Best I've found so far.
As Dental Hygienist of 30+ years my favorite floss of all time is Oral-B Ultra Floss. It is an excellent oral hygiene product so of course, they stopped making it. In my search for a replacement, I settled on two contenders: Dr. Tung's, and Cocofloss. As near as I can tell both products are essentially the same except Cocofloss is maybe a few hundredths of an inch thinner and would be less aggravating for people with really tight teeth. On the other hand, it is about twice as expensive as Dr. Tung's so being a confirmed cheapskate you gotta know which one I went with. Dr. Tung's is a very lightly waxed multi-filament weave that slides nicely between the teeth and splays out under the gum line to remove the schmutz. I have not been able to get it to shred between my teeth yet, which was a welcome surprise. I guess I would recommend you pick up a spool of each of these products and evaluate which one works best for you based on performance and price.
