But here’s a quick summary of what both of them basically said about disposable floss picks.
All in all, you shouldn’t use disposable picks more than once.
In other words:
You should change the floss pick after each session of flossing.
You may also need to use more than one floss pick per session of flossing if the floss starts to fray or stretch.
While disposable floss picks and reusable flossers are hygienic and healthy to use when they’re clean…
It’s usually not hygienic to use disposable flossers more than once because of two reasons.
The floss on these single-use flossers may no longer be as effective as it should be.
Leaving out a used disposable floss pick can (re)introduce bad germs into your mouth.
Only in very select cases, when the single-use floss pick looks in superb condition…
And when you have no other choice…
Might it be ok to thoroughly rinse and clean it off for a second use. But this isn’t advisable.
If you want to reuse a disposable flosser:
It may be better to use an eco-friendly floss pick, like the Element reusable floss holder, instead.
