Which condition refers to inflammation of the tissues surrounding the teeth, potentially involving the gums and bones?

• A. Gingivitis
• B. Halitosis
• C. Dysphagia
• D. Periodontal disease

Answer: (D)

Inflammation of the tissues surrounding the teeth refers to the body's inflammatory response in the structures that support teeth, not just the gums. The gums (gingiva) are part of this supporting system, but the entire set includes the periodontal ligament, cementum, and the alveolar bone. When the inflammation stays limited to the gums, the condition is gingivitis, which is typically reversible with improved oral hygiene. If the infection involves the supporting tissues beyond the gums, it progresses to periodontal disease, which can lead to pocket formation, gum recession, and bone loss. This broader involvement of the gums plus bone fits the description of periodontal disease, making it the best answer. Bad breath (halitosis) and difficulty swallowing (dysphagia) are not about inflammation of the tooth-supporting tissues in the same way.
