Sharon Osborne faced an unusual emergency this week, when her tooth fell out during a live broadcast. The star was presenting The Talk and chatting with panellists Julie Chen, Sara Gilbert, Aisha Tyler and Sheryl Underwood when she exclaimed  "Oh s***! My tooth is falling off!". The former X Factor judge then pulled the tooth from her mouth, explaining that it was an implant that had come loose. "Oh no problem, it's one of those implants. It's an implant!" she said. "I spent a bloody fortune on this f****** thing, it's falling out! What do I do? No seriously has anyone got any glue? We have to take an emergency tooth break." Despite her missing tooth, Osborne continued with the show and carried out an interview with Friends actress Lisa Kudrow.
