The purpose of Periodontics is best described by focusing on the diagnosis and treatment of diseases affecting the supporting structures of the teeth, which include the gums, bone, and periodontal ligaments. This specialty addresses conditions such as gum disease, periodontal infections, and other issues that affect the health of the supportive tissues surrounding the teeth.

By emphasizing the management of these conditions, Periodontics aims to preserve the health of the gums and bone, which are crucial for maintaining stable and functional teeth. Treatments may involve scaling and root planning, surgical interventions, and preventive care strategies to improve or restore periodontal health, ensuring successful long-term outcomes for dental patients.

The other options reflect different aspects of dentistry. Aligning teeth and jaws pertains to Orthodontics, performing root canals is a function of Endodontics, and fabricating dental crowns and bridges falls under Prosthodontics. Each of these specialties focuses on distinct areas of dental care, underscoring the importance of Periodontics in maintaining the foundational health of the mouth.
