Hi I am a dental hygienist and have been for the last ten years...we have parents ask this very same question all the time...there is nothing you can do to stop her from grinding and it shouldn't do any harm other than they will wear down over time...by the time you see any wear it should be about time for her adult teeth to come in...as long as she is not complaining about any pain or acting like she is having pain she should be ok...but if you want a dentist to look at them that would be fine too
