How Long Do Dental Crowns Last and What Affects Their Lifespan?

Dental crowns are a popular and reliable solution for restoring damaged teeth. Whether you’re addressing a broken tooth, covering a root canal, or enhancing a tooth’s appearance, dental crowns provide a durable solution. But how long can you expect your dental crowns to last, and what factors influence their longevity? At Dawson Modern Dentistry in Matthews, we understand how important it is for our patients to make informed decisions about their dental care. In this blog, we’ll explore the lifespan of dental crowns, what affects their durability, and how to ensure they last as long as possible.

What Are Dental Crowns?

A dental crown is a cap that covers a damaged or decayed tooth to restore its shape, size, and function. Crowns can be made from various materials, including porcelain, metal, or a combination of both. The material chosen often depends on the tooth’s location, the patient’s preferences, and the dentist’s recommendation.
Dental crowns are often used for teeth that have undergone significant damage or decay, providing both aesthetic and functional benefits. They are commonly placed on teeth that have undergone root canal therapy, are severely worn down, or have large fillings.

Lifespan of Dental Crowns

On average, dental crowns can last 10 to 15 years, but with proper care, some can last even longer. However, the longevity of your crown will depend on several factors, including the material used, your oral habits, and the health of the underlying tooth.

Factors Affecting the Lifespan of Dental Crowns

1. Material of the Crown
   Porcelain Crowns: Porcelain crowns offer a natural look and are highly popular for visible teeth, such as those at the front of your mouth. These crowns are durable but may wear down over time, especially in individuals who grind their teeth.
   Porcelain-Fused-to-Metal Crowns: These crowns combine the strength of metal with the aesthetic appeal of porcelain. They are more durable than pure porcelain but may still chip or wear.
   Metal Crowns: Metal crowns, made from gold or other alloys, are incredibly durable and can last 15 years or more. However, they are less natural in appearance, making them more suitable for back teeth, where they’re less visible.
   Zirconia Crowns: A newer material, zirconia crowns are highly durable and resistant to wear. They offer both strength and aesthetic appeal and are becoming increasingly popular for both front and back teeth.
2. Oral Hygiene Practices
   Regular brushing, flossing, and routine dental check-ups play a significant role in the longevity of your dental crowns. Plaque buildup around the crown can lead to tooth decay, which may affect both the crown and the tooth underneath. Maintain proper oral hygiene to avoid complications that could shorten your crown’s lifespan.
3. Diet and Habits
   Certain habits and dietary choices can significantly impact your crowns. Eating hard foods, chewing ice, or using your teeth to open bottles can put excessive stress on your crown, potentially leading to damage or failure. Additionally, a diet high in sugar can increase the likelihood of tooth decay, which can compromise the integrity of your dental crowns.
4. Teeth Grinding (Bruxism)
   Teeth grinding or clenching can significantly reduce the lifespan of dental crowns, especially if you do it frequently. People who grind their teeth, particularly at night, may wear down their crowns much faster than those who don’t. If you’re prone to grinding your teeth, consider wearing a nightguard to protect your crowns and natural teeth from damage.
5. Underlying Tooth Health
   The health of the tooth beneath the crown is crucial to its longevity. If the tooth becomes weakened or decayed over time, it can affect the crown. For example, a tooth with a large cavity or severe decay may not provide a strong foundation for a crown. In such cases, the crown may need to be replaced sooner than expected.
6. Proper Fit
   A crown that doesn’t fit properly can lead to discomfort and damage to the surrounding teeth. If the crown isn’t properly aligned or bonded to the tooth, it could lead to problems such as gum irritation, decay, or an improper bite. Ensuring the crown is well-fitted from the start can help it last longer.

How to Care for Your Dental Crowns

Taking care of your dental crown is key to making it last for years. Here are some tips to extend the lifespan of your crown:

• Maintain Good Oral Hygiene: Brush and floss regularly, focusing on the area around the crown to prevent plaque buildup.
• Avoid Hard Foods: Don’t bite into hard objects like ice or candy that could damage your crown.
• Wear a Mouthguard: If you grind your teeth at night, talk to your dentist about getting a custom mouthguard to protect your crowns.
• Visit Your Dentist Regularly: Routine dental check-ups can help identify issues early, preventing major problems down the line.

How to Know When to Replace a Crown?

While dental crowns are designed to last a long time, they won’t last forever. Over time, the crown may become loose, crack, or wear down. If you notice any of the following symptoms, it might be time to schedule a visit to Dawson Modern Dentistry in Matthews:

• Pain or Sensitivity: If your crown is causing discomfort or sensitivity, it could indicate that there’s a problem with the underlying tooth or the crown itself.
• Visible Damage: Cracks, chips, or wear on the crown’s surface may require replacement.
• Loose Crown: If your crown feels loose or falls off, it’s essential to see your dentist promptly to avoid further complications.
