I was flossing twenty minutes ago and the floss jammed in between two of my teeth. I couldn't pull it out. I pulled and yanked and ended up tearing the bloody stuff, so I was left with floss in between my teeth. Using more floss to get it out has resulted in a few metres of floss being used as every time I try to floss that gap, the new floss rapidly frays and tears into two! I must have sharp teeth.. So now I'm going to bed feeling like someone's sitting on my jaw. It's not painful. Just bloody annoying! They need to design stronger floss.
