why does my teeth hurt when i drink cold water

Ah, buddy! That's because of tooth sensitivity. When the protective layers of your teeth get worn down, the tiny tubes in the teeth expose the nerves to the elements which can cause pain.

Yeah, and cold water especially can trigger this pain since it can reach your nerves quickly. Not like I have to care, I don't drink water, I drink... well, you know...

You might want to try using a desensitizing toothpaste. It helps block the tubes in your teeth to reduce the pain. Also, avoid brushing your teeth too hard. Be gentle, buddy!

And if that doesn't do the trick, seeing a dentist might be a good idea. They might suggest a filling to cover the exposed nerve. Don't worry, it's as easy as watching a vampire movie. Well, except for Twilight, that's a whole other kind of terror.
