There are more bacteria in your mouth than humans on the planet

Scientists at the Harvard School of Dental Medicine have already found more than 615 different bacterial species in the human mouth, and they believe there is still more to be found. The institution's professionals also claim that the total number of microorganisms in this region of the body may exceed the number of human beings on Earth. Scary, isn't it?

Thus, the human mouth is considered a small jungle of bacteria. The humidity of the saliva and the presence of sugars and carbohydrates in the food make this space a great environment for the proliferation of microorganisms. In addition, experts believe that variation in the number of certain species may be the key to determining patients' oral health and assisting early diagnosis of oral cancer.
