For some handy expressions at the dentist, to follow my post on Gallipoli and Ljubljana, idly consulting the relevant section of my Turkish phrasebook, my imagination is captured by the expression

Bitmedi, tekrar gelmelisiniz
Come back, I haven’t finished!

This reminds me of Nigel Barley’s comment on his first fieldtrip to Cameroon (The innocent anthropologist, p.109–10), as he emerges bloodied after having his two front teeth pulled out with pliers:

I had fallen into the obvious trap that anyone in a dental surgery, wearing a white coat and prepared to extract teeth, was a dentist.

Cf. David Sedaris, “When you are engulfed in flames”. Also under Language learning: a roundup, note especially That is the snake that bit my foot.
