Are antibiotics routinely indicated for asymptomatic necrotic teeth?

• A. Only if patient requests
• B. Yes, always
• C. No; not routinely
• D. Only in pediatric patients

Answer: (C)

Antibiotics are not routinely indicated for asymptomatic necrotic teeth because the infection is localized and can be managed effectively with proper local treatment, not systemic drugs. The key is addressing the source of infection through thorough cleaning, shaping, and obturation of the root canal system (and drainage if needed). Antibiotics might be appropriate only if there are signs of systemic involvement or spreading infection, such as facial swelling, fever, or immunocompromised status. Overuse of antibiotics carries risks like adverse effects and antibiotic resistance and does not replace the need for definitive endodontic therapy. So, for asymptomatic necrotic teeth, there isn’t a routine indication for antibiotics. The other options don’t fit because treatment isn’t driven by patient request, they aren’t always needed, and age alone doesn’t determine whether antibiotics are appropriate.
