"In addition to boring, can't lack of tea, but it hurts. I have a way to rinse my mouth with strong tea every time I eat. When you are bored, you don't know your spleen and stomach. The meat is between the teeth, so it shrinks and you are too lazy to pick holes, but if the teeth are dense. Both middle and low grade teas are used, while high grade teas are not commonly used. There's no harm in drinking for several days. This is very reasonable. "

Su Shi's regimen inspires people that gargling with strong tea soaked in the mouth after every meal is not only beneficial to oral hygiene, but also can prevent diseases and strengthen teeth.

Why do you often drink tea or rinse your mouth with strong tea to prevent diseases and strengthen your teeth? This is because strong tea contains more fluoride and caffeine. Fluoride ion has the function of preventing caries and strengthening bones. Modern medical research also shows that if everyone drinks 10g tea every day, dental caries can be prevented.
