Tea is good for oral health. Recent studies by researchers at the University of Chicago have shown that the polyphenol in black tea deactivates the enzymes of oral bacteria, causing them to be inactive, and as a result, dental plaques are deactivated and tooth decay is prevented. Of course, in this review, black tea was used as a mouthwash, but drinking tea also helps to remove plaques.
Due to having a significant amount of tannin and fluoride, tea prevents decay, decay and cavities in the teeth. Studies by Japanese scientists have shown that children who drink tea are less prone to tooth decay and worm infestation. The Japanese have recently developed and marketed a type of toothpaste that is based on tannin.
Perhaps the reason for this misconception is the sugar and sweeteners that are consumed with tea and cause tooth decay. It is better to drink tea without sugar, or use sugar or sugar dissolved in tea, and to prevent tooth decay and discoloration, wash your mouth and teeth with water after drinking tea.
2) The effect of tea on the heart
Drinking tea is recommended for heart patients. Tea prevents dangerous blood clots that lead to heart attacks and strokes. Studies show that some tea drinkers have lower blood lipid levels and blood pressure than others. After conducting extensive research projects on patients, Russian scientists have found that tea has powerful effects to delay the progression of arteriosclerosis, strengthen capillaries, thin the blood, and reduce blood pressure.
Other research also confirms the beneficial effects of tea in supporting the cardiovascular system. In the late 1960s, scientists from the Lawrence Livemore Laboratory at the University of California measured atherosclerosis in the arteries of about 300 Caucasians who drank coffee and 100 Chinese people who drank tea. The results of this 14-year study showed that the group that drank tea had a third less cardiovascular damage than the group that consumed coffee.
Also, tea, especially not very colored tea, prevents the formation of atheroma (formation of vascular blockage plaques) in the aorta. The result of an experiment in which a number of rabbits ate tea as a drink showed that these rabbits who ate plain water suffered less discomfort and aorta damage. Japanese research in the 1980s shows that tea reduces blood cholesterol and triglycerides.

Also, several studies have been conducted in connection with the positive effect of tea in the prevention of lung and uterus cancer.
Japanese researchers believe that tea ranks first among natural anti-cancer substances. Some first-rate scientists of the National Institute of Genetics of Japan announced in a report that there is a type of tannin in Japanese green tea that has anti-cell mutation properties and is therefore an anti-cancer agent.
Among the hundreds of types of plants that Japanese researchers examined in a wide study program in order to find the best and most effective plant against cell mutation, green tea has been the most effective substance in the laboratory. Studies have shown that people who often drink green tea are less likely to develop stomach cancer than others.
