Dental Crown Longevity: How Long Do Crowns Last?

Crowns are among the most reliable and versatile dental restorations used today. Whether it is used to restore a broken tooth, to strengthen a weak tooth, or to enhance your smile, a dental crown will have an important role in maintaining your oral health for years to come.

However, a common question from patients is, "How long do crowns last?"

Let’s take a look at how long dental crowns last, what factors may influence their longevity, how to prolong their life, and when they need to be replaced.

What is a Dental Crown?

A dental crown is a cap that is shaped like a tooth. Dentists employ crowns to repair weak, broken, or decayed teeth.

A crown will fit over your entire tooth like a snug hat. To make the crown fit, the dentist will have to remove a small amount of your enamel before bonding your new crown to the tooth.

Dental technicians can make crowns out of many materials, such as resin, metal, and porcelain.

When Would You Need a Dental Crown?

Crowns serve several purposes. You may need a dental crown to:

• Strengthen a weak tooth.
• Protect and support a cracked tooth.
• Restore a worn-down or broken tooth.
• Hold a dental bridge in place.
• Cover a severely stained or discolored tooth.
• Cover a root canal-treated tooth.
• Cover a dental implant.

How Long Do Crowns Last on Average?

So, how long do crowns last?

On average, most crowns last between 10 and 15 years, but they can last 20 to 30 years or even a lifetime with proper oral hygiene and care.

The dental crown lifespan depends on multiple factors, including:

• Material type (porcelain, zirconia, metal, etc.)
• The skill of your dentist
• Your oral hygiene routine
• Your diet and habits (like teeth grinding)

Here’s a quick overview of how long different types of crowns can last:

While these are general estimates, remember that no dental restoration lasts forever, even the most durable crown for a tooth eventually wears down or loosens with time.

Do Crowns Last Forever?

Many patients wonder: Do crowns last forever? The short answer is: no, crowns don’t last forever.

Even though materials like zirconia and gold are incredibly strong, they still face natural wear and tear from years of chewing, grinding, and exposure to temperature changes in the mouth. Additionally, the tooth beneath the crown remains vulnerable to decay if oral hygiene isn’t maintained.

With consistent care and professional check-ups, however, a well-made crown can last for decades, some lasting 30 years or more.

What Affects How Long Crowns Last?

Several factors influence how long crowns last, including both the material used and your personal habits. Let’s explore the key ones:

Crown Material

Different materials have different durability levels. Metal and zirconia crowns are the strongest, while porcelain offers superior aesthetics but may be more prone to chipping.

Oral Hygiene

Even though the crown itself can’t decay, the tooth under it can. Poor hygiene can lead to decay along the gum line, compromising the crown for teeth.

Bite Force & Grinding

If you grind your teeth (a condition called bruxism), it can drastically shorten the dental crown lifespan. Wearing a night guard can protect your crown.

Quality of the Dental Crown Procedure

The expertise of your dentist tooth crown specialist matters. A well-fitted crown ensures proper bite alignment, reducing stress and extending longevity.

Dietary Habits

Chewing on hard objects (ice, nuts, pens) or sticky candies can crack or loosen your crown.

Gum Health

Healthy gums are essential for crown stability. Gum disease can cause recession, exposing the edges of the crown and leading to sensitivity or decay.

Accidents or Trauma

A sudden fall or impact can chip or loosen even the strongest tooth crown.

Benefits of Dental Crowns

Here are the benefits of a dental crown :

Dental crowns reinforce weak or damaged teeth, allowing you to bite and chew comfortably without pain or risk of breakage.

Long-Lasting Solution

With proper care, dental crowns can last 10–20 years or more, making them a durable and cost-effective restoration.

The Dental Crown Procedure: Step-by-Step

What Happens If a Crown Gets Damaged?

If your tooth crown becomes chipped, cracked, or dislodged, don’t panic, but do act quickly. Avoid chewing on that side and schedule an appointment with your dentist.

Your dentist tooth crown expert will examine the damage and determine whether the crown can be repaired or must be replaced. Temporary crowns can be fitted to protect your tooth in the meantime.

Even the best crowns can wear down over time. Here are signs that indicate your crown may need repair or replacement:

• Pain or sensitivity when biting down
• Visible cracks or chips on the crown
• The crown feels loose or wobbly
