3 cups of black tea per day can prevent tooth decay
Drinking tea often has many benefits. A recent study in the UK found that drinking at least 3 cups of black tea a day keeps the mouth clean and reduces the risk of tooth decay.
Dr. Kelly Luxton, President of the British Nutrition Association, and his colleagues conducted a combing analysis of a number of related studies on tea and health. They found that black tea can fight against two types of bacteria that cause dental caries and dental diseases: Streptococcus And lactic acid bacteria. The most effective “dose” is 3 to 4 cups of black tea per day. Scientists have found that even if black tea is added with sugar, it still has anti-caries effect.
The study found that green tea has a similar effect, and green tea also helps to neutralize sulfides in the mouth and thus prevent bad breath. In addition, a large body of evidence from a number of studies suggests that drinking tea can prevent the risk of tooth loss.
According to Dr. Luxton’s analysis, oral bacteria act on carbohydrates, which are prone to damage to the enamel’s acidic substances, which can lead to damage to the tooth tissue, formation of dental caries and even loss of teeth. Black tea and green tea can reduce oral inflammation, prevent bacteria from sticking to the teeth, and inhibit oral bacteria growth. The tea contains various anti-oxidant components such as flavonoids and a tannin-like substance catechol having an antibacterial action.
