Tooth most likely to not erupt due to overcrowding

# Which of the following teeth is most likely to NOT erupt into the arch due to overcrowding?
A. Canine
B. Central incisor
C. Lateral incisor
D. 2nd premolar
E. 1st premolar

The correct answer is A. Canine.

Canines are the anterior teeth that are most
likely to be unable to erupt within a crowded dentition because the canine erupts after the incisors and premolars have already erupted.

Tooth crowding may occur in patients with
teeth that are too wide mesiodistally or if
their dental arch is too small to
accommodate all the erupted teeth.

Tooth crowding carries a genetic predisposition because it is often a matter of tooth size vs arch size.
