My dentist is always after me to floss once a day. Before I found Glide dental floss I was less than diligent about this. Regular dental floss either broke, shredded (and stayed betwen my teeth) or hurt my fingers when I wrapped it around them.
A new brand of dental floss is out that takes care of all of these problems. It's called Glide Floss. It is more expensive than other floss, but I use less of it when I floss, so the cost is not much extra.
Dental floss seems like a small thing. But life is full of the small things. Glide is so far above other flosses that I think, once you try it, you won't go back to your old brand. Excellent.
