Wondering How Long Dental Crowns Last? Here's the Answer!
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.
The Typical Lifespan of Dental Crowns
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.
Key Factors That Impact the Durability of Your Crown
While dental crowns are designed to be long-lasting, several factors can affect their lifespan:
Material of the Crown
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.
Oral Hygiene
Maintaining good oral hygiene, including brushing and flossing regularly, is essential to prevent decay or gum disease around the crowned tooth.
Location of the Crown
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.
Teeth Grinding (Bruxism)
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.
Dietary Habits
Hard or sticky foods, like ice or candy, can place extra stress on crowns and cause them to wear down prematurely.
How Long Do Different Types of Crowns Last?
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.
5 Tips for Making Your Dental Crown Last Longer
While dental crowns are durable, following these care tips can help extend their life:
1
Maintain Excellent Oral Hygiene:
Brush twice a day and floss regularly to keep the surrounding gums and teeth healthy.
2
Visit Your Dentist Regularly:
Regular dental check-ups allow your dentist to monitor your crown and ensure it’s in good condition.
3
Wear a Night Guard if Needed:
If you grind or clench your teeth, a custom night guard can protect your crown from excessive wear.
4
Avoid Hard and Sticky Foods:
Minimize consumption of hard foods like nuts or ice, and avoid sticky candies that could damage your crown.
5
Use Non-Abrasive Toothpaste:
Choose a toothpaste that is non-abrasive to protect both your natural teeth and your dental crowns.
When Should You Consider Replacing Your Crown?
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.
