What is the most common bacterial infection found in the mouths of adults?

Gingivitis is the most common bacterial infection found in the mouths of adults. This condition arises from the accumulation of plaque on the teeth, which leads to inflammation of the gums. It is characterized by symptoms such as redness, swelling, and occasional bleeding during brushing or flossing.

One of the key reasons gingivitis is prevalent is due to the commonality of plaque buildup, which occurs when oral hygiene is insufficient. Many adults experience gingivitis at some point, often without severe discomfort, making it easy to overlook. Importantly, if gingivitis is left untreated, it can progress to more serious forms of periodontal disease, which can have further implications for oral and systemic health.

Recognizing gingivitis as a bacterial infection highlights the importance of maintaining good oral hygiene practices, such as regular brushing, flossing, and dental check-ups, to prevent not only gingivitis but other more advanced oral health issues.
