Surprisingly Little Evidence for the Accepted Wisdom About Teeth – The New York Times
Turns out there is little evidence for many dental practices:
A systematic review in 2011 concluded that, in adults, toothbrushing with flossing versus toothbrushing alone most likely reduced gingivitis, or inflammation of the gums. But there was really weak evidence that it reduced plaque in the short term. There was no evidence that it reduced cavities. That’s pretty much what we learned recently.
