Made with 100% natural mulberry silk and plant-based candelilla wax, MouthFlora Dental Floss helps clean between teeth with a smooth, simple glide. It’s a natural alternative to synthetic floss, made without microplastics, PFAS, PFOA, PFOS, & plastic polymers.

What makes MouthFlora Silk Dental Floss different?

MouthFlora Dental Floss is made with 100% natural mulberry silk and waxed with plant-based candelilla wax. It’s designed for users who prefer a cleaner-material alternative to synthetic floss, with no plastic polymers in the floss material.

Is natural silk as strong as nylon floss?

Natural silk is strong for a natural fiber, but it does not behave like synthetic nylon or PTFE-style floss. It has less stretch and no synthetic reinforcement, so gentle, controlled flossing is recommended—especially between very tight teeth.

Is this floss plastic-free?

The silk floss itself is made without microplastics, PFAS, PFOA, PFOS, & plastic polymers, making it a cleaner-material alternative to conventional synthetic floss.

Is it good for tightteeth?

It is designed with a smooth, waxed glide to help clean between teeth, but very tight contacts can be challenging for any natural floss. If your teeth are extremely tight, guide the floss slowly with a gentle back-and-forth motion instead of forcing or snapping it through.

Is it flavored?

No. It is intentionally unflavored for a simple, mild daily flossing experience without strong mint or added flavor.

The MouthFlora Philosophy

We believe better oral care starts with small daily choices.


Flossing is one of the simplest habits for supporting a cleaner, healthier mouth — but the materials you use everyday matter too. Many conventional flosses rely on synthetic fibers, plastic-based materials, or unnecessary coatings. MouthFlora takes a more thoughtful approach with natural mulberry silk, plant-based candelilla wax, and a cleaner-material formula made without microplastics, PFAS, PFOA, PFOS, or plastic polymers.


Our goal is simple: create oral care products that fit naturally into your routine, feel good to use, and reflect a more mindful approach to everyday wellness. Because a healthier smile should never feel complicated.

Is it PFAS-free?

Yes. The silk floss is made without PFAS, PFOA, PFOS, microplastics, or plastic polymers.

The floss itself is made without plastic polymers. Because the dispenser and packaging may contain other materials, we
describe the floss material specifically rather than calling the entire product plastic-free.

Is it suitable for tight teeth?

It can be used between tight teeth, but very tight contacts require a slow, gentle back-and-forth motion. Avoid snapping or
forcing the floss through.

Can natural silk floss break?

Yes, it can break if forced through very tight teeth. Natural silk has less stretch than nylon, so gentle, controlled flossing is
recommended.

Is it gentle on gums?

The smooth silk fibers and plant-based wax help create a soft, comfortable feel along the gumline. As with any floss, gentle
technique is best.

How long is each roll?

Each dispenser includes 50 m / 54.7 yd of natural silk dental floss.
