Concern) Dental caries.

I am quite old... As I age, my teeth become crooked.

As it shifts, the upper teeth touch the lower teeth, and the front teeth...

It was a little broken and came out... At first, what was attached?

I did it, but after a while, the size increased a little more.

It broke apart... I was really surprised.

I think it's probably because of the teeth.

I'm still unsure whether I need to do the proofreading again.

I'm really worried about time management if I do it now.
