Splint

I think my teeth are wearing down and my jaw is also affected because I grind my teeth or clench my jaw while sleepingㅠ

During the day, I consciously try not to grind my teeth, but when I sleep, it seems I do it unconsciously without even realizing it.

According to someone I know, I heard that hospital splints are quite expensive, so the cost is burdensome, and I also think there might be some side effects, so I'm hesitant.

Should I still do it to protect my teeth?
