Teeth grinders get some help

Sure, snorers can be loud. But for really cringe-worthy nighttime noise, it's hard to beat a dedicated grinder. With jaw muscles clenched tight -- perhaps because of stress or misaligned teeth -- a grinder can create a crunching sound reminiscent of two icebergs passing in the night. Some people grind with a force of nearly 1,000 pounds per square inch, enough to crack teeth and obliterate fillings.
