What does unerupted mean?
A present tooth has not emerged in the expected developmental course.
← All explanationsUnerupted or impacted tooth
Why can a tooth remain inside the jaw?
An unerupted tooth may remain in bone or beneath the gum beyond the expected developmental stage. Lack of space, an unusual position or another obstruction can be involved. Not every tooth that appears late is pathologically impacted.

Present but not visible
A gap may hide a tooth still inside the jaw, or a tooth may never have formed. Examination and imaging when needed distinguish the possibilities.
Consider position and neighbours
Space, eruption direction and proximity to neighbouring roots matter. A displaced tooth can affect adjacent structures, but does not automatically need removal.
Plan individually
Monitoring, space creation, surgical exposure with orthodontic alignment or removal may be options. Planning can involve more than one dental specialty.
At a glance
How is it assessed?
By developmental comparison, examination and targeted imaging where needed.
What treatment is required?
This depends on tooth type, position, risks and options for retaining it.

Often confused
Unerupted or congenitally absent?
An unerupted tooth is present but has not emerged. With hypodontia, one or more teeth never formed. Looking at the gap alone cannot distinguish them.
Quick answers
Does this only affect wisdom teeth?
No. Other teeth, such as upper canines, may also fail to erupt normally. The implications and treatment depend on tooth type and position.
Must an impacted tooth be removed?
Not in every case. Symptoms, disease, neighbouring teeth, age and the prospects for alignment are weighed together.
When should a missing tooth be assessed?
If eruption differs markedly from the other side, a baby tooth stays unusually long or symptoms arise. Normal developmental variation is taken into account.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Has the missing tooth formed, where is it positioned, and would orthodontic or surgical assessment help?
Symptoms, examination findings and personal wishes form the basis of individual treatment planning.
An unusual eruption pattern can be assessed early.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Failure of eruption
- A tooth not emerging as expected during development.
- Ectopic position
- An unusual position or direction of a tooth within the jaw.
- Surgical exposure
- Making a tooth crown accessible, sometimes to allow orthodontic alignment.
Know the difference
Failure to erupt and an ectopic position describe different aspects. A tooth can show both; the term alone does not dictate treatment.
