"I love the BURST floss for its color! The black helps my patients see the plaque removal and the expanding technology has more surface area to grab bacteria."

- Kim F., RDH & BURST Ambassador

Less gunk = better breath

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.”

    Best floss available today!

    I’ve been trying to find a great floss ever since the expanding floss I used to use was discontinued. Finally stumbled upon Burst and absolutely love it. It’s strong, feels like it’s really cleaning my teeth, and doesn’t shred or split. I took some in to my dental hygiene appointment today and they were really excited about it. Gotta love the funky black color too!!

    Love the quality of the floss for the ability to remove food that gets stuck in between the molars.
