Why our Floss is boss

Our Floss boldly goes where no other floss has been before, expanding between teeth upon contact with saliva. Deep cleaning and developed with BURST Ambassador Dental Professionals, it's an oral care Holy Grail.

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.”

Curious what people think?

Our BURST Ambassador Dental Professionals and customers know their stuff. You should listen to them.

    5 stars all the way

    ’ve tried so many different flosses over the years, but Burst is by far the best! It glides easily between my teeth without shredding, and I love that it feels gentle yet really effective at getting everything clean. The minty flavor leaves my mouth feeling so fresh, and the packaging is sleek and convenient. It actually makes flossing something I want to do every day. Highly recommend to anyone looking to upgrade their dental routine!

    Best Floss

    This floss has to be the strongest floss I’ve ever tried and it’s much appreciated. Usually I have had weak flimsy plastic feeling floss that sometimes just felt like it wasn’t doing what it was supposed to be doing. However, with Burst floss feel like not only does it get the job done efficiently but the sturdiness from it is amazing. Lastly, I know it may be minute and weird but I do like the fact that it’s black floss so you can assure that the food is out between your teeth. Overall, great product and will be making this a staple.
