• A. Orthodontists
• B. Dentists
• C. Prosthodontists
• D. Periodontists

Answer: (B)

Diagnosing and treating problems with teeth and mouth tissues is the role of a dentist. They perform exams, take X-rays, diagnose cavities, infections, gum disease, and other oral conditions, and provide treatment or referrals as needed to maintain or restore oral health.

Specialists like orthodontists focus on aligning teeth and correcting bite issues, using braces or aligners as their main tool. Prosthodontists concentrate on replacing or restoring missing teeth with crowns, bridges, dentures, or implants. Periodontists specialize in diseases of the gums and supporting structures, performing procedures to treat and preserve those tissues. Because the scenario describes a practitioner who handles problems with teeth and mouth tissues in a broad sense, the best fit is the dentist.
