Brits could improve their oral health through drinking green tea. 
Research carried out in Japan by Yasushi Koyama from Tohoku University Graduate School of Medicine has shown a link between drinking green tea and improved oral health.
The report showed a 23 per cent reduction in the risk of decay in those people who drank a cup of green tea every day in comparison to those that did not.
It concluded that catechins found in the tea help prevent the build-up of bacteria that are linked to the risk of periodontal disease and decay and as such, regularly drinking the beverage can help improve overall dental health.
Elsewhere, C Health recently reported many people falsely assume that stained teeth come about as a result of poor oral health and this is not always the case.
Indeed, the other factors which can increase the likelihood of stains include smoking, bad diets, drinking large amounts of coffee or red wine.
