Ardent coffee lovers, have a reason to smile! Recent
studies have successfully managed to show the noble side to COFFEE. Researchers
prove that apart from giving gruesome stains on teeth, coffee can be an
effective anti-plaque agent.
According to the study conducted at The Federal
University of Rio De Jenero, Brazil, caffeine rich varieties like Robusta
(Coffea Canephora), grown in Brazil and Vietnam, managed to inhibit plaque
formation and was bactericidal.
The Action......Scientists cultivated a bio-film on the milk tooth of
children (post exfoliation) with the help of bacteria in the saliva. When these bio-films were exposed to extracts of Robusta bean, it disintegrated and caused
the rupture of bacterial cell wall. The reason for this kind of rupture is
directed to polyphenols, found commonly in coffee.
Polyphenols are secondary metabolites of plants,
involved against UV radiation and aggression by pathogens. They are
anti-oxidants, whose phenolic group, easily receive an electron to form stable
phenoxyl radicals, hence disrupting chain oxidation reaction, leading to lysis
of cell.

| Coffee tastes better now!! |
This phenomenon is associated with high caffeine
varieties only, and is negated by the addition of milk and sugar to coffee. 1
glass of coffee = 100 mg of polyphenols, sufficient to combat plaque forming
bacteria.
Attempts are now being made to harness these coffee extracts into
toothpastes and mouthwashes, in order to get rid of staining caused by constant
consumption of coffee and for it to benefit non-coffee drinkers too.
So, even though coffee has a benevolent side, it
still stains teeth and should be consumed in moderation. Don’t forget! Brush,
twice daily and get rid of those stains to enjoy the goodness of COFFEE.
