My tooth is sensitive~~

Lately, I feel my teeth chattering when I drink something cold.

Is this also related to age...

A few days ago, I drank black tea and my teeth felt very sensitive, so I couldn't drink it. It was a beverage I used to enjoy drinking, but can this happen?

Is there a treatment for this?? I don't think there are any particular problems, but I do occasionally experience coldness, and I can't drink hibiscus at all.ㅠ

I saw others drinking through a straw, so I wonder if that's the best method.ㅠ
