How Long Do Crowns Last? 

Beitrags Menu

Dental crowns are essential in the world of dentistry, serving as protective caps for damaged or weakened teeth. But, like all things, they have a limited lifespan. So the question: “How long do crowns last” is justified.

What are dental crowns?

Dental crowns, also known as dental caps or tooth crowns (dental restoration), are common dental restorations used to protect, strengthen, and enhance the appearance of a damaged or weakened tooth.

These crowns, including dental bridges, are custom-made to fit over a patient’s natural tooth, providing a durable and aesthetically pleasing solution to a variety of dental issues.

Here is some more general information about dental crowns:

Purpose of Dental Crowns

  • Protection: Crowns are used to protect a tooth that has been significantly damaged by decay, injury, or dental procedures like root canals.
  • Strength: They restore a tooth’s strength and structural integrity, preventing further damage.
  • Aesthetics: Crowns can improve the appearance of a tooth by concealing discoloration, misshapenness, or other cosmetic imperfections like a broken tooth.
  • Functionality: They enable the proper functioning of a tooth, allowing for effective biting and chewing by being a large filling for missing teeth.

Types of Dental Crowns

Dental crowns come in various types, each with its own set of advantages and considerations. The choice of crown type depends on factors like the location of the tooth, aesthetic concerns, and budget. Gold crowns for example are an “old” type of crowns, which is not used anymore by modern dental clinic in Turkey like the Cosmedica Dental.

Here’s more information about some of the modern types of dental crowns:

1. Ceramic Crowns

hese crowns are made entirely of porcelain, making them highly aesthetic and natural-looking. They can be color-matched to adjacent teeth.
Ceramic crowns are an excellent choice for front teeth where appearance is a primary concern. They are biocompatible and don’t trigger allergic reactions.
They are more prone to chipping or fracturing compared to other crown materials, so they may not be suitable for molars or teeth with heavy biting forces.

2. Porcelain fused to Metal Crowns (PFM) / Porcelain crowns

PFM crowns have a metal substructure covered with a porcelain exterior. This combination provides both strength and aesthetics.
PFM crowns are versatile and can be used for both front and back teeth. They offer a balance between appearance and durability.
In some cases, the metal substructure may be visible as a dark line near the gumline, which can affect aesthetics.

3. Metal Crowns

Metal crowns are typically made from alloys containing metals like gold, platinum, or base metals. They are known for their durability and strength.
Metal crowns are the most robust and long-lasting option. They are often used for molars and teeth that endure significant chewing forces.
The metallic color makes them less suitable for front teeth, and some patients may find their appearance undesirable.

4. All-Resin Crowns

These crowns are made of dental resin, a type of plastic. They are more affordable than other crown types.
All-resin crowns are economical and can be color-matched to natural teeth. They are an option for restoring front teeth in some cases.
They are less durable and more susceptible to wear and chipping, making them less suitable for molars or teeth subjected to heavy forces.

5. Zirconia Crowns

Zirconia crowns are made from a strong, tooth-colored ceramic material called zirconia.
These crowns offer an excellent balance of strength and aesthetics. They are highly durable and don’t cause allergic reactions.
Zirconia crowns are a popular choice for both front and back teeth, but they are more opaque than other options, which can affect their appearance.

Crown Placement Process

  1. Diagnosis: The dentist assesses the tooth’s condition and determines if a crown is necessary.
  2. Tooth Preparation: The tooth is reshaped to accommodate the crown.
  3. Impression: An impression is taken to create a custom crown that fits perfectly.
  4. Temporary Crown: A temporary crown is placed while the custom one is fabricated.
  5. Permanent Crown Placement: Once the custom crown is ready, it is cemented onto the prepared tooth.

Lifespan of Dental Crowns

How long do crowns last? The longevity of dental crowns can vary depending on several factors. On average, a well-maintained dental crown can last anywhere from 10 to 15 years. Some crowns may even endure for 25 years or more, while others may need replacement sooner.

Factors affecting the longevity of dental crowns

The following factors can influence how long your dental crown will last:

  • Material Used: The material of the crown plays a significant role in its durability. Ceramic crowns are more susceptible to chipping, while metal crowns are exceptionally durable.
  • Oral Hygiene: Maintaining excellent oral hygiene is vital to prolong the life of your crown. Regular brushing, flossing, and dental check-ups are essential.
  • Teeth Grinding: Habitual teeth grinding or clenching can put extra stress on your crown, leading to premature wear and tear.
  • Diet: A diet high in sugary and acidic foods can deteriorate the dental cement holding the crown in place.
  • Accidents and Trauma: Accidents can lead to crown damage. Wearing a mouthguard during activities that may result in head or face injuries is advisable.

Caring for Your Dental Crowns

  • Brush and floss regularly to prevent gum disease and decay.
  • Avoid chewing hard objects or ice, which can damage the crown.

  • Visible Damage: Cracks, chips, or fractures in the crown material.
  • Tooth Sensitivity: Increased sensitivity to hot or cold substances.
  • Loosening: The crown may feel loose or fall off.

When to Replace Dental Crowns

Dental crowns may need replacement if they show signs of wear, such as visible damage, tooth sensitivity, or loosening. Regular dental check-ups help dentists monitor the condition of crowns and recommend replacement when necessary.
