Although replantation of avulsed primary teeth is described as a contraindication in some books, there have been reports that patients had uneventful courses after replantation of avulsed primary teeth until eruption of the succeeding permanent teeth. We replanted an avulsed primary central incisor and followed up the patient until eruption of the succeeding permanent incisor. The patient was a boy aged 2 years and 1 month old at the initial visit. He fell from a chair and hit the maxillary incisor region. At the injury, the right primary central incisor was avulsed, and the patient came to the clinic after preserving the lost tooth in milk. Since the patient's parent strongly wished replantation of the tooth at the initial visit, we carefully explained the risk of infection after replantation, obtained the parent's consent, and replanted and splited the tooth. No particular adverse clinical problems were observed during the follow-up period, and the succeeding permanent tooth erupted nearly at its normal position.
