How Long Do Dental Crowns Last?

June 9, 2021 | Dental Surgery,General Dentist,Implant Dentistry

A dental crown is a popular way to repair a damaged tooth. It is customized to match your other teeth, creating a seamless solution for a damaged tooth that would otherwise detract from your smile and reduce functionality. If you currently have an appointment to receive a dental crown, you may have questions about the maintenance and upkeep of a crown, as well as how often you will need to replace it. Find out how long most dental crowns last on average. Then, talk to your dentist for more information.

What Is the Purpose of a Dental Crown?

A dental crown may be the recommended treatment for many different dental problems. A crown may be used to restore a cracked tooth or prevent a damaged tooth from breaking, as well as to protect a tooth that is fragile after a root canal. Crowns are especially common after a cavity or another problem leaves a large filling without enough tooth remaining to hold it in place. In this case, a crown may be used to strengthen the remaining tooth in preparation for the filling.

Different Crowns Have Different Lifespans

Today’s dental crowns are made with the latest materials and technologies and are very strong and durable. However, no crown will last forever. Most have lifespans of 5 to 15 years (with an average of 10 years) before they need to be replaced. The material you choose for your dental crown can determine about how long it will last:

  • Metal
  • Ceramic
  • Porcelain
  • Zirconia
  • Composite resin
  • Multiple materials

Studies show that gold crowns and crowns that use porcelain fused to metal tend to last the longest, with gold crowns lasting an average of 10 years (or much longer with proper care). Zirconia crowns are the least likely to split or crack and come with a lifespan of 10 to 15 years or longer. Ceramic, all-porcelain and all-resin crowns, on the other hand, are not as strong and may wear down faster.

You will need to consider both cost and durability when choosing your dental crowns. Your dentist will also make suggestions based on the location of the tooth, how much of it will show when you smile, the function of the tooth and how much natural tooth you have remaining. Discuss your options in detail to choose the right crown for you and your needs.

How You Can Improve the Longevity of Your Dental Crowns

How long your dental crown lasts also depends on how well you take care of it. When properly created and well cared for, dental crowns of any material can last a decade or longer. Caring for your dental crown requires professional cleanings with your family dentist at least twice per year. It also means brushing your teeth at least twice per day, flossing daily and avoiding certain foods that could cause damage to your crowns.

For example, chewing on ice or other hard foods can crack a crown, especially one made out of porcelain. Sticky or chewy foods may dislodge crowns. Finally, if you grind your teeth at night, your dentist may recommend a nightguard to protect your crowns and other teeth.

How Can You Tell if a Crown Needs to Be Replaced?

If you already have a dental crown, you should know when it needs to be replaced to avoid related dental problems, such as a cracked or damaged crown. If you notice any of the following issues, it may be a sign that your dental crown needs replacing:

  • Your bite feels uneven
  • The crown appears to be moving or unstable
  • The gums around the crowned tooth are receding
  • You are feeling pain in or around the crowned tooth
  • The crown is discolored or chipped
  • The crown is more than five years old

Regular cleanings with your dentist can help you stay on top of dental crown care. Your dentist can check on its condition and let you know when it needs to be replaced. If you are experiencing issues with your dental crown, contact the dental professionals at Dental on Central right away for care.
