The Blue Tooth was the third story in the first series of The Companion Chronicles. It was produced by Big Finish Productions. It was written by Nigel Fairs and featured Liz Shaw. It was notable for being the one of the few stories to pit the Third Doctor against the Cybermen. Until the publication of The Piper in 2015, this was the only Third Doctor story to use the Cybermen as its main antagonists.

Publisher's summary Edit

"I suppose that was one of the Doctor's most endearing qualities: the ability to make the bizarre and the terrifying seem utterly normal."

When Liz Shaw's friend Jean goes missing, the Doctor and U.N.I.T. are drawn to the scene to investigate. Soon Liz discovers a potential alien invasion that will have far-reaching affects on her life... and the Doctor is unexpectedly re-united with an old enemy...
