There are many aspects to a dental routine that are important.  Flossing is one that is easily overlooked or goes by the wayside.  Some reasons for this are time, patience, and thinking it is not really that important.

Do you know why it is important to floss, why non-toxic floss is a must, and the best types and brands of non-toxic floss to use?  

I have to be honest, it is hard to find a balance that will please everyone.  There seems to always be a negative-seen side to any aspect, even if it is going natural and organic.  This controversy can occur in the process of extracting the materials, the type of material used, where the material comes from, as well as the the production process.

Scan below to see which material source causes the least controversy for you, and see which one is the best fit for you.  

In this post, find out the best non-toxic floss brands that will bring your dental health to the next level, and why non-toxic floss is so much better than conventional floss.

PFAs in Conventional Dental Floss

What are PFAs?

PFAs are poly-fluoroalkyl substances, or per-fluoroalkyl substances.  These elements are found in household products and drinking water that get into the blood stream and contaminate the body.

PFAs are synthetic chemicals that were originally patented in the use of Teflon (a nonstick cookware).  These harsh chemical compounds are resistant to oil and water.

According to this journal article, a recent study noted that higher levels of PFAs were found in the blood stream of women who flossed with oral-B Glide floss versus women who did not use the same dental floss.

 PFAs Affect the Immune System and Overall Health

PFAs negatively impact the health of the body.  Any way that you are able to avoid these harsh chemicals, is a step in the right direction and a step that must be taken.

The follow are ways that PFAs affect the immune system of the body:

  • This study shows a a strong correlation between these chemicals and suppression of the immune system.
  • Neurological development is possibly altered irreversibly when these chemicals enter the bloodstream.  A new study links tooth loss to cognitive decline risk.
  • The metabolism is also impacted by the ingestion of PFAs.  Since the PFAs enter the water supply system, it is inevitable that the chemicals will be consumed.
  • Thirdly, pre and postnatal development is also at risk due to chemical invasion.
  • Changes in enzymatic production in the liver, increased cancer risk, and lower birth weights have also been founded to be risks.
  • Another problem with PFAs is that they are endocrine disruptors.  The endocrine system involves the regulation and modulation of hormones.
  • Thyroid problems are another health issue that has been linked to dental health.  
  • Finally, there have been many findings of a periodontal pathogen known as g. gingivitis showing up in plaque build up of the artery wall according to this source.  Heart disease is another 

The Benefits of Non-Toxic Dental Floss

  • Flossing removes food particles stuck between the teeth decreasing the risk of decay.
  • Secondly, flossing helps rid the mouth of bacteria.  This helps fight off gum disease.
  • Next, flossing decreases the worsening of bad bread due to lesser bacteria in the mouth.
  • Non-toxic and organic dental flosses provide you with this without additional harmful chemicals and toxins entering into your body.
  • It is important to floss on a daily basis, preferably every time you brush your teeth.  There are dental flosses that work better for different teeth, and this includes those that have braces.  

Non-toxic Floss Materials

There are several types of dental floss materials to choose from.  Below I have grouped them according to which ones are more Eco-Friendly.  All materials have different benefits and strengths.

Eco-friendly materials

Eco-Friendly Floss


Bamboo floss is a sustainable resource as well zero waste.  It is both compostable and grows quickly without the need for pesticides. 

However, some companies pair bamboo with another material to make it stronger and more durable.  If this is the case, this affects the zero waste aspect.

Below, I have listed the materials used in each non-toxic floss brand.


This material is known as Ahimsa silk or peace silk. 

Silk floss is sustainable. It decomposes quicker than traditional floss materials such as nylon.  Also, it is easily produced.   

The term peace silk assures you that the silk is a cruelty-free dental brand.  These brands use peace silk because this means the silk is sourced after the silk worms hatch, allowing them to live.  Make sure the brand uses peace silk for it to be cruelty-free.

