What factors influence the composition of the oral microbiome?

The oral microbiome's composition is influenced by various daily habits and environmental factors. Activities such as breathing, kissing, and swallowing can significantly impact the types of bacteria present in the mouth. Additionally, extreme modifications in diet, such as processed versus whole food consumption, can also lead to substantial changes in oral microbiome health.

• Kissing helps in sharing bacteria; studies suggest over 11 kisses a day may create a microbiome similarity between partners.
• The air quality a person is exposed to can alter the bacteria environment in the mouth.
• Regular eating and drinking habits introduce new bacteria into the mouth affecting overall oral health.

These factors show that lifestyle choices and environmental conditions play vital roles in maintaining a balanced oral microbiome, which in turn can influence systemic health.
