WTN- Sounds amazing but true, Researchers found that an average person has 20 to 100 billion bacteria in their mouth at any given time which is quietly equal to the entire human population on earth.

Several studies conducted on it and researchers have identified over 700 different kinds of bacteria species that dwell in human mouths.

You need not to worry because most of these bacteria are harmless while some of them are harmful. They also reproduce every five hours. If you go 24 hours without brushing, those 20 billion become 100 billion!”- Window To News
