For those working in international espionage and crimes against humanity, a tooth containing a fatal dose of cyanide is de rigeur, lest one be unfortunate enough to get captured.

For those of us having a particularly bad day in the office, who no longer wish to talk to clients on the phone, the anaesthetic tooth should be sufficient.

Plenty of cavities in my teeth anyhow, one more won't make much difference. Also, having to go through the procedure would ensure that it was only used in the most desperate of circumstances.

I wasn't sure if I could get anything over the counter (to carry in my pocket) which would provide the level of numbness required.

Plus I thought that this way people would be less likely to accidentally/deliberately overdose and do themselves some serious damage. More controlled, y'see.

If you filled the tooth with an anaesthetic gas under compression, you could make boring people at parties drop unconscious.

'Remember the tooth!' Yueh hissed, 'The tooth!'

Assuming it was your own tooth that you filled, you're more likely to make the bored person drop unconscious.

And this is a downside how?

I have a single malt scotch filled tooth. I was getting into it so often that it was getting expensive to replace, so now I just keep it on my desk.

How, exactly, do cyanide-filled teeth work?

Exactly like anaesthetic-filled teeth, but with cyanide.
