Experiments with animal models have shown that the tooth crown structure can be regenerated using tissue engineering techniques that combine tooth bud cells and biodegradable materials, or by using embryonic tissue and adult stem cells. Moreover, tooth roots and periodontal tissues have been reconstructed by grafting dental stem cells, which leads to the recovery of tooth function, suggesting that tooth regeneration will become possible in humans in the near future. The present article reviews current research on tooth regeneration, discusses a model of tooth replacement that could be used clinically, and proposes a new tooth regeneration approach that overcomes the difficulties associated with the tooth replacement model. Tooth regeneration is an important stepping stone in the establishment of engineered organ transplantation, which is one of the ultimate goals of regenerative therapies.
