My dental crown came off, what do I do now?

Do I need to get a new crown or do I ask the dentist to use the old one that just came off?

take the crown to ur dentist he will cement it again if its still good. (the older the less chance its still good) 40% of crown need to be cemented twice at least ;). casual
Reply:Call your dentist and do what they tell you to do.
Reply:cement back the old one, unless its damaged.
Reply:save the crown and bring it to the dentist so that he can cement it back in, otherwise u will be charged for a new crown and will have to wait for another one to be prepared for u.
