Dental crowns are a reliable and effective way to restore damaged teeth, but one of the most common questions patients ask is, "How long do dental crowns last?" In this blog, we’ll explore the lifespan of dental crowns, the factors that impact their durability, and how you can extend the life of your crown for a lasting, beautiful smile.
On average, dental crowns can last between 10 to 15 years. However, with proper care, many patients report that their crowns last even longer—up to 20 years or more. The longevity of your crown depends on several factors, such as the material used, how well you care for it, and the location of the crown in your mouth.
While dental crowns are designed to be long-lasting, several factors can affect their lifespan:
Crowns can be made from different materials like porcelain, zirconia, and metal. For example, zirconia and metal crowns tend to be more durable, especially for back teeth that endure heavy chewing forces.
Maintaining good oral hygiene, including brushing and flossing regularly, is essential to prevent decay or gum disease around the crowned tooth.
Crowns placed on back molars may wear down more quickly due to the pressure of chewing, while crowns on front teeth tend to last longer.
If you grind or clench your teeth, your crown may wear down faster. Wearing a night guard can help protect your crown and natural teeth from this damage.
Hard or sticky foods, like ice or candy, can place extra stress on crowns and cause them to wear down prematurely.
The type of crown you choose can influence how long it lasts. Here’s a breakdown of the most common types of dental crowns and their average lifespans:
All-Resin Crowns: Typically last 5 to 7 years. These are more affordable but less durable than other materials.
Porcelain-Fused-to-Metal (PFM) Crowns: Last around 10 to 15 years, offering a combination of strength and aesthetics.
All-Ceramic or All-Porcelain Crowns: Can last 10 to 15 years. These are ideal for front teeth and provide a natural appearance.
Zirconia Crowns: Known for their strength, zirconia crowns can last 15 to 20 years or more, especially with proper care.
Metal Crowns (Gold or Stainless Steel): The most durable option, lasting 20+ years. These are ideal for back molars where strength is key.
While dental crowns are durable, following these care tips can help extend their life:
Even with the best care, dental crowns may eventually need to be replaced. Here are the signs that it’s time for a replacement:
Wear and Tear: If your crown looks worn down or has chips and cracks, it’s time for a replacement.
Gum Recession: If your gums start to recede around the crown, it can expose the tooth underneath to decay.
Pain or Sensitivity: If you experience pain or increased sensitivity around the crowned tooth, there may be an issue with the crown’s fit or condition.
Looseness: A crown that feels loose or wobbly should be replaced immediately to avoid further damage.
