Which of the following is a common sign of periodontal disease?

A common sign of periodontal disease is bleeding gums. This condition arises due to inflammation and infection of the tissues surrounding the teeth, which can lead to the breakdown of the supporting structures of the teeth. When the gums become irritated and inflamed, they are more prone to bleeding, especially during brushing or flossing. This symptom is often one of the earliest signs of periodontal disease and can indicate underlying issues that need to be addressed, such as plaque buildup or gum inflammation.

Understanding the significance of bleeding gums is crucial, as it can prompt individuals to seek the necessary dental care to prevent further progression of periodontal disease, which can lead to tooth loss if left untreated.
