If you have been told you need a dental crown, you may have wondered why your dentist is asking you to choose between materials. Two of the most common options today are zirconia crowns and porcelain crowns. Both can restore a damaged tooth, but they are not the same, and the right choice depends on your specific situation.
At Bloomington Family Dental, Dr. Brian Gray takes the time to explain your options clearly, with no pressure and no unnecessary upsells. This guide breaks down the key differences in dental crown materials so you can walk into your appointment feeling confident.
What Is a Dental Crown?
A custom-fitted dental crown is a cap placed over a damaged, decayed, or weakened tooth to restore its shape, size, function, and appearance. Dental crowns are commonly used to:
● Protect a tooth after a root canal
● Repair a cracked or broken tooth
● Cover a severely worn-down tooth
● Support a dental bridge
● Complete a dental implant
The material your dentist uses for your crown affects how it looks, how strong it is, and how long it will last. That is why understanding dental crown materials matters before you commit to treatment.
What Are Zirconia Crowns?
Zirconia crowns are made from zirconium dioxide, a material that is known for its exceptional strength and biocompatibility. They have grown rapidly in popularity over the past decade and are now one of the most widely placed types of dental crowns.
Key features of zirconia crowns:
- Strength: Zirconia is significantly stronger than porcelain, making it well suited for back teeth that endure the heaviest chewing forces.
- Durability: With proper care, zirconia crowns can last 15 years or longer. Some are considered nearly unbreakable under normal chewing conditions.
- Appearance: Modern zirconia crowns are designed to mimic the translucency of natural teeth, though some earlier versions had a more opaque look.
- Biocompatibility: Zirconia is metal-free and does not trigger allergic reactions, making it a good choice for patients who are sensitive to metals.
- Teeth grinding: Because of their strength, zirconia crowns are particularly suitable for patients who grind or clench their teeth.
What Are Porcelain Crowns?
Porcelain crowns, including porcelain-fused-to-metal (PFM) options, have been used in dentistry for decades. They are highly regarded for their ability to closely replicate the natural look of teeth.
Key features of porcelain crowns:
- Aesthetics: Porcelain has a natural translucency that blends well with surrounding teeth, making it the preferred choice for visible front teeth.
- Appearance over time: Traditional PFM crowns may develop a thin grey line near the gumline over time as gums recede and the metal base becomes visible.
- Durability: Porcelain crowns typically last between 10 and 15 years and are somewhat more prone to chipping under heavy pressure compared to zirconia.
- Cost: Porcelain and PFM crowns are generally less expensive upfront, though the long-term value depends on how well they hold up.
Zirconia vs Porcelain Crowns: Side-by-Side Comparison
| Feature | Zirconia Crowns | Porcelain Crowns |
|---|---|---|
| Strength | Very high | Moderate |
| Aesthetics | Good to excellent | Excellent |
| Lifespan | 15+ years | 10-15 years |
| Best for | Back teeth, grinders | Front teeth |
| Metal-free | Yes | Depends on type |
| Cost | Higher upfront | Lower upfront |
Which Dental Crown Material Is Right for You?
There is no single answer that applies to every patient. Here are a few general guidelines:
Choose zirconia crowns if:
● The crown is being placed on a molar or back tooth
● You grind or clench your teeth at night
● You want a long-lasting, low-maintenance restoration
● You have a metal sensitivity or allergy
Choose porcelain crowns if:
● The crown is for a front tooth where natural appearance is the priority
● A highly lifelike aesthetic is your main concern
● Your biting forces are not unusually heavy
The best way to decide is to have a direct conversation with your dentist. Dr. Brian Gray at Bloomington Family Dental reviews your bite, tooth location, and lifestyle before making any recommendations. You will never be pushed toward a more expensive option if it is not genuinely the right fit.

How Are Dental Crowns Placed?
Regardless of the material, the process for getting a crown usually follows a similar pattern. Dr. Gray will examine the tooth, take digital impressions or scans, and send the specifications to a dental lab. A temporary crown safeguards the tooth while your permanent one is being made. On your second visit, the permanent crown is fitted, adjusted for your bite, and cemented into place.
Some practices can place same-day crowns using in-office milling technology, which removes the need for a temporary crown and a return appointment.
Caring for Your Crown
Whether you choose zirconia or porcelain, the care routine is the same as for natural teeth: brush twice daily, floss around the crown margin, and keep up with regular preventive checkups. Avoiding very hard foods and using your teeth as tools for any purposes, like tearing a packet of chips, will help extend the life of any crown.

Frequently Asked Questions
Are zirconia crowns better than porcelain crowns?
It depends on your situation. Zirconia crowns are stronger and more durable, making them a better choice for back teeth or patients who grind their teeth. Porcelain crowns offer a more natural, translucent appearance and are often preferred for front teeth. Neither material is universally better — the right choice depends on the tooth location, your bite, and your aesthetic goals.
How long do zirconia crowns last?
With proper care, zirconia crowns can last 15 years or longer. Because of their exceptional strength, they are less prone to chipping or cracking compared to porcelain, which can extend their lifespan significantly when placed on back teeth.
Do zirconia crowns look natural?
Yes. Modern zirconia crowns are designed with improved translucency to closely mimic the look of natural teeth. Earlier versions had a more opaque appearance, but today’s options are a significant improvement in aesthetics.
Are porcelain crowns safe?
Yes, porcelain crowns are safe and biocompatible. All-porcelain crowns contain no metal, making them a good option for patients with metal sensitivities. Porcelain-fused-to-metal crowns do contain a metal base, which is worth discussing with your dentist if you have known allergies.
Which dental crown material is best for back teeth?
Zirconia is generally the preferred dental crown material for back teeth because of the higher chewing forces in that area. Its strength and durability make it much better suited for molars than porcelain, which is more susceptible to chipping under pressure.
Can a dental crown fall off?
It is uncommon but possible. A crown can loosen if the cement breaks down over time, if the tooth underneath develops decay, or if the crown is subjected to excessive force. If your crown feels loose or falls out, call your dentist promptly to have it re-cemented or replaced.
How much do zirconia crowns cost compared to porcelain crowns?
Zirconia crowns typically cost more upfront than porcelain or PFM crowns. However, their longer lifespan and lower likelihood of needing replacement can make them a better long-term investment depending on the tooth. Your dentist can provide a specific estimate based on your treatment plan and insurance coverage.
