My favorite floss
Beeza—February 1, 2026✓ Verified purchase
This floss is thin enough to go in between my tight teeth and expands enough to wear I actually feel like it’s trapping particles. Read more

Great light flavored expandable floss
J.C.—July 4, 2025✓ Verified purchase
Great price for expandable floss and they barely have a strong flavor. It’s a light mint which is great for kids. My kid hates strong flavors and these expand to get out a lot while flossing Read more

Not the expanding floss I was looking for
Colorado—November 8, 2024✓ Verified purchase
It expands after it gets wet but I'm not sure what is the benefit from that. It doesn't expand in terms of stretching - it just becomes fuller and the threads more breakable. So it ends up getting stuck in between my teeth and threads break and I can't get them out easily. I realize there's thread between my teeth after I'm done flossing. I needed a floss that expands so it doesn't break in between the teeth. I do not recommend this product. Read more

Expanding?
Holly—September 18, 2024✓ Verified purchase
I think we have different definitions of expanding. This floss does not expand in the slightest. I'll give it 2 stars because it's floss. You can't really mess up floss. It does the job of flossing. This floss reminds me of sewing thread but a little thicker. I think that's its only perk. Because it's not the super smooth gliding floss, it has some toughness to it so it seems to grab on to the gunk in-between my teeth better than other floss. Read more

Shipping issue

Bought a 2 pack and only received one. Lucky Amazon fixed the problem and shipped out an additional one. Floss was good though. First time using expandable floss and would get again. Read more

My favorite floss EVER!
DC—December 5, 2023✓ Verified purchase
I love the Xpand floss for an extra deep clean. I also use the floss picks, but use the Xpand floss because it cleans SO thoroughly. After threading the floss through my teeth, it stretches and actually expands...it feels like a little brush cleaning in between my teeth and gums, love it! gentle and soft on my gums. My dental hygienist is a huge fan and recommends it to all of her patients! Read more

Good value
Nose Bikes—April 22, 2025✓ Verified purchase
Not sure what expands, but it isn’t the floss. If it did, it would go in your teeth and not come out. Despite the marketing hype, it’s a good feeling floss at a good price. Read more
