Which term describes a tooth that has not erupted and remains within the jawbone?

• A. Erupted
• B. Unerupted
• C. Impacted
• D. Retained

Answer: (B)

Understanding eruption status helps describe where a tooth is in its development. A tooth that has not erupted and stays within the jawbone is described as unerupted. This simply means eruption hasn’t occurred yet, but the tooth remains in the bone rather than in the mouth. Erupted means it’s already emerged into the oral cavity. Impacted describes a tooth that cannot erupt due to an obstruction, often still within the bone or soft tissue. Retained usually refers to a tooth that should have erupted but hasn’t for some reason, such as a deciduous tooth lasting longer than expected. Therefore, unerupted is the most accurate term for a tooth that has not erupted and remains in the jawbone.
