First, remove the crown from your mouth. You don't want to risk swallowing or accidentally inhaling. If you swallow it, it may pass without problem, but after digesting the system, you may not want it back in your mouth! If you accidentally inhale, you may become infected.
Call your dentist and make an appointment. Let the office staff know that your crown has fallen off. Give them as much detail as possible. They should adapt to you as quickly as possible (up to a few days).
Next, check the crown and look at your mouth. If your teeth are broken and located inside the crown, you must see the dentist before doing anything. If the crown looks hollow or it is not hollow, but there is a small metal rod (about the width of a paper clip), then you should be able to temporarily secure the crown in your mouth for permanent consolidation before seeing the dentist. Before proceeding, consult your dentist to see if you are using temporary cement to temporarily return the crown from the pharmacy.
Take a toothbrush and gently wipe away the crown and teeth inside the crown. After cleaning, make sure the crown and teeth are as dry as possible
Next, you will need temporary crown cement and you can purchase any pharmacy. A popular brand name for this type of cement is Recapit Temporary Crown Cement, which is a temporary glue that holds your crown on the underlying tooth structure until you can see the dentist.
Remember to be careful not to chew too much on the crown you have re-fixed. Do not chewy sticky foods such as caramel or taffy. Temporary cement is much weaker than the permanent cement used by the dentist.
