A cup of green tea a day may keep the dentist away. That's the finding of a study recently published in Preventive Medicine, which examined over 25,000 Japanese people aged 40-64. Those who drank at least one cup of tea daily had significantly lower rates of tooth loss.
Scientists suspect that antibacterial molecules called catechins may be responsible for the dental benefits of green tea, possibly reducing rates of gum disease. Green tea also has high concentration of fluoride, which can strengthen teeth and fight tooth decay.
