Dental crowns and bridges are popular restorative solutions for patients with missing, decayed, or damaged teeth. These devices not only restore the functionality of your teeth but also improve the overall appearance of your smile. However, one common question many patients ask is, “How long do dental crowns and bridges last?”

In this comprehensive blog post, we’ll dive deep into the lifespan of crowns and bridges, what factors influence their durability, and how you can take care of them to ensure they last as long as possible.

What Are Dental Crowns and Bridges?

Before we explore how long dental crowns and bridges last, let’s briefly review what they are and their purpose in restorative dentistry.

• Dental Crowns: A dental crown is a cap placed over a tooth that has been damaged by decay, trauma, or other issues. It’s designed to restore the tooth’s shape, size, and strength. Crowns can be made from various materials, including porcelain, ceramic, gold, and resin.
• Dental Bridges: A dental bridge is used to replace one or more missing teeth. It consists of a false tooth (or teeth) anchored to adjacent natural teeth or dental implants. Like crowns, bridges can be made from various materials, depending on the patient’s needs and preferences.

Average Lifespan of Dental Crowns and Bridges

On average, dental crowns and bridges last between 10 to 15 years. However, this lifespan can vary depending on several factors, such as the materials used, the location of the restoration in your mouth, your oral hygiene habits, and your lifestyle choices.

• Dental Crowns: Crowns typically last between 10 and 15 years. Porcelain crowns may last slightly less than metal crowns, but they offer a more natural appearance.
• Dental Bridges: Dental bridges can last from 5 to 15 years, with some high-quality materials and proper maintenance extending their lifespan even further.

Factors That Influence the Longevity of Crowns and Bridges

Several factors can impact how long dental crowns and bridges last. Let’s take a closer look at the key influences on their durability.

1. Material Choice

The type of material used to fabricate your crown or bridge plays a significant role in how long it will last. Here are some common materials used in dental crowns and bridges:

• Porcelain: Porcelain crowns and bridges offer a natural appearance and blend well with your natural teeth. However, they can be more prone to wear and breakage compared to metal-based restorations. They typically last around 10-15 years.
• Porcelain-fused-to-metal (PFM): This material combines the aesthetics of porcelain with the strength of metal. It’s durable and more resistant to chipping, with a lifespan of around 10-15 years.
• Gold: Gold crowns and bridges are extremely durable and resistant to wear. They are a great option for molars, where chewing pressure is highest. Gold restorations can last 20 years or more, though they’re less aesthetic than porcelain-based options.
• Zirconia: Zirconia is a strong and durable material that mimics the appearance of natural teeth. It offers great longevity, often exceeding 15 years, and is resistant to staining and wear.

2. Location of the Restoration

The position of the tooth being restored also affects how long the crown or bridge will last. Teeth at the back of the mouth experience more pressure from chewing and grinding. As a result, restorations placed on molars or premolars may wear out more quickly than those placed on front teeth. If your restoration is on a molar, opting for a more durable material like gold or zirconia may be beneficial.

3. Oral Hygiene and Care

Maintaining good oral hygiene is essential for extending the lifespan of your dental crowns and bridges. Plaque buildup can cause decay in the surrounding teeth, leading to potential damage or failure of your restoration. Regular brushing, flossing, and professional cleanings are essential to maintain the health of your gums and teeth.

• Brush regularly: Brush your teeth at least twice a day using fluoride toothpaste. Make sure to clean around your crowns and bridges to avoid plaque buildup.
• Floss daily: Use floss or an interdental brush to clean between your teeth and around your restorations. Special floss threaders or dental tools can help clean around bridges.
• Visit your dentist regularly: Professional cleanings every 6-12 months will help maintain your restorations and detect any potential issues early.

4. Bruxism (Teeth Grinding)

Teeth grinding (bruxism) is a common problem that can significantly reduce the lifespan of dental restorations. If you grind your teeth at night, the constant pressure and friction can wear down crowns and bridges. To protect your investment, your dentist may recommend a custom nightguard to reduce the effects of bruxism.

5. Diet and Lifestyle Habits

Certain dietary habits and lifestyle choices can affect the longevity of dental crowns and bridges. Avoid biting hard objects like ice, pens, or your nails, as this can lead to fractures. Sticky foods, like caramel or chewing gum, can also dislodge crowns and bridges.

• Limit sugary foods and drinks: Sugar can promote the growth of bacteria that lead to tooth decay. A healthy diet can help prevent damage to your dental restorations.
• Avoid excessive alcohol and smoking: Smoking and drinking alcohol can contribute to gum disease, which can undermine the stability of your crowns and bridges.

6. Accidental Trauma

Accidents or injuries to the face and mouth can also damage dental crowns and bridges. While crowns made from metal or zirconia may be more resistant to breakage, porcelain crowns are more vulnerable to chipping or cracking. Always wear a mouthguard if you play contact sports to protect your dental restorations from impact.

How to Extend the Life of Your Dental Crowns and Bridges

Now that you understand the factors that influence the lifespan of crowns and bridges, here are some practical tips to extend their life:

• Maintain excellent oral hygiene.
• Use a nightguard if you grind your teeth.
• Visit your dentist for regular checkups.
• Avoid biting hard or sticky foods.
• Avoid smoking and limit alcohol consumption.
• Protect your smile with a mouthguard if necessary.

Signs That You Need to Replace Your Dental Crown or Bridge

Over time, even with excellent care, dental crowns and bridges may require replacement. Here are some signs to watch out for:

• Pain or discomfort: If you experience pain around the crown or bridge, it could indicate that the restoration has become loose or the underlying tooth has decayed.
• Visible damage: Cracks, chips, or discoloration in your crown or bridge may suggest it’s time for a replacement.
• Food getting stuck: If food keeps getting caught around your restoration, it might be a sign that it’s no longer fitting properly.
• Gum recession: If your gums have receded around your crown or bridge, it could expose the underlying tooth, leading to decay or infection.

Conclusion

Dental crowns and bridges are highly effective and durable solutions for restoring damaged or missing teeth. With proper care, these restorations can last for many years, typically ranging from 10 to 15 years. Factors like material choice, oral hygiene, and lifestyle habits all play a significant role in determining the lifespan of your crowns and bridges.

By following proper oral care practices and visiting your dentist regularly for checkups, you can ensure that your dental restorations serve you well for years to come. If you notice any issues with your crowns or bridges, don’t hesitate to consult your dentist for timely repairs or replacements.
