Is it true grinding your teeth can damage a crown?

[CindyC]

I grind my teeth when I sleep. I can't seem to stop this practice and I have no idea if it will cause damage to my crowns. Is there a method to stop me from grinding my teeth in my sleep? Will my crowns be damaged by the habit?

[Dr Mohsen J. Esfahani]

yes grinding or clenching teeth when sleeping can damage crowns and can cause porcelain fracture. If you do grind or clench your teeth, we would recommend having a nightguard fitted. There are different options such as soft nightguard, hard nightguard or NTI and you should ask your dentist regarding the best option for your case.
