칫솔질로 구멍이 커진게 아니라 치석이 빠져서 생긴 틈을 보고 구멍이 커졌다고 착각했을 가능성이 더 큽니다.

I've recently realized the importance of dental health, so I use interdental brushes and dental floss after brushing. However, after repeatedly brushing the same areas where debris is stuck between teeth, I've noticed that tiny holes have grown between my teeth, above the gum line. I use an I-shaped 0.7mm toothbrush, and I'm wondering if anyone else has experienced this. I'm also worried that it might cause tooth sensitivity later on.
