Abstract:
This paper presents two cases in which supplemental premolars were an incidental finding. Although anomalies of tooth number and form are quite common, both cases demonstrate late forming supernumeraries with one case illustrating their development in a more unusual site. It is not routine practice to screen for late development of teeth during orthodontic treatment. Therefore the possibility of their interference with occlusal development or orthodontic mechanics such as space closure, should always be kept in mind.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
