the dentist could not well reshape my existing teeth saying the older dentist did the cutting wrong exposing my nerve,anyway he did some drilling and fitted the new crown but now when i close my teeth my lower teeth touches the back of my crown, specially when i am eating (on side teeth) its continuously touching the back of my crown and is very un-comfortable, should i wait for 24hrs?tand if not will it require redoing all the procedure ? or just some drilling or grinding of the crown?
