“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”

- JLJanet L.Verified BuyerReviewed By: CustomerYesterdayReviewed By: CustomerReviewingFree Expanding FlossRated 5 out of 5 starsLove this floss, it's magical
I love how this floss grabs onto my teeth and pulls away any debris. I'll be switching to this floss from another brand once I'm 100% certain, I'm at about 89% right now. Excellent product, well thought it

- LALeland A.Verified BuyerReviewed By: Customer2 weeks agoReviewed 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.
BOBURST Oral Care2 weeks agoWow - this made our day! We're so happy the Burst floss checks all the boxes for you. Thanks for the love (and the fanny pack backups)! 🖤
