Why to brush teeth?

Guys, many of you forget that you should brush your teeth in the morning and in the evening. And do you know that 40 million microbes live in the man’s mouth? However, don’t be afraid, since most of them are useful, although there are 200 thousand harmful microbes that can be killed using a toothbrush, toothpaste and special gargling solutions. While one tooth brushing provides protection against microbes for 12 hours, there are 24 hours in a day. So, please determine yourself, guys, whether it is enough to brush your teeth only once a day.
