My daughter does not do it but I do and I have a very long time. You can't just stop it.
I had great teeth with no decay, HOWEVER, I have 6 crowns and about to get another one becuase I grind so bad I crack my teeth. I've gone through 2 guards that were $500 each from the dentist.
I know I don't do it all the time, it comes in waves. I know when I have been though, because my head aches and jaws are stiff in the am.
See the pedi dentist and try to get a guard now.
