I found that, after camping for a week (it was meant to be 3 days) without a toothbrush, I now feel compelled to floss every time I brush, or else my teeth don’t feel clean. Which is great! So I’m finally using up the end of what is probably floss 10 years old (yes, really – I remember it being in my dad’s cupboard, where I saved it from, at least that long ago!), and getting lovely clean teeth in the meantime!
