How Long Do Crowns Last?

CrownCrowns are among the most versatile of dental restorations, and they’re used for everything from fixing a cracked or broken tooth to forming the top of a dental implant. Because they’re used in such widely divergent situations, it’s helpful to understand the factors that impact how long a crown will last in your mouth before needing to be replaced.

Factors influencing the lifespan of a dental crown

  1. The reason the crown is being placed. Some conditions are strongly stabilized by the addition of a crown – for example, dental implants, root canals, or a broken tooth. However, in some cases a crown is used in a situation that may continue to prove challenging, such as in the case of severe tooth decay or as a restoration for teeth worn down by bruxism (teeth grinding). This may impact the crown’s longevity.
  2. The material of which the crown is made. There are several choices in terms of material for crowns. Gold/metal is very strong, but can present aesthetic issues for some patients. Porcelain crowns are popular because of the natural look they provide, but may not always be as strong as gold or metal crowns. Porcelain fused to metal (or PFM) crowns offer strength and aesthetic beauty, although issues can arise if a patient experiences severe gum recession around this type of crown. Today there are also some very strong materials that provide the strength of metal with the beauty of porcelain. Zirconia crowns are just one of those options that may be recommended.
  3.  The practitioner placing the crown. It’s important that your cosmetic dentist accurately assess your oral health and properly diagnose the reason the crown is needed. Dental insurance often won’t pay for a crown to be replaced more often than once every five years, but most dentists prefer to place a restoration that will last far longer than that.

Research on the lifespan of dental crowns indicates that most are quite durable. A survey of more than 2,000 specialists revealed a survival rate of 97 percent at 10 years, and 85 percent at 25 years. It’s not unrealistic to expect your crown to last at least ten years, and potentially a lot longer.

“Dental crowns are the restoration of choice in many situations, but that broad range of usefulness introduces some variance in how long a crown might last,” says Dr. Carol Ford, a cosmetic dentist with a practice in central Phoenix. “Look for a well-qualified practitioner who uses quality materials and insists on good craftsmanship.”
