Numerous genetic and environmental factors may cause abnormalities in tooth development. These may include

  • defects of structure (e.g. abnormal enamel, amelogenesis imperfecta, or abnormal dentin, dentinogenesis imperfecta or dentin dysplasia)
  • abnormal position of tooth
  • reduced size and abnormal shape of teeth (e.g. “peg-shaped” incisors, taurodontism, or short root anomaly)
  • missing of one or more teeth (hypodontia, oligodontia, tooth agenesis).
