Coffee is good for your teeth?

 Researchers are making a new claim about coffee and your teeth. A cup of black coffee a day could keep the dentist away? According to a new study, Your teeth may not be bright white, but it could help you keep your teeth.

Scientists tested  Coffea canephora, a type of bean used a large percentage of the world’s coffee.
  The tests showed that the coffee breaks down bacteria biofilms that cause plaque, but more research is needed before a direct link can be established. Researchers warned that too much coffee can still be bad for teeth.
  Excessive coffee consumption, has it's problems tho, including staining and the acidity effects on tooth enamel, Also if you take a lot of sugar and cream in your coffee, any positive effects on your teeth are probably going to be cancelled out.
