A Thought While at the Dentist

I'll get away from the foodie topics for a little bit.  

I was recently at the dentist.  (No cavities, yay.)  But I just had a random thought while I was there.  I happen to have an eye phobia type thing.  I'll probably never get contacts or laser eye surgery and I don't even like seeing things happen to eyes in TV.  Like there's an episode of Family Guy, where Death accidentally gouges everyone's eyes with his scythe and I shiver or something.  ("Mufasa...")


Anyway, so the hygienist is cleaning my teeth and using those hook/pick things.  Now, those are double sided and I wondered whether there's been an accident and they accidentally drop the tool and for some reason the other side gets at the patient's eye.  That would be awful.  A google search didn't bring up anything, but I assume it might happen at least once.  Like there's an earthquake while you're getting your teeth picked at.  Fortunately, I wear glasses.
