meaning of dreams teeth

I had a dream that I was grinding my teeth and I couldn't stop no matter how hard I tried, It was like a terrible habit. And then one of my teeth fell out, I started crying and then my front tooth fell out. I felt like my whole life was ruined and I looked hideous and then all of a sudden my other front tooth fell out.. I realised all my teeth were crowded and that is why I was grinding them and then all my teeth started dropping one by one.. And then I woke up, very shaken..
