The 8 Best Lip and Oral Care Products of 2021, according to Health Editors

“We’ll be the first to admit that we don’t always remember to floss—unless, of course, it’s with this innovative version. The fibers expand when they come in contact with saliva, which means the floss strands glide between your teeth easily and take more gunk out with them. The charcoal coating helps absorb stains and dirt (so much you can actually see it on the floss if you want to gross yourself out). The refillable packaging is just icing on the cake”

“This floss expands when it touches saliva, so it hugs every nook and cranny between your teeth. The charcoal coating helps reduce stains but also means you can see everything that comes out of your mouth (gross but satisfying).”

“This innovative string takes flossing to the next level. It expands upon contact with saliva so that it can remove even more plaque from between your teeth.”

Got questions?

How is the BURST floss different from other floss?

Unlike traditional options, BURST Floss has been meticulously designed to remove up to 85% of plaque from areas that regular toothbrushes can't reach and 2x more plaque than unwaxed dental floss. So, get ready for a thorough clean! Its uniquely black color not only provides immediate, gunk-ridding satisfaction by highlighting debris removed from between your teeth but also boasts a high-quality textured thread with adsorptive xylitol coating that effectively pulls away stubborn stains and aids in fighting cavities. Additionally, our floss is mindfully made, being cruelty-free and vegan, with a natural Mint Eucalyptus aroma and free from parabens, BPA, or PFAS. To top it off, it is housed in an eco-friendly 95% recycled plastic case, reflecting our commitment to sustainability. Boom!

Our floss stands out in the market due to its unique features and careful creation process. Developed in collaboration with a community of over 40,000 dental professionals, the Expanding Floss is the result of extensive testing and consultation with this enthusiastic team, setting it apart from all other dental floss options on the market. We actively sought the input of these experts, valuing their insights to create a product that truly caters to your oral health needs.

Why does the BURST floss expand and how?

The BURST Floss is made with technology that reacts to the saliva and friction in your mouth, which then causes the filament to expand. The expansion of the filament will reach into the nooks and crannies in your teeth to get rid of your plaque.

Can I use the BURST floss with implants?

Is the BURST floss waxed?

Huge floss spool is awesome, with three in the family pulling from, subscription renewal is the way to go.

Convenient floss with nice dispenser
I love the floss dispenser. Sometimes the floss shreds because the space between my teeth is tight. Other than that I find it easy and convenient.

We’re so glad you love the floss dispenser 😊 Our expanding floss is designed to gently clean between teeth and adapt to different contacts, but everyone’s dental work and spacing is unique. Tight contacts, fillings, or dental appliances can sometimes increase the risk of shredding. Many customers in your situation find a water flosser works great for those hard to reach spots.
