What are the main types of bacteria in human's mouth?
There are a lot of them.


Examples:


Staphylococcus epidermidis


Streptococcus mitis


Streptococcus salivarius


Streptococcus mutans


Lactobacillus sp.

Reply:The more than 100 species of bacteria, and hundreds of species of fungi, protozoa, and viruses that have taken up residence in our mouths is difficult to fathom. Microbiologists estimate that, in addition to these known species, there are up to 500 other living, breathing organisms inhabiting our mouths, although only 50 have been identified and named. The sheer number of these creatures is astronomical, considering the fact that our mouths contain more bacteria than the entire world's population, and the fact that our bodies house approximately one trillion bacteria.





The only harmful species of bacteria inhabiting our mouths is Streptococcus mutants, the cavity causing bacteria. Microbiologists believe that initially, this bacteria was our friend, and played a useful role in our mouths, just as the other species of bacteria do. As man progressed down the evolutionary timeline and began refining raw sugar, Streptococcus mutants became the enemy. This species thrives upon refined sugar and, as a part of its digestive process, converts sugar into acid.





All mouths have "natural flora" bacteria. Some examples of normal flora in your mouth are Streptococcus salivarious, Streptococcus mutans, and Actinomyces. Different types of bacteria can grow in numerous ways. Some require oxygen (aerobic) and some will not grow when oxygen is present (anaerobic). The bacterium Streptococcus salivarious does


require oxygen to grow and it receives it nutriets from many of the things we eat everyday. A example of an bacteria that is anaerobic is Actinomyces and it probably hangs out between the teeth where oxygen has a much harder time getting to.

Reply:The mouth contains a wide variety of bacteria, but only a few specific species of bacteria are believed to cause dental caries: Streptococcus mutans and Lactobacilli, Streptococcus salivarius among them.[5][7] Particularly for root caries, the most closely associated bacteria frequently identified are Lactobacillus acidophilus, Actinomyces viscosus, Nocardia spp., and Streptococcus mutans. Bacteria collect around the teeth and gums in a sticky, creamy-coloured mass called plaque, which serves as a biofilm. Some sites collect plaque more commonly than others. The grooves on the biting surfaces of molar and premolar teeth provide microscopic retention, as does the point of contact between teeth. Plaque may also collect along the gingiva. In addition, the edges of fillings or crowns can provide protection for bacteria, as can intraoral appliances such as orthodontic braces or removable partial dentures.
