How many times a day should I brush my teeth?

Since childhood, we have been taught to brush our teeth every day, but how many times should we brush our teeth is a matter of opinion. Some people think that brushing once in the morning and once in the evening is enough, while others think that you should brush once after eating. So how often should we brush our teeth scientifically? According to the dentist's recommendation, we should brush our teeth at least twice a day. Eating during the day will stimulate the secretion of saliva, which has a self-cleaning effect. However, saliva secretion decreases during sleep, so brushing at night is especially important to prevent bacteria from multiplying at night and causing damage to the teeth.

Some people may ask, why can't we brush after every meal? In fact, after eating, our oral environment will become acidic, and brushing at this time may cause damage to the enamel of the teeth. So, if you feel uncomfortable in your mouth, you can choose to rinse your mouth with water or wait for half an hour before brushing. So, the frequency of brushing is not the better, the key is to brush your teeth scientifically!
