I also found out about my habit of clenching my teeth when I visited the dentist.

I didn't even know I had a habit of clenching my teeth, but I found out only after hearing that at the dentist.

Come to think of it, I realized I tend to clench my jaw quite often when I'm concentrating on work.

I was only thinking about dental issues, but since I hear that habits like this can also affect the teeth or jaw joint, I think I need to pay attention.

It's an unconscious habit, so it's not easy to fix.
