Drinking more brown sugar water is beneficial to health preservation.
(3) alum brushing method
grind 50g of alum into powder. Brush your teeth with a toothbrush every time, twice a day, to remove yellow tartar.
(4) squid bone brushing method
take 50g squid bone, grind it into fine powder, mix it into toothpaste and brush your teeth twice a day to remove black tartar. The above are simple methods to remove tartar. As long as the teeth are free of tartar, it is impossible to form calculus. Once the calculus is formed, the effect of the above method is minimal. Only ask the stomatologist to scrape it with instruments, which is a time-consuming and incomplete method that can also hurt the teeth. The effect of removing the calculus with an ultrasonic dental cleaner is better.
