What does the term "gingivitis" refer to?

The term "gingivitis" specifically refers to the inflammation of the gums, which is a common condition that can occur due to factors such as plaque buildup, poor oral hygiene, or certain medical conditions. When the gums become inflamed, they may appear red, swollen, and bleed easily during brushing or flossing. This condition is often an early stage of gum disease, which can progress to more severe forms if left untreated. Understanding this helps emphasize the importance of maintaining good oral hygiene to prevent gingivitis and related dental issues. The other options describe different dental conditions or procedures that are not related to the inflammation of the gums.
