Which dental specialty focuses on the diagnosis and treatment of diseases affecting the supporting structures of the teeth?

The specialty that focuses on the diagnosis and treatment of diseases affecting the supporting structures of the teeth is periodontics. This field encompasses the study of periodontal diseases, which include conditions that impact the gums, bone, and other supporting tissues around the teeth. Periodontists are trained to manage various treatment modalities, including scaling, root planing, and surgical interventions, aimed at maintaining or restoring health to these supporting structures. The emphasis on prevention, diagnosis, and treatment of conditions such as gum disease underscores the essential role that periodontics plays in overall dental health.

In contrast, endodontics specializes in the treatment of dental pulp and root canal therapy, orthodontics deals with the alignment of teeth and jaws, and pediatric dentistry focuses on the dental care of children. Each of these specialties addresses different aspects of oral health, making periodontics unique in its focus on the support system of teeth.
