Microdontia is a condition in which teeth appear smaller than normal. In the generalized form, all teeth are involved. In the localized form, only a few teeth are involved. The most common teeth affected are the upper lateral incisors and third molars. The affected teeth may be of normal or abnormal morphology.

There are 3 types of microdontia:

  • True generalized microdontia
  • Relative generalized microdontia
  • Microdontia involving a single tooth[1]

True Generalized Microdontia[edit]

All the teeth are smaller in size, mainly reported in the case of pituitary dwarfism. All the teeth are well formed and small.

Relative Generalized Microdontia[edit]

There is an illusion of true microdontia.

Microdontia involving a single tooth[edit]

Commonly affects the maxillary teeth, mainly the lateral incisors and third molars. The lateral incisors become peg shaped.
