how long can you keep a FLOSS without it going bad or the expiration dat??

Answer 1

No real expiration date, but waxed floss will lose some of its flexibility and the wax will get 'chunky'. If it's Glide or woven floss, you can use it indefinitely.

Answer 2

There's no expiration date on floss. =)

Answer 3

HELLO,
DENTAL FLOSS HAS NO EXPIRATION DATE. IT DOES NOT GO BAD.

Answer 4

if it rips or breaks when you try to use it its to old will last for years
