My teeth all Hurt when I drink cold and hot stuff?

They are sensitive teeth and the nerves in the roots of your teeth are feeling the hot and coldness. There is a toothpaste called Sensodyne that combats this, not sure if it is sold in the US if that is where you're from but I'm sure there is an equivalent.

See your dentist for better advice.

You have sensitive teeth. Sometimes that can be fixed with a deep cleaning done by your dentist. You can also try sensodine tooth paste, or a tooth paste meant for sensitive teeth.

You have sensitive teeth. Just use a toothpaste for sensitive teeth.

nothing is wrong that happens to everything the back of your teeth are very sensitive to temprature

Its because of the nerves in your teeth. I can't explain it but my mom is a dentist and that is what she said.
