Gargle your coffee!?

A study at the "Federal University of Rio de Janeiro" says that coffee with a caffeine can destroy some bacterias which makes dental plaque. It is more effective when you use Robusta, a kind of coffeebean including more caffeine, origins western sub-Saharan Africa. And you should be careful to use sugar and milk. They ruin the effect.

If we just drink a cup of coffee and don't brush your teeth, but our teeth is clean and healthy, I think it is very comfortable. We can just drink coffee, and no more care about teeth!! But most of case, it's not work because we drink coffee with other additivs. And I think we need to feel refreshment when drink coffee. And I think need more study how to get rid of the smell of coffee.
