Have you ever experienced dental discomfort even though you didn't have any cavities?

For some time now, one particular tooth has been bothering me.

It wasn't painful, but it felt strangely uncomfortable when drinking cold water or chewing hard food.

I got a checkup because I thought I might have a cavity, but they said there were no particular problems.

I am wondering if this kind of vague discomfort can also occur because my teeth have become sensitive.
