Does the effect of shaving the tops of dental caps ruin the strength and integrity of crowns?

Hello,

Try to shave your dental Crown won’t cause affect the integrity of it. Also when you bite and not adapting the doctor have to do it. Don’t worry about it.

Good luck. 

Shaving the top of an old crown usually won't ruin the strength or integrity of the crown. There are a few factors however.  It depends on the type/ material of the old crown and how much of the old crown was removed or adjusted. But, usually some minor adjusting on an old crown is inconsequential.

Adjusting an old or new crown for that matter will not ruin the strength and integrity of the crown granted that there is enough material to support the adjustments. If the crown is a porcelain fused to metal crown (which is the case most often with the older crowns) the metal part of the restoration might show through after an adjustment.  Metal showing through is not pretty but that crown can still have a pretty long lifespan.  Hope that helps.  Cheers!
