What is considered enough cold that it could permanently damage the nerves in your teeth?

A bet was made, that I wasn't able to finish a whole cup of slush in less than two minutes. I did.

Now however I'm having a noticeably painful time whenever liquid touches my teeth ~ cold or not. I chewed most of the slush with my back-teeth, and the cup containing it was perhaps 0,5 liters.

The weirdest thing is that I've never had a problem with eating or drinking cold food beforehand (easily being able to bite over frozen ice cream with my front-teeth without feeling a thing), and now I'm worried that I might have permanently damaged my nerves or the like.

I called the dentists-office, and without examining me they suggested me to get fluor (aka mouth wash) and use it for about a week ~ but any additional help or insight would be most appreciated at this point.

The slush-event happened about three days ago...

Answer
Cold will not likely cause any nerve damage in a tooth but what is more likely is a fracture from chewing the ice. Chewing ice is a good way to cause teeth to fracture. Fluoride is a natural desensitizer so that is why the rinse was recommended but it will not work if there is a fracture involved.
