What are tooth crowns made of? When a tooth is damaged, weak, or decayed, a dental crown acts as a strong protective cap to restore its shape, size, and function. Choosing the right material for your crown depends on various factors, including the location of the tooth, its visibility when you smile, and your personal budget. Dentists use several durable materials today, ranging from porcelain and ceramic to metal alloys and solid gold. Each option offers unique benefits for strength and appearance, ensuring that your smile remains healthy and bright.
What Is A Dental Crown?
A dental crown is a custom-made, tooth-shaped cap that covers the entire visible part of a damaged, weak, or decayed tooth above the gum line. Often called a “cap,” it restores the strength, shape, size, and appearance of a tooth.

What Are Tooth Crowns Made Of?
Dental crowns are made from materials like metal, porcelain, ceramic, zirconia, or composite resin. If you are wondering what are tooth crowns made of, they are typically crafted from materials like:
- Gold and Metal Alloys: Made from gold, nickel, or chromium, these are extremely strong, long-lasting, and ideal for back molars.
- Porcelain-Fused-to-Metal (PFM): Combines a metal base for strength with a tooth-colored porcelain outer layer for a more natural look.
- All-Ceramic or Porcelain: Matches the color and shine of natural teeth closely, making them a top choice for front teeth.
- Zirconia: A very tough type of white ceramic known for high durability and strength, suitable for both front and back teeth.
- Composite Resin: A tooth-colored plastic material typically used for temporary crowns.

What Temporary Dental Crowns Are Made Of?
Temporary dental crowns are made primarily from acrylic resins, bis-acryl composite resins, or pre-fabricated metal/polycarbonate shells. When asking what are tooth crowns made of for temporary use, the answer includes:
- Acrylic Resin: Materials like polymethyl methacrylate (PMMA) or polyethyl methacrylate (PEMA) are affordable, easy to shape at the chairside, and can be color-matched to natural teeth.
- Bis-Acryl Composite: A tooth-colored resin that hardens quickly, shrinks very little during curing, and offers a smooth, aesthetic temporary finish.
- Prefabricated Metals: Stainless steel or aluminum shells are sometimes used for back teeth or molars where appearance matters less and durability is needed for a short period.
- Polycarbonate: Pre-formed tooth-colored plastic shells used as a fast, aesthetic base that is lined with self-curing resin.

Key Criteria For Choosing The Best Dental Crown
Choosing the best dental crown depends on balancing tooth location, durability, aesthetics, and budget. Key Selection Criteria for the Best Dental Crown:
- Tooth Location: Front teeth require high-aesthetic materials like porcelain or ceramic, while back molars need strong materials like zirconia or metal alloys to handle heavy chewing forces.
- Durability and Strength: Zirconia and full-metal or gold options offer maximum resistance to biting pressure and wear. Traditional Porcelain-Fused-to-Metal (PFM) crowns provide a mix of strength and appearance, though porcelain can chip under extreme force.
- Aesthetics: All-ceramic and high-translucency zirconia or porcelain mimic natural tooth color and light reflection best.
- Allergies and Sensitivities: Patients with known metal allergies should avoid base-metal or PFM alloys and select biocompatible ceramic or zirconia alternatives.
- Cost and Insurance: Resin or PFM crowns are generally more budget-friendly, whereas premium all-ceramic and zirconia options carry a higher price tag.

Durability And Lifespan Of Various Crown Materials
Metal and gold alloy crowns last the longest, averaging 20 to 30+ years, while most dental crowns last 10 to 15 years. Different crown materials offer varying levels of durability, appearance, and longevity.
- Metal and Gold (Gold Alloys): Last 20 to 30+ years. It offers unmatched strength, resists heavy chewing forces, and causes very little wear on opposing natural teeth. However, its metallic color makes it best suited for hidden back molars.
- Zirconia: Lasts 15 to 20+ years. This modern material provides extreme durability and fracture resistance while matching the white color of natural teeth. It works well for back teeth and people who grind their teeth.
- Porcelain and Ceramic (e.g., E-max): Lasts 10 to 15 years. These materials look the most like real teeth and match the translucency of natural enamel, making them ideal for front teeth. They are less strong than metal or zirconia and can chip under heavy pressure.
- Porcelain-Fused-to-Metal (PFM): Lasts 10 to 15 years (though some variants wear out in 5 to 10 years). PFM combines a strong metal base with a tooth-colored porcelain surface. Over time, the porcelain top layer can chip or crack, exposing the metal underneath.
- Resin (Composite): Lasts 5 to 10 years as a permanent option. Resin is the least expensive option, but it wears down quickly and breaks or stains much more easily than other materials. Therefore, dentists usually use resin crowns as temporary solutions.

How Crown Materials Affect Your Dental Treatment Cost?
What tooth crowns are made of directly changes the total treatment cost due to raw material expenses, specialized lab work, and fabrication technology.
- Gold and Metal Alloys: Gold-based and precious metal crowns often carry a high price tag due to the cost of the raw metal itself, though they offer unmatched durability for back molars. Standard base-metal alloys can be more affordable, but they lack a natural look.
- Porcelain and Ceramic: These options match the color of natural teeth, making them popular for front teeth. They require detailed aesthetic work from a dental lab, which raises the overall price.
- Zirconia: Known for extreme strength, zirconia bridges the gap between metal durability and tooth-colored aesthetics. Advanced milling technology used to shape it can add to the cost.

FAQs
Can a tooth decay under a dental crown?
Yes, a tooth can decay under a dental crown. While the artificial crown itself cannot get cavities, the natural tooth structure underneath remains vulnerable to bacteria, especially along the gumline.
Are metal dental crowns safe for long term use?
Yes, metal dental crowns are highly safe and durable for long-term use. Made from noble metals like gold or base-metal alloys, they rarely chip, withstand heavy chewing forces, and cause minimal wear.
Does the dental crown procedure hurt?
No, the dental crown procedure does not typically hurt. Dentists use local anesthesia to completely numb the tooth and surrounding area, though you may feel mild sensitivity or soreness afterward.
Which dental crown material looks the most natural?
All-porcelain or solid zirconia dental crowns look the most natural. These materials mimic the translucency, texture, and light-reflecting qualities of real teeth, making them ideal for visible, front-tooth restorations.
Can a porcelain tooth crown be whitened?
No, a porcelain tooth crown cannot be whitened. Traditional whitening gels only work on natural tooth enamel, meaning your crown will permanently maintain its original color after it is fabricated.
