How Long Do Crowns and Bridges Last?

If you're considering restorative dental work such as a crown and bridge, one of the first questions that come to mind is: How long will they last? Whether you’re an athlete needing strong dental protection or a general patient aiming to restore function and aesthetics, it’s a fair concern. Dental treatments are an investment—both in your smile and your finances.

In this article, we’ll explore how long crowns and bridges typically last, what affects their lifespan, how much they cost, and how to care for them to make them last as long as possible.

What Are Dental Crowns and Bridges?

Before we dive into longevity, let’s clarify what these treatments are.

What is a Dental Crown?

A dental crown is a tooth-shaped "cap" placed over a tooth to restore its shape, size, strength, and appearance. Crowns are often used after root canals, for cracked teeth, or to cover a large filling when not enough tooth structure remains.

What is a Dental Bridge?

A dental bridge replaces one or more missing teeth. It consists of artificial teeth (called pontics) anchored by crowns placed on the adjacent natural teeth or implants. Bridges help restore bite, maintain facial structure, and prevent remaining teeth from shifting.

How Long Do Crowns and Bridges Last?

Average Lifespan of Crowns

Dental crowns typically last 10 to 15 years, but with excellent care, they can last 20 years or more. Some patients report their crowns lasting even 25 to 30 years, especially when made from high-quality materials and maintained with proper oral hygiene.

Average Lifespan of Bridges

Dental bridges generally last between 5 and 15 years, depending on several factors such as the materials used, placement technique, and patient care. Just like crowns, well-maintained bridges can exceed their average lifespan significantly.

Factors That Affect the Lifespan of Crowns and Bridges

1. Material Used

• Porcelain-fused-to-metal (PFM): Durable and aesthetic, but may wear down or show metal margins over time.

• All-ceramic or zirconia: Highly aesthetic and durable, especially for front teeth.

• Gold or metal alloys: Extremely durable, ideal for molars, but less common due to aesthetics.

2. Oral Hygiene Habits

Proper brushing, flossing, and professional dental cleanings are essential. Neglecting your oral hygiene increases the risk of decay around the crown or the supporting teeth of a bridge.

3. Diet and Lifestyle

Hard foods, sugary snacks, and frequent snacking can wear down or damage your dental work. Also, habits like chewing ice or using your teeth as tools can reduce lifespan.

4. Teeth Grinding (Bruxism)

Grinding or clenching can crack or wear down crowns and bridges. Wearing a night guard can prevent damage and extend the life of your restorations.

5. Placement and Fit

Skillful placement and perfect fit play a considerable role. A poorly fitted crown or bridge can cause discomfort, improper bite, and early failure.

Crown and Bridge Cost: What Should You Expect?

Average Cost of Dental Crowns

The crown and bridge cost varies depending on material, location, and insurance coverage.

• Porcelain-fused-to-metal crown: $800–$1,500

• All-ceramic crown: $1,000–$2,000

• Gold crown: $1,200–$2,500

Average Cost of Dental Bridges

• Traditional 3-unit bridge: $2,000–$5,000

• Implant-supported bridge: $4,000–$15,000 (more stable, but more expensive)

Pro tip: Dental insurance often covers part of the crown and bridge cost, especially if the treatment is deemed medically necessary. Always check with your provider.

How to Prolong the Life of Your Crown and Bridge

Here are some simple but effective ways to ensure your investment lasts:

1. Practice Excellent Oral Hygiene

Brush twice a day with fluoride toothpaste and floss daily, especially around the crown edges and bridge abutments.

2. Visit Your Dentist Regularly

Dental check-ups every 6 months help monitor the condition of your restorations and catch issues early.

3. Avoid Harmful Habits

Stop biting fingernails, chewing pens, or opening packages with your teeth.

4. Wear a Mouth guard (If you’re an Athlete or Bruxer)

If you grind your teeth or play contact sports, wearing a custom mouth guard can protect your dental work from damage.

Signs That Your Crown or Bridge May Need Replacement

• Pain or discomfort in the area

• Visible cracks or chips

• Loose crown or bridge

• Receding gums exposing the tooth or base

• Bad odor or taste, indicating trapped bacteria

If you notice any of these signs, contact your dentist promptly.

Special Considerations for Athletes

Athletes, particularly in contact sports, should take extra precautions with their dental crowns and bridges. A custom-fitted sports mouthguard is highly recommended. It not only protects natural teeth but also extends the life of any dental restoration.

Moreover, athletes are often prone to dehydration, which can reduce saliva and increase plaque buildup, threatening crown longevity. Hydration and oral hygiene are key.

FAQs about Crowns and Bridges

Q1: Can crowns and bridges be whitened?

No. Unlike natural teeth, crowns and bridges do not respond to whitening treatments. If you plan to whiten your teeth, does it before getting these restorations for a uniform color match.

Q2: How do I clean around a dental bridge?

Use floss threaders, interdental brushes, or water flossers to clean under and around the bridge. Your dentist can demonstrate the best technique for your case.

Q3: Can I eat normally with a crown or bridge?

Yes, once adjusted. However, avoid extremely hard or sticky foods that can dislodge or damage them.

Q4: Will my crown or bridge look natural?

Absolutely. Today’s materials (like zirconia and porcelain) are designed to match the natural color, translucency, and shape of your teeth.

Q5: Are there financing options for the cost of the crown and bridge?

Yes. Many dental clinics offer flexible payment plans or work with third-party financing providers. Check with your dental office.

Crowns and bridges are more than cosmetic enhancements—they restore functionality, prevent further dental issues, and improve overall oral health. When maintained properly, they offer long-term benefits that far outweigh the upfront cost of crowns and bridges.

Whether you’re a competitive athlete or someone simply looking to protect and perfect your smile, knowing how long crowns and bridges last—and how to care for them—can ensure you get the most out of your dental investment.
