Which statement about watchful waiting for irreversible ectopic molars is correct?

• A. Watchful waiting is never indicated
• B. There is no potential for self-correction
• C. Two-thirds potential for self-correction
• D. Immediate extraction is always necessary

Answer: (C)

Watchful waiting rests on the idea that many irreversible ectopic molars correct their eruption path as the dentition and jaw grow, so a large portion may realign without intervention. In this scenario, about two-thirds of cases show spontaneous self-correction, meaning the molar moves toward a normal trajectory on its own over time.

This approach is used when the ectopia is mild and there’s no damage to adjacent teeth, no significant pathology, and there’s enough space for the tooth to move into a normal position. The plan involves careful observation with regular clinical exams and radiographs over several months to a year to watch for favorable change. If improvement occurs, continue monitoring; if there’s no sign of progress, or if the adjacent tooth shows resorption, decay, or other problems, or if the eruption remains markedly misaligned, then targeted intervention—such as removing a primary molar or other corrective measures—may be considered.

So this option is best because it reflects the real likelihood that spontaneous correction happens in a substantial number of cases, guiding a less invasive initial management when appropriate. The other statements are not as accurate: watchful waiting is not never indicated; there is indeed potential for self-correction; and immediate extraction is not universally required for all presentations.
