Oral strains of bacteria from the mouth composed of a variety. Wide range of bacteria in the mouth, it can be said, how many kinds of bacteria in the air, the mouth there are many kinds of bacteria. In addition, oral bacteria can also be derived from water and food.
Some experts have made a study of oral bacteria that are pathogenic for at least a dozen. Under normal circumstances, most bacteria are not pathogenic. Only when people suffering from the disease, caused by the body defenses are weakened, or because the risk of certain infectious diseases take a lot of antibiotics, usually do not have the pathogenic bacteria, can cause oral disease, medically known as the flora of this situation disorders. Such as fungal stomatitis is dental instruments a disease caused by flora. Therefore, the pathogenic bacteria and non-pathogenic bacteria is relative. Definitely not non-pathogenic bacteria are not pathogenic.
Another scholar made a bacteriological study of saliva and found that the bacteria per milliliter of saliva in the number of up to 1.5 million. However, the number of bacteria in saliva is not constant. Also made such a study, the number of oral bacteria that people have Variability Prevention stomatitis several changes in the day, the highest number of bacteria in three meals a day before, the lowest in the teeth after. It suffices to show that maintaining good oral hygiene, teeth brushed, especially in the prevention of oral diseases is important.
