ou only need to have visited a dentist once in your life to know how important daily flossing is for the health of your teeth and gums, but is there anything else your floss could (or shouldn’t) be doing?

Reports have come out in recent years showing that some traditional dental flosses might be exposing people to harmful chemicals. There are also serious sustainability concerns with the waste that regular flosses create. We’re here to floss out all those issues and get clear on what clean, non-toxic, vegan flosses can offer instead.

Not only do we have a recommendation list with 8 of the best non-toxic dental flosses, but we’ve broken each option down by their sustainability stats, ingredients, packaging, etc., so that you can make the most informed decision for your health and sustainability journey.

What Traditional Floss is Made From (And the Harm It’s Doing)

In the US at least, dental floss brands aren’t required by federal law to disclose what’s in their products. This means that there are an alarming number of brands that have managed to sneak in potentially harmful materials and chemicals.

Let’s take a closer look at what’s in traditional floss and the unwanted impact it may be having:

  • Petroleum-Based Nylon and Polyester Fibers: Used for their smoothness and ability to glide easily between teeth without breaking, these synthetic fibers unfortunately cannot be recycled and take decades to biodegrade. It’s also not ideal to be using something in your mouth made from petrochemicals as they’re known endocrine disruptors, might be carcinogenic, and can increase the risk of heart disease.
  • PFAS: These chemicals are in many consumer products, including non-stick kitchenware, clothing, food packaging, and getting into our mouths and body through some dental flosses. They tend to be in the synthetic waxes on flosses and have been found in flosses from multiple brands, including Oral-B, Colgate, and Crest.
  • Synthetic Waxes: Usually made from petroleum, it again means that a known hormone disrupter and possible carcinogen is entering your mouth. There’s also an environmental cost, as the petrochemical industry has been associated with pollution and huge carbon emissions.
  • Sodium Laurel Sulfate: SLS often appears in dental hygiene products as a surfactant and can help improve plaque control and bad breath, but it’s also a known irritant best avoided by those with sensitive teeth or gums.
  • Fluoride: Similar to SLS, fluoride offers dental health benefits but isn’t always great for those with sensitivities. Furthermore, this chemical is also a known endocrine disruptor which means it can disturb the normal function of the thyroid, reproductive system, and pituitary gland.  

What Non-Toxic Floss is Made From Instead

The main difference between non-toxic dental floss and regular versions comes down to the materials used for the floss thread and wax. The best non-toxic floss options are leaving behind nylon and polyester thread in favor of natural, biodegradable materials such as charcoal, cornstarch, and bamboo fibers. This helps reduce waste and limits your exposure to synthetic materials.

Non-toxic brands are also doing wax differently (There is some debate on whether floss should have wax on it at all)l. Generally, it helps strengthen the thread and make it more maneuverable, and with cleaner brands, you’re not getting any petrochemicals in the mix.

Instead, non-toxic flosses mainly use candelilla wax. This blend of plant-based waxes is hypoallergenic, PFAS-free, and like so many of the ingredients in natural floss alternatives, biodegradable as well.

Our Criteria for Non-Toxic and Sustainable Floss Recommendations

Here’s a breakdown of the criteria we use when deciding which non-toxic and sustainable dental floss brands to recommend:

Non-Toxic

  • No nylon or petroleum-based materials.
  • Transparency regarding the ingredients and materials used to create the non-toxic floss.
  • PFAS-free.

Sustainable

  • Some kind of sustainable packaging, be it plastic-free, recyclable, or refillable, to help decrease carbon footprint.
  • Natural fibers in the floss that can biodegrade.
  • An effort from the brand to support sustainability issues, such as donating to 1% for the Planet.

Vegan

Besides being certified vegan in some respect, these are the specifics we looked for in vegan dental floss:

  • No silk fibers.
  • No beeswax.
