4 reasons really:

1)young people have big healthy nerves in their teeth, so for instance in your front teeth, which are quite thin, something cold can get them aching.

2)a cavity will cause a tooth to be sensitive when it gets cold

3)root sensitivity. If the gums recede and the root of the tooth is exposed, then cold will cause sensitivity

4)an abscess or infection under the tooth will cause aching if the area gets cold, contracts and causes a pressure increase.

Anti-sensitive toothpaste like Sensodyne will help for root sensitivity

A filling will help for a cavity

A root canal or an extraction helps if it is an abscess

Good luck!

I have the same problem. It's just sensitive teeth. I am unable robots into ice lollies and ice cream. You can get tooth paste for this. Like sensodine xx

I also have sensitive teeth. I use sensodyne tooth paste. It helps some

sounds like sensitive teath try changing your toothpaste for one that is for sensitive teath and as it costs just a little more than a good toothpaste its very cheap to treat and good luck
