Why Do Crowns Break?

Crowns well procesed by the lab do not usually break.

The bite registration called oclusio nis very important when you take impression for a crown. If the bite registration is not correct than the crown fitting is not correct.An incorrect bite creates high spots on the crown. When the patient bites he will hit first the crown.If that is not corrected the porcelain will break eventually.

Dental Crowns can break or fracture for a number of reasons. Sometimes forces applied to a Crown or tooth can be excessive . Other times its possible that the Crown failed due to less than ideal tooth preparation causing the Restoration to lack Structural  Durability even when normal biting forces are applied to it.  Whatever the cause of failure is though its most important to gain an immediate replacement before more problems develop. Fractured Crowns can lead to open contacts allowing for food to wedge in between your teeth causing acute Periodontal or gum irritation. Over a period of time this can lead to even more serious Periodontal problems such as Bone Loss and unhealthy gum pockets to form. Broken or Fractured Crowns can also lead to recurrent decay over periods of time. A fractured Crown should be replaced as soon as possible!
