If two British engineers have their way, then many more people will soon be hearing voices in their heads.

James Auger and Jimmy Loizeau have created the "tooth phone," which consists of a radio receiver and a vibrator that can be shrunk down onto a microchip and implanted during dental surgery, according to a Reuters report.

Incoming calls would be transmitted to the in-tooth receiver and transferred to the inner ear via "bone resonance" (naturally!). So nobody need ever hear one of your phone calls again. And everybody will think you really are talking to yourself!

This is, of course, the ultimate gizmo for the spy-about-town or super-villain bent on world domination, but we're not sure that many other people will feel comfortable with a wireless molar. It's bad enough that Unstrung's fillings can already pick up radio signals.

Interestingly, the pair have not actually yet taken that final step themselves and implanted a phone in their own pearly whites, but they say that it is possible with today's chip technology.

"With the current size of microchips this is feasible. They are now small enough to implant in the tooth," Auger told Reuters.

To which Unstrung has just one question:
