Sir, occasionally a radiograph causes even the most experienced practitioner to take a step back (Fig. 1). In this case a 65-year-old male had experienced pain and swelling from the left angle of the mandible for several months prior to presentation. The mesial root appears to be displaced beyond the lower border of the mandible due to the formation of a large dentigerous cyst. The ectopic tooth is planned for removal via an extra-oral access under general anaesthetic in the coming weeks. We felt this was an interesting, eye-brow raising radiograph to share with our colleagues elsewhere.
