I have a really sensitive tooth. Not emotionally sensitive, like it cries when I don't pay enough attention to it, but more like I feel a great deal of pain when I drink cold drinks or even breath in cold air.

This is really curtailing my eating, especially since my favorite meal is ice cube salad with cold water dressing.
So, I tried some home remedies that I made up.

The first was to eat tons of ice cream so as to make me immune to the cold. As you can imagine, that didn't work.
The second, blowing compressed air onto it, just sent me into fits of rage. I didn't really do that, but I can imagine that it would hurt a great deal.

The third thing was to visit a dentist. What did he do? He blew compressed air onto it to be sure. I didn't really need that.

I'm having it repaired next week. Should be nice.
