Which statement about avulsed primary teeth is true?

• A. Tetracycline is not recommended in children under 12 with avulsed teeth.
• B. Primary teeth should be reimplanted.
• C. Reimplantation of primary teeth is not recommended.
• D. Teeth should be kept at room temperature.

Answer: (C)

When a primary tooth is completely knocked out, replantation is not recommended. The developing permanent tooth beneath the primary tooth is delicately forming in the jaw, and putting a primary tooth back in can risk damage to that tooth germ, potentially causing eruption problems, misalignment, or enamel and root abnormalities in the permanent successor. The root structure of a primary tooth and the healing potential of its periodontal ligament are not favorable for successful reattachment, and attempting to replant can lead to complications such as ankylosis that can affect growth of the jaw. Therefore the best management focuses on cleaning the area, stopping any bleeding, and arranging prompt dental follow-up, rather than replanting the avulsed primary tooth. If the tooth is found outside the mouth, keep it clean and bring it to the dental visit for evaluation, while addressing the emergency basics as needed.
