The oral microbiome is composed of several different types of bacteria that can affect how our body operates. There are over 700 different bacteria living in our mouths. These bacteria can be helpful and harmful to our bodies, but they are synergistic in a way. There are several factors such as age, diet, smoking, and oral care that affect bacterial makeup. When there 10 is a significant difference, our immune system becomes weakened and respiratory disease set in. The immune system then works to return the microbiome back to homeostasis. When this fails, the diseases become chronic. Thus, the oral microbiome be used as an environmental effects guide when looking at respiratory diseases in the future as preventative care.
