Crowns are made to last a long life. However, problems may arise. Dental crown may chip, break, or falls off. If any of these happens, you should visit your dentist without delay. Dentist will look into the problem and determine how to treat the problem. If the crown is slightly chipped, slight repair is may work well. If the damage is significant, the tooth crown may need to be remade. There may be several reasons which cause dental filling or restoration fall out.

Decayed Tooth or Secondary Caries: The Tooth under your Crown got decayed with caries and on constant mastication forces chips off a fragment which looses the grip on the Crown which eventually falls off.

Breakage of Crown: Eating hard foods like chewing on Bones, eating Sugarcane directly, trying to open bottles with your teeth with crown, use your teeth to tear or break hard stuff etc can cause your crown to get cracks or even break. A simple crack can later turn big and break your crown.

 Chewing on Sticky food: Eating chewy food can loosen the bond between the tooth and the crown by affecting the cement which holds the crown to the tooth. After loosening the crown may just comes out with the candy.

Loss of Tooth Structure: Loss of tooth structure underneath the crown will also lead to dislodgement of crown as the surface area required to hold the crown is lost and the crown just falls off. The loss of tooth structure can be of many reasons fracture of tooth structure, caries of the tooth etc.

Faulty Cementation: Cementation is the procedure where dental cements like zinc phosphate or GIC are coated on the inner surface of the crown and fixed on to the tooth surface which fixes the crown to the tooth structure, if there were any air voids or irregularities in the cement mix the bond between the tooth and crown weakens and dislodgement of crown takes place.

Faulty Tooth or Crown Preparation: Defects in Tooth preparation (by dentist) or crown preparation (by dental lab technician) also lead to loss of crown.
