Question: 1 / 400

What is the recommended action for an avulsed (knocked-out) tooth?

Store it in milk

Re-implant promptly

Re-implanting an avulsed tooth promptly is crucial because it increases the chances of successful reintegration into the socket and helps preserve the vitality of the tooth. When a tooth is knocked out, the periodontal ligament cells, which are essential for the tooth's attachment to the jawbone, are still alive for a limited time; thus, immediate re-implantation is ideal. Handling the tooth by the crown (the visible part) rather than the root is important to avoid damaging these sensitive cells.

While storing the tooth in milk can help preserve it if immediate re-implantation isn't possible, re-implanting it as soon as feasible is the best option. Other methods, such as allowing the tooth to dry out or brushing it clean before storage, can damage the tooth and reduce the chances of successful reintegration.
