Dental Crown Lifespan

In the world of modern dentistry, dental crowns stand out as a tried-and-true method of restoring damaged teeth. However, keeping them functional requires attentive care beyond the initial treatment. This raises an important question: How long do crowns last, and what exactly determines their longevity?


With a commitment to exceptional patient care, Vivid Dental Raleigh aims to provide insight into the various factors influencing the lifespan of crowns and strategies to help them last longer. Let’s dive into what it takes to make dental crowns go the distance!

When and Why Dental Crowns Are Needed

Dental crowns are essential restorations that restore the integrity of teeth impacted by decay or damage. They are carefully designed to fit over the tooth, restoring its natural strength, appearance, and function.

Crowns are used to:

  • Shield weak teeth from damage
  • Restore already broken or severely worn-down teeth
  • Cover and support a tooth with a large filling
  • Hold a dental bridge in place
  • Cover misshapen or discolored teeth
  • Complete a dental implant restoration

When you choose dental crowns, you are not just restoring teeth; you are investing in your long-term dental health and your self-esteem.

How Long Do Dental Crowns Typically Last?

Generally, they can last anywhere from 10 to 15 years, with some lasting even longer under the right conditions. Understanding their expected longevity is crucial for patients considering this restorative option. 

Types of Crowns and Their Longevity

One of the primary determinants of how long crowns last is the material from which they are made. Here’s a breakdown of common crown types and their typical lifespans:

Porcelain-Fused-to-Metal (PFM)

PFM crowns combine the strength of metal with the natural look of porcelain, typically lasting 10 to 15 years. However, the porcelain layer can chip over time and reveal the metal underneath near the gumline.

All-Metal Crowns

With materials like gold or metal alloys, these crowns provide impressive durability, making them ideal for patients prone to strong bites or teeth grinding. The trade-off is that they may not blend seamlessly with natural teeth due to their metallic look.

All-Ceramic or All-Porcelain Crowns

While these crowns are highly aesthetic and closely resemble natural teeth, they are not as durable as metal or PFM crowns. The lifespan of these crowns usually ranges from 10 to 15 years.

Zirconia Crowns

Known for their exceptional strength and aesthetics, zirconia crowns are highly durable and resistant to chipping or cracking. They are a great option for both front and back teeth, making them a versatile choice.

Other Factors Affecting Crown Durability

While the material of the crown is a key consideration, numerous other factors contribute to its overall longevity. Recognizing these elements can empower patients to take necessary actions to preserve their crowns.

Placement of the Crown

The location of the crown can greatly influence its durability. Crowns fitted on molars or other teeth involved in heavy chewing face more stress than those placed on front teeth. This increased pressure and wear can shorten the crown’s lifespan.

Oral Hygiene Practices

Effective care for dental crowns is key to ensuring they perform well over time. Neglecting proper oral hygiene may lead to gum complications that not only jeopardize your gum health but also weaken the crown’s support.

Bite Force and Habits

Patients who grind their teeth or apply excessive bite force may inadvertently compromise the durability of their crowns. The additional pressure from these habits can lead to wear, fractures, or even complete failure of the crown over time.

Diet and Lifestyle Choices

Although dental crowns are designed to withstand normal chewing forces, certain dietary choices can pose risks. Hard or sticky foods, such as ice, hard candy, or chewing gum, can damage the crown. Limiting these types of foods can help prevent cracks or dislodges.

Moreover, lifestyle habits like smoking and excessive alcohol consumption can weaken the integrity of both the natural tooth and the crown. These habits may also increase the risk of gum disease, further shortening the crown’s lifespan.

How to Maximize the Longevity of Dental Crowns

Proper care of your dental crowns is of utmost importance not only for their durability but also for preventing other dental issues. Below are a few effective strategies to protect your crowns and ensure they last as long as possible:

  • Daily Oral Hygiene: Commit to brushing your teeth twice a day with fluoride toothpaste and flossing daily. Pay special attention to the area where the crown meets the gumline, as this is where decay can often occur.
  • Invest in Night Guards: If you tend to grind your teeth at night, investing in a custom night guard can protect both your natural teeth and crowns from undue wear.
  • Avoid Harmful Habits: Be mindful of actions that can compromise the integrity of crowns, like nail-biting, chewing on non-food items, or using teeth for tasks they aren’t meant for.
  • Limit Acidic and Sugary Foods: Foods and drinks high in sugar or acid can lead to plaque buildup and tooth decay around the crown. Limiting their consumption can help protect your dental work.
  • Schedule Regular Dental Visits: Make it a priority to attend regular dental checkups. These appointments allow your dentist to assess the condition of your crowns and overall oral health.

Make these practices part of your daily routine, and you will be well on your way to enjoying your crowns for many years without worry.

Knowing When to Replace a Dental Crown

Just like any dental restoration, crowns have a lifespan, and being attentive to the indicators of wear can save you from inconvenience and costly repairs.

Warning Signs to Watch For

Be proactive and schedule an appointment at Vivid Dental Raleigh if you notice any of the following symptoms:

  • Persistent pain or sensitivity around the crowned tooth
  • Visible cracks, chips, or wear on the crown's surface
  • A loose or dislodged crown that feels unstable
  • Receding gums around the crown, exposing more of the tooth or crown base
  • Discoloration or changes in the appearance of the crown
  • Difficulty chewing or biting due to discomfort

The Replacement Process

If a replacement is necessary, the procedure is typically straightforward and mirrors the initial crown placement. Here’s what to expect during the process:

  1. Your dentist will first assess the health of the underlying tooth.
  2. The old crown will be removed, and the tooth will be cleaned and reshaped if necessary.
  3. A new impression will be taken, and a temporary crown may be placed while your permanent crown is fabricated.

Once the new crown is ready, your dentist will cement it in place, ensuring a comfortable and functional fit. The replacement process is generally quick, and with proper care, your new crown should last just as long as the original.
