Cannot floss around new crown?

Hello there,Crowns are designed to fit tight against the adjacent teeth to prevent food packing. It sounds like you just had this new crown cemented.  It may take you a few days to get used to your new crown.  I would recommend flossing daily.  If flossing does not get easier within a few days, contact your dentist. A contact that is too tight can lead to issues such as a build up of bacteria and decay. Good luck and I hope this helps.

Crowns should be tight against each other so that food doesn't pack, but you should be able to get floss between the teeth. It sounds as if there is something stuck between the two crowns. I suggest returning to your dentist and having them check with  floss to clean out the contact.
