How long do dental crowns last on teeth?

March 18, 2024

Dental crowns serve as essential tools in restorative dentistry as they provide strength, protection, and aesthetic appeal to damaged or weakened teeth. Whether it's due to decay, trauma, or cosmetic concerns, crowns offer a durable solution for enhancing both function and appearance. However, a common question that arises among dental patients is, "How long do dental crowns last?"

Let us explore the typical lifespan of different types of crowns, what influences how long they last, how to recognize signs of wear and tear, and what you can do to make sure your crowns stay in good shape for as long as possible. 

What are Dental Crowns?

Dental crowns are protective coverings or "caps" that are placed on top of the tooth to restore its shape, size, strength, and appearance. They are commonly used in dentistry to address various dental issues that cannot be resolved with fillings alone. They are made from various materials, like porcelain, metal, or a combination of both, to exactly match the color and shape of your natural teeth. 

Crowns are typically recommended for situations such as repairing severely decayed or fractured teeth, strengthening teeth after root canal therapy, covering dental implants, or improving the look of misshapen or discolored teeth.

Before exploring the topic of how long do dental crowns last on teeth, let's first understand why they are necessary.

When Do You Require Dental Crowns?

If a cavity has progressed to the point where a root canal is necessary, a crown is often placed over the treated tooth. However, there are various other situations where a dental crown might be recommended:

How Long Do Dental Crowns Last?

Dental crowns aren't designed to last forever, but they can stay in good condition for about 15 to 30 years with proper care. Gold crowns, which are known for their durability, can last even longer, but they're also more expensive and not as commonly used. When a dentist suggests a dental crown, it's usually to either save a damaged tooth or improve its appearance.

Over time, crowns can wear down or even break, especially if you eat a lot of hard foods like nuts. Since everyone has different eating habits and dental care routines, it's hard to pinpoint exactly how long your crown will last.

Common Reasons for Replacing a Dental Crown

A dental crown usually needs to be replaced when it shows signs of significant damage or dental problems. You can often spot this damage by looking for chips or cracks on the crown's surface. These chips can be risky because they might cause mouth injuries due to sharp edges or could even be swallowed and cause harm to the throat. Additionally, a damaged crown can leave the protected tooth exposed to infection.

Another reason to replace a crown is if you start experiencing new pain, signs of infection, or notice plaque buildup around the base or edges of the crown. These signs suggest that the tooth underneath might be infected or further damaged, requiring both crown replacement and attention from your dentist to address the underlying issue.

Factors Impacting How Long Do Crowns Last On Teeth

Several things can affect the lifespan of your dental crown. Here are a few important ones to keep in mind:

Bad habits:

Grinding or clenching your teeth can really take a toll on your crown. Use a night guard to help protect your crown and your other teeth. It's also wise to avoid biting down on hard items like ice or candies.

Oral hygiene:

Not taking proper care of the teeth can lead to your crown wearing out faster. Make sure to keep up with your oral care routine to prevent decay underneath the crown.

Materials used:

The type of materials used in your crown can make a difference in how long it lasts. Metal crowns are considered more durable than porcelain ones, although porcelain is often preferred for its appearance, especially for front teeth.

Since crowns are versatile and can address many dental issues, it's important to talk to your dentist about which type of crown is best for your situation.

Extend the Lifespan of Your Dental Crown

Taking care of your dental crown is key to keeping it in good shape for as long as possible. Here are some simple ways to improve its lifespan:

Keep up with oral hygiene:

Brush your teeth regularly, ideally twice a day, and floss daily to prevent plaque and avoid decay around the crown. Using fluoride toothpaste can strengthen your teeth and help prevent cavities.

Watch out for bad habits:

Don't grind or clench your teeth, as they can damage the crown. If you grind your teeth at night, wear a night guard to protect both your crown and natural teeth.

Be mindful of what you eat:

Don't bite down on hard foods like ice or candies, as this can chip or crack your crown. Limit sticky or sugary foods that can contribute to decay around the crown.

Schedule regular dental check-ups:

Visit your dentist for regular dental check-ups and cleanings to keep an eye on the health of your crown and surrounding teeth. Early detection of any issues can help prevent further damage and prolong the life of your crown.

Choose the right materials:

Work with your dentist to choose the crown material that best suits your needs and lifestyle. While porcelain crowns are more aesthetically pleasing, metal or porcelain-fused-to-metal crowns may offer greater durability and longevity.


Understanding the lifespan of dental crowns is essential for maintaining optimal oral health. With proper care and attention, dental crowns can last between 10 to 30 years. However, factors such as oral hygiene, habits, and materials used significantly affect their longevity.

What can impact the lifespan of dental crowns?

The lifespan of dental crowns can be influenced by various factors, including oral hygiene practices, habits like teeth grinding, diet, and the materials used in the crown's construction.

What Happens When Crowns Wear Out?

As time passes, crowns can become weaker and more prone to cracking. This can create spaces where food particles get trapped, increasing the risk of decay. It's important to schedule a dental check-up if your crowns have been in place for more than ten years to address any signs of wear and tear.
