What is the common consequence of untreated periodontal disease?

The common consequence of untreated periodontal disease is tooth mobility and loss. Periodontal disease is a chronic inflammatory condition affecting the supporting structures of the teeth, including the gums, bone, and periodontal ligament. When this condition is not addressed, it leads to the breakdown of these supportive structures. As the periodontal tissues deteriorate, teeth can become loose due to the loss of bone and connective tissue support.

Over time, if the periodontal disease progresses unchecked, it can result in tooth loss. The inflammation and infection can also create pockets between the teeth and gums, exacerbating the issue further. This link between untreated periodontal disease and tooth mobility illustrates the importance of early diagnosis and treatment to maintain dental health.

The other options do not accurately reflect the outcomes related to untreated periodontal disease, as they suggest improvements or unrelated changes that do not occur as a result of the condition.
