The mouth is considered the dirtiest place in the human body. It carries the largest amount of bacteria and germs

Many people will assume that the anus is the dirtiest place on the body due to its contact with fecal matter. The mouth comes into contact with more germs and bacteria than the rectal area. In fact, scientists at Harvard School of Dental Medicine have discovered more than 615 different types of bacteria that can live in the mouth, tongue and throat.

Germs and bacteria in the mouth can contribute to illnesses as mild as the common cold and as severe as heart disease. Dr. Sally Cram, a dentist and spokeswoman for the American Dental Association, has confirmed that numerous studies point to a connection between periodontal disease and heart attacks.
