When placing a dental crown, it is reasonable to expect that it will last between 5-15 years. For those who keep excellent care of their mouths by using good daily or hygiene practices, a dental crown can last indefinitely. It’s safe to say that a crown that didn’t last somewhere between the 5-10 year mark would be a big disappointment to the dentist. Crowns are placed over a tooth to protect it from further damage, and if a crown doesn’t last as long as it was intended to, replacing it is necessary. There are different reasons why a dental crown may need to be replaced, and your dentist will able to know when the time is necessary.
Excessive wear of the crown from clenching and grinding the teeth is a common reason that a crown would need replacement. Because porcelain crowns are made to mimic the appearance and the characteristics of the surrounding teeth, they will generally undergo the same amount of wear that the natural teeth do. This is, in fact, a good thing because it means that the crown is appropriately placed in the mouth. However, excessive wear on the crown can break the seal or crack the crown.
Tooth decay that forms at the edge of the crown may cause the need to replace a dental crown. If the plaque accumulates and the cavity forms under the crown, the crown will need to be removed in order for the dentist to treat the cavity and then make a new replacement crown.
Receding gums are also a reason for replacing a dental crown. People may feel self conscious about the dark edge of their crown becoming exposed, or dentists may feel that the gum recession compromises the quality of the crown.
While all of the reasons above are valid reasons for replacing a dental crown, they can almost certainly be avoided with excellent dental hygiene. Brushing and flossing the teeth daily, wearing a mouth guard to protect the teeth from clenching or grinding, and seeing your dentist on a regular basis can help prevent decay and damage to a crown. Dental crowns can last a lifetime, but only with excellent care.
