My crown is too big and has already been cemented on

When the last tooth back is crowned it is common for suble changes to take place in the TM Joint.  The last tooth is a pivotal fulcrum.  When it is prepared the joint alters and it often results in needing numerous adjustments.  Sometimes gagging yourself can reset the joints and muscles.This is a much bigger problem when the last tooth is part of a bridge and can result in TMD issues.Removing and replacing crown can make the problem worse.  It won't chip a healthy tooth.  Gold is still my favorite restorative for the last molar because it is soft and forgiving but almost everyone prefers tooth colored materials today.  Gold would "self adjust"Ira L Shapira DDS, D,ABDSM, D,AAPM, FICCMOChair, Alliance of TMD OrganizationsDiplomat, American Academy of Pain ManagementDiplomat, American Board of Dental Sleep MedicineRegent & Fellow, International College of CranioMandibular OrthopedicsBoard Eligible, American Academy of CranioFacial PainDental Section Editor, Sleep & Health JournalMember, American Equilibration SocietyMember, Academy of Applied Myofunctional Sciences

Hello there,It sounds like another adjustment may be needed.  I would recommend returning to your dentist for a simple adjustment that would only take 5-10 minutes in the dental chair.  Good luck and I hope this helps.

It sounds like the crown needs a bit more adjusting to remove interferences when you are doing a chewing or grinding motion.  Also sometimes a scraping noise can also be due to an area of the crown that was adjusted and not polished afterwards.  Return to your dentist and they should be able to do this pretty quickly.
