Black coffee helps to clean your teeth

Rio De Janeiro - A cup of strong coffee helps to kick start many people's days. Scientists have found that it may have the added benefit - cleaning your teeth.
A new study has found that a compound in coffee breaks down the bacteria associated with tooth decay, MSN reports. There is just one catch, though, the coffee needs to be black to be effective. The scientists behind the study have pointed out that the effect would be cancelled out by milk and sugar.
Research by Rio de Janeiro’s Federal University, led by Andrea Antonio, examined the impact of an extract of Coffea canephora – known as robusta – on milk teeth. Robusta is a coffee bean grown in Brazil and Vietnam. It has a higher caffeine level than the other main coffee variety, Arabica.
The process of teeth cleansing works by polyphenols, a chemical contained in the beans, destroying bacteria on teeth by bursting it open in a process known as lyse. As a possible future application, the chemical could be extracted and added to toothpastes or mouthwash to help reduce plaque. The findings will be published in the journal of Applied Microbiology.
In a related story, Digital Journal recently reported that food scientists have suggested that a daily cup of coffee can aid the prevention of deteriorating eyesight and possible blindness from retinal degeneration, due to glaucoma, aging and diabetes.
