While your new crown and the abutment anchoring it to your jaw is designed to be durable, there are a few rare occasions where it might become loose or fall out. Blows to the face and issues with chronic gum disease are two of the more common sources of a problematic crown.
If you have a crown that is loose, or has just fallen out, you should call your dentist as soon as possible. They can help you determine the best course of action and schedule an appointment to resolve it quickly. If for some reason you can call your dentist, there are a few things you can do to help manage the situation.
If your crown is loose, try to avoid wiggling it, as this could damage the abutment inside.
If a crown falls out, you can inspect the abutment, but resist the temptation to clean it. Your dentist will determine the best way to clean the area. If your crown was knocked out by a blow to the face or other injury and you have blood in your mouth, you can clean the area by rinsing with lukewarm salt water.
If an issue with the cement caused the crown to fall out, you should see a small nub of tooth or dull gray metal. The crown itself should also be hollow. In this situation, your dentist will can often cement the crown back into place.
If the abutment is fractured or broke off at the gum line you will see some of it inside the crown, you might need to have a root canal to provide a new abutment to anchor the crown.
