Tooth transplantation is mainly divided into two types:

  • Allotransplantation (homogenous), where a tooth is transferred from one individual to a different individual of the same species. Nowadays, it is largely abandoned as the practice carries many risks including transmission of infection, such as syphilis, and histocompatibility issues. Long-term success of allotransplantation of teeth was also extremely rare, usually lasting about six years.
  • Autotransplantation (autogenous), where a tooth is transferred from one site to another in the same individual.
