Ice-cold sensation symptoms

There is no problem usually when I eat food.

Chewing on fruits or sweet chocolates sometimes makes my teeth feel cold.

I have a feeling.

Is it because of a cavity? Since the symptoms aren't persistent, I'm just debating whether to go to the dentist or not.

They say it's better to get treatment quickly for cavities to avoid more trouble.

It's a symptom that happens occasionally, so I'm afraid of the dentist and keep delaying going~ Should I go?
