Unerupted Tooth

An unerupted tooth is a tooth that remains below the gum line and has not broken through into the mouth by the age it would normally be expected to do so. This can occur because the tooth is still developing, there is not enough space in the dental arch, it is blocked by another tooth or bone, or there are other developmental issues; an unerupted tooth is distinct from an impacted tooth, which is specifically blocked from erupting.

Diagnosis typically involves a clinical examination and dental X-rays to assess position and development. Management depends on the cause and may include watchful monitoring if the tooth is likely to erupt, orthodontic methods to help guide the tooth into place, surgical exposure or removal if it is unlikely to erupt or is causing problems, and later restorative options such as implants or bridges if the tooth cannot be retained; timely assessment helps reduce risks such as misalignment, cyst formation, or damage to adjacent teeth.
