Dental Crowns: How Long Can You Expect Them to Last?
How long do dental crowns last? Learn about durability factors to maintain your crowns longer.
Dental crowns are a common and effective solution for restoring damaged, decayed, or aesthetically unappealing teeth. Nearly 2.3 million crowns were made annually in the US alone, according to Fortune Business Insights.
But how long do dental crowns last?
While dental crowns are designed to be durable, their lifespan depends on several factors, including the material used, oral hygiene habits, and lifestyle choices.
This article explores what dental crowns are, their expected longevity, and how to extend their lifespan.
What Are Dental Crowns?
A dental crown is a prosthetic device custom-made to fit over a tooth. It is cemented into place to fully encase the visible portion of the tooth above the gum line. Crowns are used in various situations, including:
- Protecting a weakened or cracked tooth
- Restoring a tooth with extensive decay or damage
- Covering a dental implant
- Enhancing the appearance of a misshapen or discolored tooth
- Supporting a tooth with a large filling when little natural tooth structure remains
Dental crowns can be made from different materials, including metal, porcelain, ceramic, resin, or a combination of materials. Each type has unique advantages and affects crown durability factors and aesthetics.
How Long Do Dental Crowns Typically Last?
The dental crown lifespan depends on the type of material used and how well it is cared for. On average:
- Porcelain-Fused-to-Metal (PFM) Crowns: 10 to 15 years
- All-Ceramic or Porcelain Crowns: 10 to 20 years
- Metal Crowns (Gold or Alloy): 20 years or longer
- Resin Crowns: 5 to 10 years
With proper maintenance, some types of dental crowns can last even longer than their estimated lifespan. However, they are not permanent and may eventually need replacement due to wear, damage, or changes in the underlying tooth structure.
Factors Affecting the Longevity of Dental Crowns
1. Material Type
The material used for your crown significantly impacts its durability. Here are some material types to consider.
Metal Crowns - highly durable and less likely to chip or break, making them ideal for back teeth where biting forces are stronger.
Porcelain and Ceramic Crowns - offer a natural appearance but may be more susceptible to chipping, especially if subjected to excessive stress.
Resin Crowns - less expensive but not as durable as other materials and may wear down faster.
2. Oral Hygiene
Maintaining excellent oral hygiene is crucial for preserving both your natural teeth and your crowns. Plaque and bacteria can accumulate around the base of the crown, leading to gum disease or decay in the tooth beneath the crown.
3. Lifestyle and Habits
Certain habits can shorten the lifespan of a dental crown, such as:
- Grinding or clenching your teeth (bruxism)
- Chewing hard objects like ice, pens, or fingernails
- Using teeth as tools to open packages
Wearing a mouthguard at night can protect your crown if you grind your teeth, and avoiding harmful habits helps prevent unnecessary damage.
4. Placement in the Mouth
Crowns on back teeth endure more pressure from chewing. This can lead to faster wear compared to crowns on front teeth.
5. Professional Care
Regular dental check-ups are essential for monitoring the condition of your crown. Your dentist can identify potential issues early, such as cracks, chips, or decay around the crown.
Signs Your Dental Crown Needs Replacement
Even when following crown maintenance tips, dental crowns don't last forever. Be on the lookout for these signs that your crown may need to be replaced.
- Visible Damage: Chips, cracks, or wear on the crown's surface
- Discomfort or Pain: Sensitivity or pain around the crowned tooth could indicate decay, damage, or gum recession
- Looseness: If the crown feels loose or unstable, it may need to be recemented or replaced
- Discoloration: Stains or discoloration on a porcelain crown may affect its appearance
- Gum Problems: Inflammation or recession around the crown could expose the tooth beneath, increasing the risk of decay or infection
How to Extend the Lifespan of Your Dental Crown
While dental crowns are built to last, proper care can significantly extend their longevity. Here are some tips to help keep your crowns in great shape.
1. Practice Good Oral Hygiene
Brush your teeth at least twice a day using fluoride toothpaste and a soft-bristled toothbrush. Floss daily to remove plaque and debris around the base of your crown. Consider using an antibacterial mouthwash to reduce harmful bacteria.
2. Avoid Harmful Habits
Don't chew on hard objects, and avoid using your teeth as tools. If you grind or clench your teeth, talk to your dentist about getting a custom mouthguard.
3. Maintain a Balanced Diet
Limit sugary and acidic foods and beverages, which can weaken the tooth beneath your crown. Instead, focus on a balanced diet rich in fruits, vegetables, lean proteins, and dairy products that promote strong teeth.
4. Attend Regular Dental Check-Ups
Visit your dentist every six months for professional cleanings and examinations. These visits allow your dentist to monitor your crown and address any issues before they become significant problems.
5. Protect Your Teeth During Sports
If you participate in contact sports, wear a protective mouthguard. This will shield your crown and natural teeth from impact.
The Cost of Replacing a Dental Crown
Replacing a dental crown can be an investment, but the cost varies depending on the material and complexity of the procedure. On average, replacing a crown costs between $800 and $3,000 per tooth in the United States.
Factors affecting the cost include the type of crown, the dentist's experience, and whether additional procedures (e.g., a root canal or post and core) are needed.
Dental insurance often covers part of the expense, so check with your provider for details on coverage.
