GUM Expanding Dental Floss
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
If your gums are regularly bleeding after each flossing round, either you're applying too much pressure with the floss (you don't need to cut your gums) or likely using a low quality floss.
I have sensitive gums and a small mouth, so my teeth have very little space in between them (thanks nature). Thanks to my dentist, I found that using higher quality floss resolved the bleeding completely, because I need to apply way less pressure to get the floss in between teeth, so it never whips/cuts the gums.
Waxed floss is better than non-waxed if I am traveling and forgot to pack it, but expanding floss is miles ahead of both.
I regularly use this one, and haven't had a gum bleeding in months: https://www.amazon.com/GUM-Expanding-Dental-Floss/dp/B01LXFT...
The thread is thinner than waxed/non-waxed thread so it fits more easily, and once you put it in between your teeth, you can remove the tension from the thread and pull it with just one finger -> the expanding thread helps to clean the gunk also from teeth walls and other places that are harder to reach with regular floss.
