“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”

“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.”
“Hands down (or fingers up) my favorite floss! I love that it is black and I can see all the little nasties coming out of my teeth and gums. l love that it is helping remove the stains from my teeth due to my coffee addiction. And it tastes AMAZing!”
“BURST floss is my favorite to date and I'll tell you why. The black color makes it so easy to SEE your progress!!! The aroma is fantastic with essential oils to help with gum health! lt's fine enough to reach all those hard to get to places also!!!”

- LALeland A.Verified BuyerReviewed By: CustomerYesterdayReviewed By: CustomerReviewingReplacement FlossRated 5 out of 5 starsBest floss for gapped teeth, and for any teeth for that matter
I love Burst floss. I bought this floss when I was researching which floss was the thickest floss out there. I actually used to use the polar oppposite, Glide, and realized it was a) not good for my gapped teefs, and b) just not a good floss overall.
I have a missing permanent tooth and my teeth are overall far from each other because of it - not necessarily GAPPED, but there are bigger spaces in between my teeth where food can get stuck in, so I was in the market for a thicker floss because the one I was using, Glide, I pretty much had to fold over so it could be thicker - and other flosses just felt too thready and not easy to use.
Burst floss I literally will never change unless they start using yarn for floss. I even have dang subscription for it to come every 3 weeks or something, I forget, AND I buy a good amount of replacements for each bag I carry with me - my two fanny packs, my work bag, and each bag has a second replacement floss just in case the first one gets low.
Burst floss is goated - no, no one's paying me, I just have a thing for flossing.

- DMDavid M.Verified BuyerReviewed By: Customer1 week agoReviewed By: CustomerReviewingReplacement FlossRated 4 out of 5 starsExcellent & expensive
The best floss but it does cost. It really is next level, though it is thick so some people might not like it but I love it. My only gripe is how expensive and difficult it is to get the refills. I never see refills in stores and buying direct throws $5 more for shipping on an already expensive item. Subscribing still incurs shipping cost.
BOBURST Oral Care1 week agoThanks for the honest and thoughtful review. We're so glad you love the floss! 😊 We hear you on the refill concern. While single refill orders have a $1 shipping fee, many customers choose to get two at a time, which ships free (for expample 2 every 24 weeks instead of 1 every 12 weeks). If you’d like help adjusting your subscription or placing an order, please feel free to reach out - hello@burstoralcare.com - we’re always happy to help!
