Not sure.

Anyone know... or have the same problem!!!! I brush my teeth everyday. And for some reason my teeth keep cracking. I usually have 2 teeth crack at a time. One on each side of my mouth. And I don't know why it's happening. My k-9 tooth on my right side has cracked last night and only have half a tooth. I know disgusting but jesus. I don't know what to do about my teeth. 😦😦😦 advice or similar situation?
