What's the chance that our dentistry practices are optimal?
Think about it.
Many of the practices of 1980 medicine have been found ineffective or even misguided.
Remember estrogen therapy? If you're a physician of a certain age, that question should make you shudder.
But we still brush and floss much as we did in 1980?
Do you really think we got it right the first time?
Or is that we really don't do dental prevention research?
Imagine the cost if we've got it wrong.
