I'm worried that I might have a problem because I continue to feel discomfort after cavity treatment.

Two years ago, I developed a cavity and slightly scraped it off.

But lately, that tooth sometimes feels sensitive and when pressed with my hand

It hurts when I eat something hard.

When I went to the dentist and had an X-ray taken, they said there was nothing abnormal.

These symptoms continue.

Is it rotting more inside?

Should I undergo root canal treatment?

They say there is nothing wrong, but I still feel uncomfortable and suffocated.
