If I could leap into the air and click my heels (I can't manage it actually), I'd do it in response to this news.
Decades of dentist-induced guilt dissolved! I've never been able or willing to sustain a flossing habit, having the sort of crowded teeth that cut the nylon strands into a useless frizzle.
Apparently there is no rigorous scientific evidence to support flossing -- it's just a practice dentists endorse (and toiletry companies profit from) because of long customary usage. It probably does no harm, but it also does no proven good for our teeth.
For those of us who grew up before dental care was made somewhat less painful, and who may have had irregular dental care since somehow our mouths aren't deemed worthy of insurance in our "health system," everything about "going to the dentist" evokes anxiety shading into horror. Not having to feel guilty about flunking flossing might help just a little.
I bet they'll keep saying I should do it though. For dental workers, that's just a habit.
The article doesn't say whether there is any scientific basis for using brush picks to clean between teeth. Probably not. But at least I can made them work without trapping a mouthful of shredded thread.
