When managing a tooth avulsion, why should you handle the tooth by the crown?

• A. To protect the periodontal ligament and vascular structures on the root.
• B. To allow easy grip.
• C. To prevent staining.
• D. To make it fit back more easily.

Answer: (A)

The key idea is protecting the periodontal ligament on the root surface. Grasping the tooth by the crown keeps your hands away from the root where the delicate PDL cells and surrounding blood vessels live, so you don’t crush or detach them. Preserving these cells is crucial for reattachment and healing after reimplantation, which directly affects the tooth’s prognosis. The crown is the sturdier part to hold, reducing trauma to the root surface, whereas touching or scrubbing the root can damage the PDL. Staining or simply making it fit back more easily aren’t the main factors here, and any slight ease of gripping the crown doesn’t replace the importance of protecting the root surface and its healing tissues.
