What are some signs of periodontal disease?

Signs of periodontal disease include red, swollen gums that bleed easily. This condition is characterized by inflammation of the gums due to bacterial infection, which leads to the swelling and bleeding observed. Healthy gums typically appear pale pink, firm, and do not bleed during brushing or flossing, which would indicate the absence of such disease. Periodontal disease can progress to more serious issues if not addressed, often leading to tooth loss and affecting overall health.

The other options describe healthy dental conditions or characteristics unrelated to periodontal disease. Healthy gums and teeth would not exhibit any of the indicators associated with periodontal disease, such as swelling or bleeding. The presence of tartar is also a concern in periodontal conditions, but shiny teeth without tartar reflects good oral hygiene rather than disease. Proper alignment of teeth does not relate to gum health or periodontal conditions. Thus, the only correct manifestation indicative of periodontal disease is characterized by the inflammation and bleeding of gums.
