Patient: Isabella Rivera, a 32-year-old female, presents to the emergency department with four days of progressively worsening left lower tooth pain. She describes the pain as severe, constant, deep, and throbbing, initially triggered by cold but now occurring spontaneously and lasting for extended periods. The pain frequently wakes her from sleep and worsens with chewing. She reports minimal relief with over-the-counter medications. She denies fever, facial swelling, drainage, difficulty swallowing, or breathing issues. She appears uncomfortable and reports significant difficulty sleeping due to pain.

Goals: Your assignment is to interview a patient presenting with severe dental pain. Gather relevant information to determine the underlying cause, assess severity, and differentiate between inflammatory and infectious conditions. Maintain clear, empathetic communication throughout the interaction.

Educational focus: This case focuses on recognizing irreversible pulpitis and distinguishing it from reversible pulpitis and dental infections. Emphasis is placed on identifying key pain characteristics, understanding why antibiotics are not indicated, and providing appropriate pain management and referral guidance.

Scope: This patient can respond to questions across multiple domains, including chief complaint, history of present illness, medical history, family history, and social history. The case supports development of clinical reasoning and triage decision-making in dental pain scenarios.
