What is the most important factor in managing tooth avulsion?

• A. The avulsed tooth must be replanted immediately if possible, ideally within 5 minutes
• B. The tooth should be left out to dry for 20 minutes
• C. The tooth should be kept in dry gauze during transport
• D. The tooth should be transported to the dentist without replantation

Answer: (A)

Immediate replantation of an avulsed tooth, when feasible, gives it the best chance of survival and proper long-term function. The key is preserving the periodontal ligament cells on the root; if the tooth dries out or is not placed back in the socket promptly, those cells die, increasing the risk of failure, ankylosis, and root resorption. Letting the tooth sit dry or transporting it without attempting replantation misses the critical window where reintegration is most likely. If immediate replantation isn’t possible, keep the tooth moist (for example, in milk or saline) and seek dental care quickly to maximize the outcome.
