I know that a lot has changed in terms of technology and such since I wore braces, but these Floss Threaders still seem to be a staple! There is no way I could have had my mouth transformed from a crooked mess to a perfect smile without diligently brushing and flossing every day when I had my braces, and there was no way I could have flossed with braces without the floss threaders! I used them every night, in between each tooth and out under the wire of my braces with the non-waxed floss - and I mean EVERY NIGHT! My orthodontist told me if I did everything that he said that I could get my braces taken off within two years and so that's what I did... and in two years my braces were off! At each of my monthly Orthodontist appointments I was always endlessly praised by everyone in the office, they always said they knew I was flossing everyday because my oral health was great and it showed. One tip: floss threaders are fairly durable and can be used more than once - don't throw these away after just one use (if it's still in good condition, that is)!
