[Concern] Sometimes elementary school students suck their fingers even when they are sleeping.

When the child was young, they had a habit of sucking their thumb.

I used to fall asleep sucking my fingers just like sucking on a pacifier.

When I was young, I would bite my fingers first when I wanted to sleep or try to fall asleep.

When I was about 7 years old, I had already stopped that habit, but when I was deeply asleep or tossing and turning, I would unconsciously suck my fingers.

I still have this habit, so I am worried about what kind of negative effects it might have on my teeth.

I'm worried about my teeth alignment, but I'm also concerned about developing malocclusion...

Does the habit of thumb sucking have a negative effect on teeth?

I'm worried.
