Dental Floss May Have No Medical Benefits, Says AP Report (gizmodo.com) 257
Joe_NoOne quotes a report from Gizmodo: Flossing may not yield the protective benefits we've been told to expect. Since 1979, the federal government in the U.S. has recommended daily flossing, but by law these dietary guidelines, which are updated every five years, have to be supported by scientific evidence. Surprisingly -- and without any notice -- the federal government dropped flossing from its dietary guidelines this year, telling the Associated Press that "the government acknowledged the effectiveness of flossing had never been researched, as required." AP national writer Jeff Donn reports: "The two leading professional groups -- the American Dental Association and the American Academy of Periodontology, for specialists in gum disease and implants -- cited other studies as proof of their claims that flossing prevents buildup of gunk known as plaque, early gum inflammation called gingivitis, and tooth decay. However, most of these studies used outdated methods or tested few people. Some lasted only two weeks, far too brief for a cavity or dental disease to develop. One tested 25 people after only a single use of floss. Such research, like the reviewed studies, focused on warning signs like bleeding and inflammation, barely dealing with gum disease or cavities. Wayne Aldredge, president of the periodontists' group, acknowledged the weak scientific evidence and the brief duration of many studies...Still, he urges his patients to floss to help avoid gum disease. 'It's like building a house and not painting two sides of it,' he said. 'Ultimately those two sides are going to rot away quicker.'"

Actually - please FFS don't. Instead eat fruit and veggies as prime nutrient sources, and use a mild soap (and 3 out of 4 days just rinse the less hairy bits). Wear (thin! high thread count!) wool inner layers when possible. Once dermal fauna adjusts, and once the last of the junk food has finished sweating out, most people don't actually smell bad at all - most people have a very very mild scent. But drink cola, eat burgers chips and put butter and cheese on everything, and scrub till skin squeaks so that dermal fauna restart from almost nothing every day, and most people smell pretty atrocious.
There's caveats - some swarthier persons have a stronger scent in particular. Sandalwood goes a long way, but a rinse before and after work seems to work well.

It's the opposite actually. If your teeth are spaced apart you need flossing less. This is why young children don't really need to floss their baby teeth.
Actually the size of the gap does not matter as long as no food can get stuck inside the gap. If food gets stuck in there for a while, it will cause problems to both your teeth and gum (and you will feel it). You could try to get the food out using any method and the method does not need to be flossing. Thus, size of gap between teeth is not the reason to need or not need to floss.
