Longevity of Dental Crowns

Dental crowns at SohoSmile are a fantastic solution for restoring damaged teeth and maintaining a beautiful, functional smile. They serve as protective coverings for weakened teeth, restoring their strength, shape, and appearance.

However, like any dental treatment, crowns come with a lifespan. How long do crowns last? Understanding the durability of dental crowns is crucial for managing your oral health and making informed decisions about your dental care.

Let’s dive into the factors that affect how long dental crowns last, and why choosing the right material and care practices is essential.

What is a Dental Crown?

A dental crown is essentially a cap that fits over a damaged tooth, restoring its original shape, size, and strength. Crowns are used to treat a variety of dental problems, such as large cavities, cracked teeth, or after root canal treatments.

Types of Dental Crowns

Crowns come in various materials, each with its unique properties. Common types include:

  • Porcelain Crowns – Known for their natural appearance, ideal for front teeth.
  • Metal Crowns – Durable and long-lasting, often used for back teeth.
  • Ceramic Crowns – A blend of natural appearance and strength.
  • Zirconia Crowns – Exceptionally durable, with a translucent finish that mimics natural teeth.

How Dental Crowns Are Applied

The process of getting a dental crown typically involves two appointments: one to prepare the tooth and create a temporary crown, and another to fit the permanent crown after it's custom-made in a lab.

Average Lifespan of a Dental Crown

General Expected Lifespan

On average, a dental crown at SohoSmile can last anywhere from 5 to 15 years. However, with proper care, some crowns can last even longer.

Common Materials Used and Their Longevity

  • Porcelain Crowns – 5 to 15 years.
  • Metal Crowns – 10 to 20 years.
  • Ceramic Crowns – 7 to 15 years.
  • Zirconia Crowns – 10 to 15 years.

What Affects the Duration of a Crown’s Life?

Several factors influence how long your dental crown will last. These include the material, your oral hygiene habits, and the location of the crown in your mouth.

Factors That Affect How Long a Crown Lasts

Material of the Crown

The material chosen for your crown plays a crucial role in its durability. Metal crowns, for example, last longer than porcelain crowns but might not provide the same aesthetic benefits.

Oral Hygiene Habits

Brushing and flossing regularly around your crown will prevent plaque buildup, which can weaken the bond between the crown and your tooth.

Tooth Location and Stress on the Crown

Crowns placed on back teeth, which endure more chewing pressure, may wear down faster compared to those on front teeth.

Bite and Clenching Issues

Teeth grinding (bruxism) can significantly shorten the lifespan of crowns. The extra pressure can cause cracks or damage to the crown material.

Age and Health of the Tooth Underneath

The health of the underlying tooth is just as important as the crown itself. A weakened or decaying tooth may lead to crown failure.

Types of Crowns and Their Durability

Choosing the right type of crown for your needs is critical to achieving long-lasting results.

Porcelain Crowns

Porcelain crowns offer an excellent natural look and are ideal for front teeth. However, they may not be as durable as metal crowns.

Metal Crowns

Made from alloys such as gold, these crowns are incredibly durable and resistant to wear. They are typically used for back teeth.

Ceramic Crowns

Ceramic crowns are durable and provide a natural aesthetic, making them a good choice for patients seeking a combination of strength and appearance.

Resin Crowns

Resin crowns are less expensive but tend to wear down faster and are more prone to fractures.

Zirconia Crowns

Zirconia crowns combine the best of both worlds—strength and aesthetic appeal. They are incredibly durable and long-lasting, often considered one of the best options for crowns.

Signs That Your Crown May Need to Be Replaced

Understanding when it’s time to replace your crown is key to maintaining optimal dental health.

Visible Damage or Cracks

If your crown shows visible cracks, chips, or discoloration, it might be time for a replacement.

Pain or Sensitivity in the Crowned Tooth

Increased sensitivity or discomfort can signal that your crown is no longer effective and may need to be replaced.

Discomfort While Chewing or Biting

Pain while chewing or biting down could indicate that the crown has shifted or is no longer fitting properly.

Loosening or Shifting of the Crown

A crown that feels loose or shifts out of place is no longer providing the protection your tooth needs.

Wear and Tear from Teeth Grinding

If you grind your teeth at night, it could result in the premature wearing down of your crown.

How to Make Your Dental Crown Last Longer

You can extend the life of your dental crown with a few simple habits and practices.

Proper Oral Hygiene Practices

Brush your teeth twice a day and floss daily around your crown to avoid plaque buildup and gum disease.

Avoiding Hard Foods and Habits Like Teeth Grinding

Limit hard foods that can damage your crown, and consider wearing a nightguard to protect your teeth from grinding.

Regular Dental Checkups and Maintenance

Routine visits to the dentist for cleanings and check-ups will ensure your crown is in good condition and allow for early detection of any potential issues.

Wearing a Nightguard If Necessary

If you grind your teeth at night, a nightguard can protect your crown from the added pressure.

The Process of Getting a Crown at SohoSmile

At SohoSmile, we use the latest technology and expertise to ensure your crown is placed with precision.

Consultation and Initial Examination

During your first appointment, our dentists will examine the affected tooth and discuss your options for crown material.

Preparing the Tooth for a Crown

The tooth is shaped and prepared to ensure the crown fits securely.

Temporary vs. Permanent Crowns

While waiting for your custom-made crown, we’ll place a temporary one to protect the tooth.

Final Placement and Adjustments

Once your permanent crown is ready, we’ll ensure it fits comfortably and adjust it for optimal function.

Common Reasons for Crown Failure

Crown failure can happen due to several reasons, but most can be prevented with proper care.

Poor Fit or Placement

If the crown is not placed correctly, it can lead to discomfort or early failure.

Material Degradation Over Time

Crowns, especially porcelain or resin ones, may wear down or become damaged over time.

Infection or Decay Underneath the Crown

If the underlying tooth is not properly treated or the crown is not sealed well, infection can cause the crown to fail.

Physical Trauma to the Crown

Accidents or trauma to the mouth can damage your crown.

Poor Oral Care Habits

Failing to maintain proper oral hygiene can weaken the crown and lead to complications.

How to Care for Your Crown After Placement

Proper care is essential to ensure the longevity of your crown.

Avoiding Sticky and Hard Foods

Avoid sticky and hard foods that can dislodge or damage your crown.

Brushing and Flossing Around the Crown

Be sure to clean around your crown to prevent plaque buildup and ensure its longevity. You can also visit your dentist twice a year for dental cleanings.

Avoiding Teeth Clenching and Grinding

If you clench or grind your teeth, consider wearing a nightguard to protect your crown from damage.
