Looking to up your dental game with safe, eco-friendly dental floss? We've got you covered with our top picks for the best non-toxic dental floss options. These selections cater to eco-conscious individuals who prioritize not only their oral health but also the health of the environment. Here's our curated list of products that promise to keep your pearly whites sparkling, free from harmful toxins.

Chemicals Found in Traditional Floss

  • PFAS (Per- and Polyfluoroalkyl Substances): Often used to create a smooth, gliding texture, PFAS chemicals are linked to a host of health issues.
  • Petroleum-Based Wax: Many flosses are coated with waxes derived from petroleum, a non-renewable resource with potential health risks.
  • Artificial Flavoring: These synthetic additives used to enhance taste can have undisclosed chemicals that may affect your health.
  • Teflon: Some floss brands use this material for its non-stick properties, but it can shed microplastics and contains compounds that have raised health concerns.

Frequently Asked Questions

Q1. What Are the Main Benefits of Using Non-Toxic Dental Floss?

The use of non-toxic dental floss ensures that you're not exposed to potentially harmful chemicals such as Teflon, petroleum products, and artificial flavorings that can be found in conventional flosses. Additionally, they often come in sustainable packaging which helps to minimize your environmental footprint.

Q2. Is There a Difference in Effectiveness Between Non-Toxic and Regular Floss?

Non-toxic flosses are designed to be as effective as regular flosses in removing plaque and debris between teeth. Some may offer unique features such as a woven texture that better traps particles or ingredients like hydroxyapatite to support enamel repair.

Q3. Can Vegans Use Silk Floss?

As silk is an animal product, it may not be suitable for vegans. However, many eco-friendly brands offer vegan floss made from plant-based materials or recycled plastics, providing an alternative that still adheres to eco-conscious principles.

Q4. What Can I Do With My Old Plastic Floss Containers?

Recycle them if your local recycling system accepts them. Alternatively, some eco-conscious brands offer mail-back programs, or you can repurpose the containers for small storage needs or crafts.

Q5. Are Non-Toxic Dental Flosses More Expensive Than Regular Ones?

The price of non-toxic flosses can be slightly higher due to the sustainable materials and ethical manufacturing practices involved. However, the long-term benefits for both personal health and the environment can outweigh the initial cost difference.

Q6. What is the Difference Between String Floss and Woven Floss?

String floss and woven floss differ primarily in their texture and design. String floss is typically smooth and thin, designed to slide easily between tight spaces in the teeth. It is effective for removing plaque and debris but can sometimes be abrasive, especially to sensitive gums or tight contact points. Woven floss, on the other hand, has a textured, thick design that provides a larger surface area to grab and remove plaque effectively. It tends to be gentler on the gums and is highly recommended for individuals with more space between their teeth or those who require a more substantial grip on the floss for effective cleaning.

Q7. Does Dental Floss Expire?

Most dental floss products do not have an expiration date because they are considered stable, non-perishable items. However, over time, the effectiveness of the floss may decline, especially if it is flavored or coated with natural waxes and oils. To ensure the best quality and performance, it's advisable to use floss within a year or two of opening. Make sure to store your dental floss in a cool, dry place and keep it sealed to maintain its integrity and prevent it from degrading.

Q8. Can Floss Be Used in Conjunction With Dental Tape?

While both dental floss and dental tape serve the same fundamental purpose—cleaning between the teeth—they differ in their form and usage. Dental tape is broader and flatter than traditional string floss, which some people find easier to slide into tight spaces without snapping. It's possible to use both floss and dental tape in your oral care routine; however, it's not necessary to use them simultaneously. Whether to choose floss or dental tape primarily comes down to personal preference and the specific needs of your dental health. If unsure, it's best to consult with a dental professional to determine which product is best suited for your individual oral care regimen.

Q9. Should You Floss Up Against Your Gum Line?

Absolutely, flossing up against your gum line is a critical component of a thorough oral hygiene routine. The area along the gum line and the spaces between teeth are common sites for plaque accumulation and not typically reached by a toothbrush. When flossing, it's important to gently slide the floss against the sides of each tooth and beneath the gum line to remove plaque and food particles effectively. However, care should be taken to avoid snapping the floss into the gums or being too aggressive, which can cause irritation, bleeding, or damage to the gum tissue.


Choosing non-toxic dental flosses is a small step that can herald significant health and environmental changes. These products not only offer a safer alternative to regular floss but also provide different features such as a thicker floss option, thinner floss option, waxed floss or unwaxed floss. In addition, they provide a stellar flossing experience and can help prevent gum disease and effectively remove plaque and food particles. Whether for personal preference or ethical reasons, each dental floss on this list has been crafted with care, from sustainable sourcing to conscientious packaging. Happy flossing, sustainably!
