Dental crowns are made from four main categories of material: metal alloys (including gold), porcelain (ceramic), porcelain fused to metal, and newer materials like zirconia. The right choice depends on where the crown sits in your mouth, how much force your teeth generate, and how natural you want it to look. Costs range from $500 to $3,000 per tooth depending on the material.
Gold and Metal Alloy Crowns
Gold crowns have been used longer than any other type, and they remain the most durable option available. A gold crown isn’t pure gold. It’s an alloy, meaning it’s mixed with other metals to add strength. The best versions, called high-noble alloys, contain at least 60% precious metals like gold, platinum, palladium, and silver. These metals are chosen because they resist corrosion and rarely cause reactions in the mouth. Noble alloys contain at least 25% precious metal, while non-noble (base metal) alloys use less than 25%.
Gold’s biggest advantage is longevity. Studies show a 95% survival rate over 10 years, and with good care, gold crowns can last for decades. Gold is also gentle on the teeth it bites against, unlike harder materials that can wear down opposing enamel. It stays strong even when thin, which means your dentist can preserve more of your natural tooth during preparation. The obvious drawback is appearance: gold crowns are visible when you smile or open your mouth, which is why they’re typically placed on back molars where strength matters more than looks.
All-Porcelain (Ceramic) Crowns
Porcelain crowns offer the most natural appearance because they mimic the translucency and color of real teeth. They don’t conduct heat or cold efficiently, so you may experience less sensitivity to hot and cold foods right after placement. But porcelain has a contradictory nature: it’s harder than tooth enamel, yet it can be brittle. Under repeated pressure, especially from clenching or grinding, it can fracture.
To compensate for that brittleness, porcelain crowns need to be thicker than gold ones. That means more of your healthy tooth has to be removed during preparation. Pure porcelain crowns work best on front teeth, where bite forces are lower and appearance is the priority. For people who grind their teeth, porcelain alone is generally not the best choice for molars.
Zirconia Crowns
Zirconia has become one of the most popular crown materials in recent years. It’s a white crystalline material made from the metal zirconium, and it sits in a sweet spot between the strength of metal and the appearance of porcelain. Zirconia’s flexural strength is roughly 1,000 MPa, more than twice that of other ceramics, making it exceptionally resistant to cracking under pressure.
Zirconia can be tinted to match your natural teeth and has some translucency, though it’s noticeably less translucent than other ceramics. The most translucent zirconia available is only about 73% as translucent as lithium disilicate (another popular ceramic). That slight opacity actually helps when a crown needs to mask a darkened or damaged tooth underneath. With proper care, zirconia crowns last 10 to 15 years or longer, and they’re considered an excellent choice for molars because they handle heavy biting forces well.
Lithium Disilicate Crowns
Lithium disilicate is a glass-ceramic material often sold under brand names you might hear at your dentist’s office. It has a flexural strength around 400 MPa, which is strong enough for most situations but not as resilient as zirconia. Where it excels is aesthetics. Its high translucency makes it look remarkably lifelike, which is why it’s a popular choice for front teeth. These crowns also last 5 to 15 years or longer with proper care. For back teeth in someone who clenches or grinds, zirconia is typically the safer bet.
Porcelain Fused to Metal (PFM) Crowns
PFM crowns layer porcelain over a metal frame to combine the appearance of ceramic with the strength of metal. The metal base provides a safety net: even if the porcelain chips, the underlying structure still protects your tooth. These crowns cost between $800 and $1,400 per tooth, making them a mid-range option.
The trade-off is a cosmetic one. The metal underneath requires a layer of opaque porcelain to hide its grayish color, which blocks some of the natural translucency you’d get from an all-ceramic crown. Over time, as gums recede, a thin dark line can appear at the base of the crown where the metal edge becomes visible. When the metal base is a gold alloy, the bond between porcelain and metal is weaker than with zirconia, meaning the porcelain is more likely to chip away over the years. PFM crowns generally last 5 to 15 years.
How Crowns Are Made Today
Most permanent crowns are now designed and manufactured digitally. Your dentist takes a digital scan of the prepared tooth, and software creates a 3D model of the crown. That design is then sent to a milling machine that carves the crown from a solid block of material, whether zirconia, lithium disilicate, or another ceramic. Some offices have in-house milling equipment that can produce a crown in a single visit, while others send the design to an outside lab.
While your permanent crown is being fabricated, you’ll wear a temporary crown. These are made from acrylic or bisacrylic resin, sometimes produced by a 3D printer. Temporary materials are softer, more porous, and more prone to plaque buildup than any permanent crown material. They’re designed to last weeks, not years, which is why getting your permanent crown placed on schedule matters.
Choosing a Material by Tooth Location
The teeth in the back of your mouth absorb the highest bite forces, so molars need crown materials that won’t crack under pressure. Zirconia and gold alloys are the strongest options for molars. Gold is especially well suited for people who clench or grind their teeth because it absorbs force without damaging opposing teeth. Zirconia is a good alternative when you want something strong that also looks tooth-colored.
Front teeth don’t bear as much force, so the priority shifts to appearance. Lithium disilicate and high-quality porcelain produce the most lifelike results here because of their translucency. For teeth in the middle of the mouth, where both strength and appearance matter, zirconia or porcelain-fused-to-zirconia crowns offer a reasonable balance.
Metal Allergies and Biocompatibility
Base-metal crowns containing nickel, cobalt, or chromium can trigger allergic reactions in some people. Nickel allergy is the most common, affecting roughly 23% of people tested in one study, with women more frequently affected than men. Symptoms can include gum inflammation and tissue irritation around the crown.
Gold alloys cause far fewer reactions than base metals, and titanium alloys are the most biocompatible metal option, showing almost no difference from healthy tissue in studies measuring immune response. If you have a known metal sensitivity, all-ceramic crowns (zirconia or lithium disilicate) eliminate the risk entirely, since they contain no metal. When patients develop confirmed allergies to existing metal crowns, the standard approach is removing the metal restoration and replacing it with a ceramic one.
Cost Comparison by Material
As of 2025, crown prices vary widely depending on the material, your location, and the complexity of the work:
- Porcelain (all-ceramic): $800 to $3,000 per tooth
- Porcelain fused to metal: $800 to $1,400 per tooth
- Gold and metal alloys: $800 to $2,500 per tooth
Gold crowns fluctuate with the price of precious metals, so their cost can swing more than other types. All-ceramic crowns sit at the widest price range because the category includes both basic porcelain and premium materials like zirconia and lithium disilicate. Dental insurance typically covers a portion of crown costs, though many plans cap their contribution based on the least expensive adequate material.
