health benefits tea teeth
Tea for Teeth. In 2010, Japanese researchers reported at least one cup of green tea per day was associated with significantly decreased odds for tooth loss. Other studies have suggested tea may lower the pH of the tooth surface, suppressing the growth of periodontal bacteria. A more likely reason for teaâs anti-cariogenic effect is its fluoride content. Tea usually is brewed with fluoridated water and the tea plant naturally accumulates fluoride from the soil.
