Most people just want their smile to look natural, stay strong, and last without problems, but all those material choices can make things confusing.
In this blog, we’ll break down exactly what tooth crowns are made of, the pros and cons of each material, and how to know which type might be best for your situation. Whether you’re worried about durability, cost, or simply how your smile will look, this guide will give you the clarity you need to feel confident about your next dental decision.
Understanding Dental Crowns
A dental crown is basically a covering that protects a compromised tooth. It restores the tooth’s function, shape, and appearance while also protecting it from further harm. Dentists recommend crowns for issues like severe decay, cracks, fractures, or after root canal treatment. They are also used in dental bridges and implant restorations.
The key factor is the crown material. The choice of what tooth crowns are made of determines not just how they look, but also how long they last and how well they protect your teeth.

Common Materials Used for Dental Crowns
Dentists use a range of materials for crowns. The most common types include porcelain, ceramic, metal alloys, gold, zirconia, and resin-based composites. Each type is suited for specific needs, whether that’s strength for molars, natural appearance for front teeth, or a balance of both.
Let’s look at the most popular options in detail.
Porcelain-Fused-to-Metal (PFM) Crowns
Porcelain-fused-to-metal crowns are one of the most widely used types.They bring together the toughness of metal and the lifelike look of porcelain. The porcelain outer layer matches the shade of natural teeth, while the inner metal core gives durability.
- Pros: Stronger than all-porcelain crowns, good for both front and back teeth, and natural appearance.
- Cons: Over time, the metal may show near the gumline, and they’re not as strong as full metal crowns.
All-Metal Crowns
Metal crowns, often made from alloys like nickel-chromium or cobalt-chromium, are known for their strength. Gold crowns are another version, prized for both durability and biocompatibility.
- Pros: Extremely durable, resistant to fractures, ideal for molars under heavy chewing pressure.
- Cons: Metallic color makes them more noticeable, so they’re less common for front teeth.
Ceramic Crowns
Ceramic crowns are often chosen for front teeth because of their natural look. They are crafted to match the color, size, and shape of surrounding teeth.
- Pros: Excellent aesthetics, metal-free (good for people with allergies), blends well with natural teeth.
- Cons: Less durable than metal-based options, prone to chipping if used on teeth that handle heavy chewing.
Zirconia Crowns
Zirconia crowns are made from zirconium oxide, a durable and biocompatible material. They offer a strong alternative to porcelain and can be layered with porcelain for a more natural appearance.
- Pros: Very durable, tooth-colored, resistant to wear, good for patients who grind their teeth.
- Cons: Slightly less natural-looking than porcelain, may cause wear on opposing teeth if not polished properly.
Composite Resin Crowns
Composite resin crowns are typically more affordable but less durable than other options. They are made from a tooth-colored resin material similar to fillings.
- Pros: Cost-effective, natural appearance, quick to produce.
- Cons: Prone to wear and fractures, shorter lifespan than porcelain or metal crowns.
Temporary Crowns
Before your permanent crown is ready, your dentist may place a temporary crown made of acrylic or stainless steel. These are not designed to last long but protect your tooth until the final crown is cemented.
Factors That Influence Crown Material Choice
Choosing what tooth crowns are made of isn’t just about cost or appearance. Dentists consider several factors:
- Location of the tooth: Molars need stronger materials like metal or zirconia, while front teeth benefit from porcelain or ceramic.
- Bite pressure: Patients who grind their teeth may need stronger materials to avoid fractures.
- Allergies: Some people have sensitivities to metals, making ceramic or zirconia a safer choice.
- Aesthetics: If appearance is a priority, porcelain-based crowns are the go-to.
- Budget: Costs vary widely, with metal crowns often more affordable than porcelain or zirconia.
Longevity of Different Crown Materials
How long do crowns last? It depends heavily on the material:
- Gold and metal crowns: 15 to 20 years or more
- Porcelain-fused-to-metal: 10 to 15 years
- Ceramic: 10 to 15 years
- Zirconia: 10 to 15 years, sometimes longer
- Composite resin: 5 to 7 years
Good oral hygiene, regular dental visits, and avoiding habits like teeth grinding or chewing ice can extend the life of any crown.
Pros and Cons Overview
Here’s a quick summary of crown materials:
- Porcelain-fused-to-metal: Balance of durability and appearance.
- Metal/Gold: Best for strength and longevity.
- Ceramic: Best for aesthetics in front teeth.
- Zirconia: Great mix of strength and appearance.
- Resin: Affordable but less durable.
The Dental Crown Procedure
Getting a crown typically requires two visits. At the first appointment, your dentist prepares the tooth by removing decay and shaping it. Impressions or digital scans are taken, and a temporary crown is placed.
On the second visit, the permanent crown made from your chosen material is fitted and cemented into place. With modern digital scanning and same-day milling technology, some practices can even create crowns in a single appointment.
How to Choose the Right Crown
Ultimately, the best way to decide is by consulting with your dentist. They’ll weigh your tooth’s condition, your bite, your cosmetic goals, and your budget. Together, you can choose the crown material that best suits your needs.
If durability is your top concern, metal or zirconia may be ideal. If you care most about aesthetics, porcelain or ceramic crowns are a better choice.
Final Thoughts
Now that you know the answer to what tooth crowns are made of, you can see that it’s not a one-size-fits-all solution. Each material offers unique benefits, and the right choice depends on your individual needs.
Whether you’re looking for strength, beauty, or an affordable fix, there’s a crown material that fits the bill. Talking with your dentist will give you the confidence to make the best decision for your smile and ensure your new crown serves you well for years to come.
