Breaking news: black coffee could help keep your teeth clean

smileIf you’re a true coffee aficionado and take your coffee as seriously as we do, chances are you like your favourite drink black, strong and sugarless, and in addition to tasting great new research has shown that drinking your coffee like this could actually be helping to clean your teeth.

Research by Rio de Janeiro’s Federal University and reported by the Telegraph newspaper on the 11th June 2014 has found that coffee with high caffeine content, such as espresso blends or blends high in robusta coffee beans, can destroy bacteria which cause dental plaque. According to the study, the process only works if you drink your coffee black and unsweetened as milk and sugar will be counterproductive and destroy the helpful effects.

Andrea Antonio, lead researcher at the university, said: “Dental plaque is a classic complex biofilm and it’s the main culprit in tooth decay and gum disease. We are always looking for natural compounds – food and drink, even – that can have a positive impact on dental health.”

The robusta coffee beans contain polyphenols, a chemical which destroys bacteria on teeth using the process of lysis, which disintegrates the structure of the bacteria cells.

Scientists now hope to isolate and extract the polyphenols and add them to new oral hygiene products such as toothpaste and mouthwash to make them more efficient. This would mean that children and non-coffee drinkers would be able to benefit as well.
