DS2 clacks his teeth together when he's eating, the sound is quite noticeable ( and irritating). Is this quirk caused by the way his teeth or jaw is aligned or just something he does? He is an adult by the way so i can't ask the dentist as he goes on his own. He can't seem to stop himself doing it, just wondered if any dentists had come across this.
If it's an unconcious habit i guess I'll just have to play music at the dinner table.
