Over the past two years, I've picked up a bad habit of grinding my teeth. I think I mostly do it while in bed, but I catch myself at random times throughout the day and have to force myself to stop.
My question is: can teeth grinding contribute to tooth decay? I haven't had a new cavity since grade school, but last time I went to the dentist, I had two. I'm wondering if it's because I'm digging the bacteria or food particles further into my teeth, or because I'm causing damage to my teeth that the bacteria can then seep into.
Also, does anyone have any idea why I've recently started grinding my teeth or any advice on how to stop?
Thanks!
