## Description

Flossing is an integral part of any thorough oral care regimen, but not all flosses are created equal. Our Natural Biodegradable Silk Floss takes us back to a time before the nylon of today’s floss took over — when floss was made of pure, inviting, luxurious silk. Free from the toxins found in similar products, RADIUS’ silk floss glides easily between teeth for a meticulously clean finish. Plus, our silk floss is the only biodegradable and compostable floss on the market today Ingredients: Natural Silk Thread, Carnauba Wax

Review: No PFAS or other chemicals and strong enough when using the proper side-to-side technique - I use this now to replace Glide floss. It is the thinnest out of all the non-petroleum-based flosses, but it is somewhat weaker. It is plenty strong when you use the technique of gently going side-to-side (no tension on the floss) between teeth pinch points. After you're past the pinch point, you can apply more pressure to the sides of teeth by increasing the tension of the floss and you're fine. There is enough friction between the pinch points to remove plaque there using this method and avoids breaking floss. BPA, PFAS, etc. today--more acronyms tomorrow for what's considered safe now (polyester, nylon, etc.). Also, it stands to reason that the gum tissue between teeth is very sensitive and highly absorbant, so any chemicals will be readily absorbed into the body. Add repeated long-term exposure and the fact that flossing can make your gums bleed (chemicals possibly being directly routed into the bloodstream), this floss makes the most sense. They do need to work on their quality control, as some batches appear to be weaker than others. Maybe someone will develop spider silk floss soon.
Review: Don’t waste your $! Overly expensive floss that rips and shreds in an unsturdy container - I purchased this floss because I was recently diagnosed with several contact allergies, and this is one of the only flosses that does not contain any of my contact allergens. I really wanted to love this floss because it is much more eco-friendly and sustainable than its competitors. However, this floss is not good. First of all, the floss itself is very thin and prone to tearing with minimal force. My teeth are normally spaced apart, without any especially tight squeezes. And the floss broke after only flossing two teeth! Because the floss is also pretty thin, I felt like it missed bits of food between my teeth that other brands of floss have been able to get. It was especially bad at removing the thin husks from popcorn kernels. Because it’s not very well waxed, it also tended to get caught more easily and I didn’t think it did as good a job removing tartar as other brands I’ve used. I also absolutely hated the container it came in. While I appreciate the fact that cardboard is sustainable, it is just not practical to have a paper container in a damp environment like a bathroom. Plus, the floss kept breaking and I had to keep getting more out with hands that were damp from said flossing, which caused the box to get damp and wilt. The container is also flimsy and not well constructed. On the plus side, this floss is truly unscented and unflavored and did not irritate my sensitive skin. However, because it’s not very effective, very prone to breaking and much more expensive than most drug store varieties, I would not buy this again and would not recommend that anyone else buy it.

## Features

- EXPERTLY DESIGNED: RADIUS Dental floss brings both function and sustainability to the table.
- PLASTIC FREE: Our flosses are packaged in 100% plastic-free packaging. The recyclable outer cardboard box acts as the floss dispenser!
- NO NASTY INGREDIENTS: You won't find any PFAs, glutens, preservatives, artificial swetners, GMOs, unnatural coloring, phthalates, parabens, or any other harmful additives in our floss, ever!
- ORAL CARE BOOST: Our formula uses erythritol, which helps fight cavities better than it's close counterpart xylitol.
- SOFT & SMOOTH: Our biodegradable and compostable floss is spun in candelilla plant wax, derived from candelilla shrubs in the Southwestern US desert. Our floss ensures a smooth glide between teeth for total tooth and gum protection.

### ⭐⭐⭐⭐⭐ Feels like it grabs at the sticky parts where I probably have cavities.
*by Z***K on July 22, 2025*

I got this when I found out over 90% of dental floss have “forever chemicals” similar to Teflon. (For more info on that, I recommend the movie “Dark Waters” with Mark Ruffalo & Anne Hathaway, super good movie.) This floss does not have those chemicals, so I won’t accidentally eat anything toxic that my body can’t get rid off. Anyway, this floss is jot at all “silky”, It sticks and grabs in spots where I guess I must have cavities. Sometimes it breaks off in a spot where my tooth is sharp, and a small bit of the floss gets stuck and I’ll have to work the floss in there a 3rd & 4th time to get it out. I like it, though. I use a waterpik and this floss polishes off a log of residue the waterpik misses.
