What to Do with Filed Down Molar Crown?

you may need to return for more filing, or bite adjusting.  Often this takes very little effort, but sometimes a few visits.  And once in a blue moon, the entire crown needs to be redone.

 

There is no "fault", as it could be a lab thing, could be a dentist thing, could even be a patient thing, so rather than find fault it is best to simply get it fixed.

As previously mentioned there needs to be trust in the doctor patient relationship.  If this is not there then you may need to find a better dental relationship.  As far as the crown goes, they can ususally be adjusted as long as there is adequate crown structure left to fine tune.  If it is thin in the area of needed adjustment, the crown may need to be replaced

Usually a crown can be adjusted to make it "feel more comfortable".  Sometimes it just has to be redone. 

Crowns are a very predictable and excellent longterm solution for a broken down tooth.  However nothing is 100% predictable, and so sometimes the only way to fix something that isn't working is to redo it.
