Rock matriarch Sharon Osbourne turned the air blue on Tuesday (16Dec14) when one of her teeth fell out during a taping of her U.S. chat show The Talk.

Ozzy Osbourne's wife was discussing a hot topic on the show, when she noticed her tooth was loosening.

She exclaimed, "Oh s**t, my tooth is falling off (sic). It's an implant and I spent a bloody fortune and this f**king thing is falling out!"

The Tv host then removed the tooth and showed off the gap in her mouth.

She then proceeded to put the implant back into place, but it failed to stay put, leaving Osbourne no choice but to continue with the show without her tooth.
