But, while a crown is meant to be a permanent solution, it is not indestructible.
How is a Crown Placed?When you need a crown, your dentist must first prepare your tooth. This means filing the tooth down to allow the crown to fit over it and allowing it to form a seal to keep out anything that might contaminate it. An impression is taken and sent to a lab to create your restoration, which is usually made out of ceramic, but can also be made from porcelain fused to metal or all metal.
While your restoration is being created, a process that takes about one to two weeks, your dentist will give you a temporary crown. When your permanent one is ready, your dentist will cement it in place.
Tooth DecayWhile the crown is meant to seal out bacteria, if you don't take proper care of your teeth, bacteria can build up where the crown meets the gum line. It can then get under the crown and cause decay to the remainder of your tooth. With enough decay, your tooth will become weak, and the crown may become loose or even fall out.
Too Much Wear
Too much wear on a crown, particularly one made of ceramic or porcelain fused to metal, can cause damage to it. Wearing it down can weaken it or cause it to crack or break. Often, wear is caused by bruxism, or the clenching and/or grinding of your teeth.
Biting Too Hard or Eating Hard Food
Ceramic is not unbreakable. While ceramic, and porcelain fused to metal, crowns are made to withstand the pressure of normal biting and chewing, if you have a tendency to bite hard, you can potentially damage the restoration, chipping, cracking or breaking it. Eating foods that are particularly hard and crunchy also pose a risk.
Some types of damage done to your crown can be easily fixed, but others may require you to get a brand new one. If your crown has suffered damage, contact our office right away.
