S.L.
My son is almost 6 and he still grinds his teeth so loud when he sleeps I can hear it at night from my room. It's really an awful sound, but the dentist doesn't seem to be concerned. I know I used to do it when I was little and I don't anymore (didn't stop until I was probably 10 years old though, so it can continue for awhile). I ignore it anymore...he can't help it and I can;t do anything about it.
