A Cup Of Green Tea A Day Keeps The Dentists Away

Thu, 22 Apr 2010

A new study has revealed that drinking green tea may have dental health benefits.

Researchers at the Tohoku University Graduate School of Medicine in Japan found that people who drank one cup of green tea a day were more likely to keep their teeth as they get older.

The study of 25,000 Japanese men and women aged between 40 and 64 found that men who drank at least one cup of tea a day were 19 per cent less likely to have fewer than 20 teeth than those who did not drink green tea. For women, the odds were 13 per cent lower.

According to the researchers, the dental benefit of green tea is provided through antimicrobial molecules called catechins, which have been shown to kill mouth bacteria associated with tooth decay and gum disease .

However, they warned that adding sugar or sweetener to green tea may counteract the bacteriocidal effects.

Samuel Low, of the University of Florida College of Dentistry and President of the American Academy of Periodontology, revealed that regularly drinking green tea has already been proved to "possess certain health-related benefits".

He said: "Previous research has indicated that regular consumption of green tea may lead to a lower instance of periodontal disease, a leading cause of tooth loss in adults."
