Which statement is correct regarding flare-ups?

• A. Always warn your patient of a flare-up.
• B. Do not discuss flare-ups.
• C. Flare-ups are impossible.
• D. Flare-ups only occur in necrotic teeth.

Answer: (A)

Flare-ups are a potential post-treatment complication where pain, swelling, or a need for additional care can occur after endodontic procedures. Because patient experiences vary and outcomes can differ even with careful technique, it’s important to prepare patients by discussing this possibility upfront. Warning patients about flare-ups helps set realistic expectations, reduces anxiety if symptoms arise, guides them on when to seek help, and supports informed consent and ethical care. Flare-ups can occur in different clinical situations and are not limited to a specific tooth type or condition, so keeping patients informed is the best practice.
