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.”

“If you didn't like flossing before, you're going to love it now. The feeling of being able to see the nasty that you removed from this black floss isjust so satisfying. Never thought I' II be so excited to floss. Best stocking stuffer to put in every Christmas bag this season. Just reviewing this floss just made me want to eat and floss again.”

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?

Big floss dispenser
I’ve been wanting a big floss dispenser for both my bathroom and dental office — and it’s finally here! 🙌 The smaller one is perfect to toss in my purse, while the larger size is great for home and for using on my patients. This floss is a must have — it expands to grab all the gunk and leaves everything feeling super clean. So happy it’s now available in a big dispenser!
