The oral microbiome refers to the diverse community of microorganisms, including bacteria, viruses, fungi, and protozoa, that inhabit the mouth. These microorganisms play a crucial role in maintaining oral health by aiding in digestion, protecting against harmful pathogens, and contributing to the immune response. A balanced oral microbiome is essential for preventing dental issues such as cavities and gum disease. Changes in the oral microbiome can lead to dysbiosis, which is an imbalance that may result from factors like poor oral hygiene, diet, or certain medications. This imbalance can contribute to various health problems, including periodontal disease and even systemic conditions like cardiovascular disease. Understanding the oral microbiome is vital for developing effective strategies for oral health care.
