How Long Do Dental Crowns Last?

Dental crowns are a great way to fix damaged or discolored teeth, but how long do they really last? Our Point Pleasant dentist explains what affects a crown’s lifespan and offers tips on how to make yours last as long as possible.


What Are Dental Crowns?

Dental crowns are caps shaped like teeth that cover a damaged tooth to restore its shape, size, strength, and appearance. They’re often used when a tooth is badly damaged from decay or injury or after major dental work, like a large filling.

Crowns can be made from porcelain, ceramic, metal, or a mix of these materials.


Types of Dental Crowns

  • Porcelain Crowns: Porcelain looks the most natural, which makes it a popular choice for front teeth. This type of crown is durable and resistant to stains but can chip or crack more easily than other materials. 
  • Ceramic Crowns: Made from materials like zirconia, ceramic crowns also look natural and can be matched to your tooth color. They’re strong and resistant to wear, so they work well for both front and back teeth. 
  • Metal Alloy Crowns: Crowns made from gold or other metals are extremely long-lasting. They’re often used for back teeth because they can handle heavy chewing without damage.
  • Porcelain-Fused-to-Metal Crowns: These crowns combine the realistic look of porcelain with the strength of a metal base.

How Long Do Dental Crowns Last?

The short answer is that it depends. There are a few different factors that can affect how long your dental crowns last, including, but not limited to:

  1. Material

    2. The type of crown matters. Porcelain and ceramic crowns usually last 5 to 15 years, while metal alloy or porcelain-fused-to-metal crowns can last 10 to 30 years or more with the proper care.

  2. Oral Hygiene

    3. Brushing, flossing, and regular dental visits are the best ways to ensure the longevity of your crowns. Plaque and tartar buildup can lead to decay or gum disease, which can affect the crown.

  3. Grinding and Clenching

    4. Grinding or clenching your teeth can wear down your crown or cause it to chip. Wearing a nightguard can help protect it.

  4. Location in the Mouth

    5. Crowns on back teeth, which do most of the chewing, usually wear out faster than those on front teeth.


How Can I Extend the Lifespan of a Dental Crown?

In addition to practicing good oral hygiene, you should avoid hard or sticky foods like candies or ice that could damage your crown. If you notice any problems, such as discoloration, looseness, or sensitivity, contact our Point Pleasant dentist as soon as possible.


Signs It’s Time to Replace Your Crown 

While dental crowns are built to last, they might need replacing over time for several reasons: 

  • Wear and Tear: The crown can wear down, chip, or crack, affecting its function and appearance. 
  • Decay: If the tooth under the crown gets a cavity, the crown may need to be replaced to fix the underlying issue. 
  • Gum Recession: As the gums recede, the crown may become exposed and cause sensitivity. 
  • Loose Fit: A loose or dislodged crown will need to be replaced to prevent further damage.
