When handling a knocked-out tooth from a child, how should the tooth be picked up?

When handling a knocked-out tooth, it is crucial to pick it up by the root rather than by any other part of the tooth. Grasping the tooth by the root helps preserve the periodontal ligament, which is essential for the reattachment of the tooth if it is reimplanted. The periodontal ligament is a delicate tissue that can be damaged if the tooth is handled improperly.

When you pick up a tooth by the root, you minimize the risk of damaging this important structure and enhance the possibilities of successful re-implantation. In contrast, handling a tooth by the edge, chewing surface, or the top can lead to contamination or damage, severely affecting the tooth's viability for reattachment. Therefore, it is always emphasized in emergency dental situations to handle the tooth with care and by the root if possible. This practice is vital for encouraging the best possible outcome in cases of dental avulsion.
