In order to promote eruption and proper
alignment of adjacent teeth, it is recommended
to extract mesiodens in the early mixed dentition,
which may reduce the need for orthodontic
treatment. It might take six months to three
years for an unerupted tooth to erupt after removal
of the mesiodens [58]. Henry and Post
[63] suggested delayed extraction of the mesiodens
about the age of 10 when the apex of
the central incisor nearly forms. If treatment is
postponed after this age, more complex surgical
and orthodontic treatment may be necessary.
The type and position of the unerupted
tooth, the space available in the dental arch, in
addition to the stage of root development may
influence how long it takes for an impacted
tooth to erupt after surgical removal of the mesiodens
