it between exceptionally tight spaces between teeth. So, there is a little learning curve.

It is waxed with plant-based vegan wax and infused with essential mint oil to make it glide between the teeth, and because it's all-natural, it's also suitable for sensitive gums and looking after the oral health of the family.

Simple tastes and effective uses are the epitomai of RDHopes reusable glass bottle floss holder with an aluminum top filled with bamboo charcoal floss.

Benefits of Bamboo Zero Waste Floss

RDHopes' kit comes with zero plastic content. Britany, the merchant, and owner of RDHopes work in the dental industry. She creates and presents this product as a way of protecting the environment, saying,

“Working in the dental field and seeing the amount of waste from just one office is astounding. My goal is to shift dental products in the direction of reuse. If you can reuse this jar for the whole year, that’s an estimated 12 floss containers you save from being thrown out!”

How Often Should You Floss?

Research from the American Dental Association highlights the importance of flossing to remove foot and plaque that toothbrushes fail to reach. Flossing every day is their recommendation to maintain your oral hygiene.

Why do we Need Eco-Friendly Dental Floss, Anyway?

It may be easy for us to become somewhat jaded about the ecological dangers of dental floss when we stop thinking of the Texas-size island of waste plastic floating unassailably in the Pacific Ocean. 

It's equally understandable to think that you are just one person and, in the face of the plastic-flossing habits of nearly eight billion people, what difference does it make if I use regular dental floss?

It makes a difference, first of all, because you are not alone. For each of us who adopts sustainable living, it's that much less plastic to pollute our planet. One first, small step in living a zero-waste life is in forsaking plastic-based floss.

The problem with regular floss

Traditionally they make traditional dental floss of nylon which does not biodegrade. To be precise, it's estimated that nylon filaments will remain intact without breaking down for 500 years. It is also not recyclable.

We may find ourselves tempted to believe that floss, doled out and tossed in the trashcan or, often, into the toilet, isn't going to cause that much harm even if it isn't biodegradable.

Unfortunately, that is not the case. Americans use about 3 million miles worth of floss a year to get to those hard-to-reach areas between their teeth. When used floss gets flushed, it is small enough to escape many capture points in the water reclamation grid and, thus, it frequently ends up on fresh and oceanic waterways. 

Aquatic wildlife frequently ingests these pieces of plastic. Because it does not break down in any creature's digestive tract, it inhibits and can kill animals who consume it.

Dental Floss Flavoring

What about that minty flavor that comes with most types of standard floss? That is actually fused to the filament with plastics, often through perfluoroalkyl substances (PFAS). Science has linked these chemicals to numerous health issues, including certain cancers, elevated cholesterol, colitis, weight gain, and infertility. 

On the other hand, you'll find the best zero-waste floss choices flavored naturally with peppermint oil or organic tea tree oil, which possesses antibacterial qualities perfect for dental health.

Dental Floss Packaging

So, plastic floss is a synthetic material coated with suspect chemical compounds. Of course, they have to package it in something. Typically it comes in a plastic container. Yes, it's recyclable.

However, studies have shown that between 8-9% of plastics get recycled. That means 91 or 92% of those little plastic containers don't make it to recycling.

Ultimately, they aren't as pernicious as other plastic problems. Still, for perspective, it's worth noting that in an average year, the number of plastic floss containers in the US that don't make it to recycling would fill a football field to a height of six stories. Oh yes, that little plastic container—doesn't it come wrapped in a plastic blister pack?
