Click here to watch a video on how to refill the floss container. Our spools are meant to be unwound from the center, and not from the outside. It might not alway be obvious, but there should be an end of the floss protruding from the inside of the spool. If you can't easily remove it, use a pair of tweezers to grip it and pull it through the center of the spool.

Dental Lace Inc is located in Maine, U.S.  We're  a bunch of passionate planet lovers who are doing our best to rid the world of harmful plastic dental floss. Our 100% silk floss is manufactured and assembled in Italy. Our bamboo charcoal infused vegan floss is made in China.

Dental Lace is proud to offer plastic-free floss using primarily 100% silk. Silk is one of the strongest fibers in the world but can shred or break when dragged over sharp or uneven surfaces.

Some customers with tight teeth or sharp spots have told us that our Dental Lace silk floss sometimes breaks and shreds when they are flossing.

If you are someone with very tight teeth or uneven edges on your tooth surfaces, you might want to purchase one of our Dental Lace Vegan flosses, which are stronger. If you are using our silk floss now or want to give it a try, we offer the following suggestions to reduce the chance of breakage and shredding: 

• 1. Pull the floss straight up and out without dragging it along the sharp edges of the hole in the cap, then cut it using the cap-cutter.
• 2. After you have cut the floss, test the strength by pulling the floss in opposite directions. If it breaks, recycle that piece and use the remaining section to floss.
• 3. Floss the tight or uneven area of your mouth using an up and down motion. And it helps to slow down, just a bit.
• 4. As recommended by dentists, be sure to use new parts of the floss as you move through your mouth. This will ensure that the section of the floss you are using is new for each area of your mouth and will also prevent germs from spreading from one section to another.

Sorry. No. The new containers are a different size. We can't guarantee the new caps will fit on the previous containers.

At this time we do not provide free samples to dental hygiene students but we do offer a 10% discount to all students. Please use discount code: zerowastestudent at checkout.

For years, I’ve carried around dental floss to make sure I could get my teeth clean while at work. Not only were the containers ugly, but I realized that they were rarely recyclable. While it seems like a small thing, it all adds up! So I decided to create my own fashionable, refillable floss containers.

A: The silk floss supplier imports silk cocoons from China, treated only with the first stage of removing sericin (a protein that acts as a natural glue), the "sticky"  component.  The rest of the processing is carried out in Italy.  Our silk floss is sourced from a Seri.co Certified supplier. Seri.co Certification is an independent quality and safety seal for silk, similar to an organic certification for food.  It verifies that the silk meets strict quality and safety standards throughout the entire production process, from raw material to finished product, giving you confidence in what you're putting in your mouth.

The toothbrush handle is fully compostable. The bristles need to be removed or snapped off before composting as they are made from castor oil and slower to breakdown.

Yes! We ship free for all orders over $30!

We no longer ship direct to consumers outside of the US. Our Canadian customers can order through The Soap Dispensary.
