A 5-year-old presents with a mesiodens. Teeth E and F are mobile. What is the most appropriate management?

Correct answer: B. Extract E and F and remove the mesiodens

• A. Incorrect. Retaining a mesiodens is the specific thing that obstructs permanent incisor eruption.
• B. Per the recall source. E and F are exfoliating physiologically, and the mesiodens should be removed to prevent delayed eruption, ectopic eruption or midline diastema of the permanent incisors.
• C. Incorrect on this reading. Mobile primary teeth that are exfoliating are removed at the same appointment rather than left behind.
• D. Incorrect. Pure observation risks impaction or displacement of the permanent centrals.

Note: ⚠️ Timing of mesiodens removal is genuinely debated. Many pediatric texts favour early removal once diagnosed (to avoid eruption disturbance); others favour deferring until root formation of the permanent incisors is well advanced to reduce surgical risk to the developing teeth. Discuss as a group.
