Abstract	Background: Severe ankylosis is rare and any affected teeth are unlikely to exfoliate spontaneously. If left untreated, subsequent complications can develop. Case presentation: We treated a boy aged 10 years with a tooth affected by ankylosis for a long period, which caused dislocation of the mandibular second premolar. Because adjacent teeth were inclined, there was insufficient space for extraction and space regaining therapy was required. Conclusion: It is important to properly determine the severity of the ankylosed tooth when it is detected and provide treatment with appropriate timing.