Also, it is very important to know that silk worms are heavily processed and treated in some cases.  Silk can involve the use of chemicals when sterilized.  This is something to look for when searching for a non-toxic floss.

Natural Wax

Beeswax and calendula are used in coating natural dental flosses. The wax allows the dental floss to easily glide between the teeth.

These are safe sources of wax. Beeswax is of course sourced from bees.  Candelilla wax is sourced from small leaves of the candelilla plant.   Of course, these sources still need to be void of toxins.


Another material used to make floss is corn.  It is renewable, compostable, and vegan.

However, corn is often heavily applied with chemicals.  Therefore, I have only included trusted floss brands below that use no chemicals in their floss, even if it comes from corn.  Look for organic and Non-GMO.

Less Eco-Friendly Materials


Nylon floss is a preferred dental floss material for some companies for different reasons.  Some companies feel is is a safer choice with less chance of chemical contamination, while others feel it an overall stronger and better material.


Polyester is incorporated into the material of some floss brands.  Others use it as a sole material ingredient.  This strengthens the floss reducing breakage.

Other Ingredients

charcoal Floss


Whitening of teeth is a benefit of using floss that has been infused with charcoal.  However, there has been indication of possible enamel stripping with overuse.  So be cautious of the amount used in your dental routine.

Coconut Oil

Coconut oil is a natural antibacterial ingredient which makes it ideal for teeth protection.  Many flosses and oral brands include it as an ingredient in their oral care products for this reasoning.

Essential Oils

Essential oils are sometimes included to give the floss a flavoring.  Pure essential oils should be only used, and it is preferable if they are organic for best quality insurance.


Xylitol is an excellent source to see included in a floss option.  It is a great fighter against bacteria and promotes a healthier mouth environment.  This journal article states the following:

Xylitol reduces the levels of mutans streptococci (MS) in plaque and saliva by disrupting their energy production processes, leading to futile energy cycle and cell death.
It reduces the adhesion of these microorganisms to the teeth surface and also reduces their acid production potential.

These are a great lollipop source made with xylitol in place of sugar.  They are know to help fight bacteria as well as positively impact oral health. We personally really enjoy the tasty treat.

Floss Brands I Don't Recommend

After contacting the company or not being able to verify additional information, there are a couple popular natural floss brands that I do not recommend.  

Saint Dental Floss

Saint dental floss is a company that states that they are strictly an organic and non-GMO making it seem like a prime choice.

However, after contacting the company to see if pesticides are used on the corn used in the floss making process, they said the following:

Unfortunately, we can't guarantee no pesticides were used in the treating of the corn during manufacturing.

This does mean that there are pesticides used, however, I choose brands to the best of my ability that have the cleanest ingredients.  Since this cannot be verified, I personally choose to not use the brand and want to offer the information to you for you to decide for yourself.

Due to this being the case, I am not able to recommend using this company as a best option.

Ingredients:  Corn, Coconut oil, Xylitol, Vegan wax 


This company offers dental floss options, however, I only recommend buying the mint floss. I do NOT recommend the other flavored dental flosses.  

It does not use materials with toxins, PFAs or parabens, however, their flavored flosses use both natural and synthetic fragrance sources.

Cocofloss holds the leaping bunny certification, meaning they use cruelty-free practices.  Another important aspect of this company is that a portion of Cocofloss' proceeds go to The Wildlife Conservation network.

Coconut oil is used in the production of their floss giving it an anti-bacterial edge as well.

However, due to the use of synthetic flavoring being used in the other flavored flossed, I personally would not purchase the flavored brands.  

They state that the flavoring specifically comes from a shop in Italy, but it is unclear on the exact process for the flavor creation.  They did not reply to any of my further questioning.

I am also skeptical because this information was a bit hard to find on their website, only being highlighted after scanning over specific material.

Since the details are not clear on the process for the synthetic fragrances, they are off the best options list.

Ingredients:  Polyester fiber, Coconut oil, Mint natural flavors, Microcrystalline wax
