That's what's great about the Braun Interclean -- it's a tiny revolving flosser that doesn't require threading. It gets down into the spaces between the base of each tooth better than floss. My, now I sound like a Braun commercial. There are other brands -- Water Pic makes one for about $40.00. I have the Braun toothbrush but when it gives out, I'm going back to an ultra-sonic.
I don't doubt your aptitude in flossing, Roberta, but be prepared for being ribbed about your disunineptitude (sic) for inventing words.
I don't watch enough TV that has commercials -- watching HBO's "Carnivale" last evening was a pleasure with no interruptions. When I do, I find some of the commercials are entertaining but it doesn't mean I will buy their product. I often find that unadvertised products are better and often cheaper because they don't spend billions on advertising.
