Mesiodens are usually conical in shape and may be
paired. In children, 85% of anterior supernumeraries are
unerupted, and 65% interfere with the normal eruption
of the maxillary permanent incisors.2 The 15% that do
erupt can do so at any age, but eruption usually occurs
between the ages of 3 and 7. The mesiodens may emerge
in the palate or may resorb the roots of the primary central
incisors and erupt in their place.
