Do Crowns Have an Expiration Date?

Dental crowns are a common dental treatment that can greatly improve the function and appearance of damaged or discolored teeth. However, many patients may wonder if dental crowns expire or how long they can expect them to last.

Dental Crowns: What are They?

Dental crowns are custom-made restorations that cover the visible portion of a tooth, providing protection and support to damaged or weakened teeth. They can be made from ceramic, porcelain, metal, or a combination of materials. There are several types of dental crowns, such as all-metal, porcelain-fused-to-metal, all-ceramic, and all-resin crowns, each with unique benefits and drawbacks.

The procedure for placing dental crowns typically involves preparing the tooth by removing decay and shaping it to accommodate the crown. An impression of the prepared tooth is taken, and a temporary crown is placed while the permanent crown is fabricated. Once the permanent crown is ready, the temporary crown is removed, and the new crown is cemented in place.

Do Dental Crowns Expire?

While dental crowns do not have a specific expiration date, they have a typical lifespan, which can vary depending on several factors. According to the National Library of Medicine, the average lifespan of a dental crown is more than 90% at five years and between 50-80% at 15 to 20 years. However, some crowns can last up to 25 years or more with proper care and maintenance.

Factors Affecting the Lifespan of Dental Crowns

Factors that affect the lifespan of dental crowns include the material used, the patient’s oral hygiene habits, the location of the crown within the mouth, and the patient’s overall health.

For example, crowns made of metal tend to be more durable and last longer than those made of porcelain or resin. Crowns located in areas of the mouth that experience higher chewing forces, like the molars, may wear out faster than those in less-stressed areas. Health conditions like dry mouth can increase your risk of gum disease and loosen your crown so it no longer fits and needs to be replaced.

Signs That Dental Crowns Need Replacement

Signs that indicate dental crowns need a replacement include visible wear or damage, persistent pain or discomfort, increased sensitivity, or loosening of the crown. Regular dental checkups are essential to monitor the condition of your dental crowns and address any potential issues early.

How to Care for Dental Crowns

Proper dental hygiene is crucial for maintaining dental crowns and prolonging their lifespan. Brushing your teeth twice a day, flossing daily, and using an antibacterial mouthwash can help keep your teeth and gums healthy, reducing the risk of gum disease that can compromise the longevity of your crowns. To increase the lifespan of your dental crown, use the following tips:

  • Avoid hard, sticky, or abrasive foods that can damage the crown material
  • Wear a mouthguard if you grind your teeth at night or during sports activities
  • Visit your dentist for checkups and professional cleanings
