Types of Dental Crowns: Materials, Cost & How to Choose

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

A dental crown is a custom cap that covers a damaged, weakened, or heavily restored tooth to rebuild its shape, strength, and appearance. While every crown does the same basic job, the material it is made from changes almost everything else: how natural it looks, how long it lasts, how much it costs, and which tooth it suits best. Understanding the main types of dental crowns makes it far easier to have an informed conversation with your dentist and feel confident about the recommendation you receive.

Below we break down each crown material with its real tradeoffs, then compare them by durability, esthetics, cost, ideal location, and biocompatibility so you can see how the choices stack up side by side.

What a dental crown does and why material matters

Crowns are used after a large filling fails, following root canal treatment, to protect a cracked tooth, to restore a dental implant, or to improve the look of a discolored or misshapen tooth. Because a crown fully encases the visible tooth, it takes on all the biting forces that tooth handles every day. A molar can absorb hundreds of pounds of chewing pressure, while a front tooth is seen every time you smile. That is why no single material is best for every situation.

When dentists weigh crown materials, they are really balancing five things: strength, esthetics, how gentle the material is on the opposing teeth, biocompatibility, and cost. The rest of this guide walks through each material with those factors in mind. If you also want a step-by-step look at the appointment itself, see our guide to the dental crown procedure.

All-porcelain and all-ceramic crowns

All-porcelain and all-ceramic crowns are the top choice when appearance matters most. Because they contain no metal, light passes through them much like it does through natural enamel, giving a lifelike translucency that is hard to distinguish from a real tooth. This makes them a favorite for front teeth and for anyone with a highly visible smile line.

The tradeoff is strength. Traditional feldspathic and glass-ceramic porcelains are more prone to chipping or fracturing than metal or zirconia, especially under heavy grinding. They are an excellent esthetic option but are usually reserved for teeth that do not take extreme force, or paired with a nightguard if you clench. Patients weighing a crown against a more conservative cosmetic option may also want to read veneers vs crowns.

E-max lithium disilicate crowns

E-max is a specific type of all-ceramic crown made from lithium disilicate, a glass-ceramic that is considerably stronger than older porcelains while keeping outstanding esthetics. It has become one of the most popular choices for front teeth and premolars because it delivers a natural look with meaningfully better fracture resistance. E-max can be milled as a single solid piece or pressed, and it bonds strongly to the underlying tooth, which adds to its durability.

Zirconia crowns

Zirconia is a ceramic, but a very different one. It is exceptionally strong and fracture-resistant, which makes it the go-to material for molars and for patients who grind their teeth. There are two main styles. Monolithic zirconia is milled from a single solid block and is nearly unbreakable, though older, more opaque versions can look slightly flat. Layered zirconia adds a porcelain overlay on top of a zirconia core for better esthetics, at the cost of a small chipping risk in that outer layer.

Modern high-translucency zirconia has narrowed the esthetic gap considerably, so it is increasingly used on visible teeth as well. Zirconia is also highly biocompatible and metal-free, which appeals to patients with metal sensitivities. Its main downside is that it is hard on the opposing teeth if not polished well, and its strength can make it slightly harder for a dentist to adjust or remove.

Porcelain-fused-to-metal (PFM) crowns

PFM crowns were the workhorse of dentistry for decades and are still widely used. They combine a metal substructure for strength with a porcelain outer layer for a tooth-colored appearance, offering a solid balance of durability and esthetics at a moderate cost. They work well on both front and back teeth and are a reliable choice for bridges.

The classic drawback is the metal margin. Over time, or if the gums recede, a thin dark line can become visible at the gumline, which is why pure ceramic options are often preferred for the most visible front teeth. The porcelain layer can also chip, exposing the metal underneath. Even so, PFM remains a dependable, cost-effective option. PFM is also a common material for a dental bridge.

Gold and metal alloy crowns

Gold and other metal-alloy crowns are the most durable option of all. They almost never chip or crack, they wear at a rate similar to natural enamel so they are gentle on the opposing teeth, and they require the dentist to remove less tooth structure to place them. They also seal extremely well against leakage and can last for decades.

The obvious limitation is color. A gold crown looks like metal, so it is rarely chosen for front teeth. It shines, however, on out-of-sight molars, for patients who clench heavily, and where longevity is the top priority. Modern gold crowns are usually an alloy of gold with other metals for added hardness, and they are highly biocompatible for most people.

Same-day CEREC crowns vs traditional lab crowns

Crown fabrication comes in two workflows. Traditional lab crowns involve a digital or physical impression that is sent to a dental laboratory, a temporary crown worn for a couple of weeks, and a second visit to cement the final restoration. This route allows the widest range of materials, including layered zirconia and highly customized esthetics.

Same-day systems such as CEREC scan the tooth, design the crown on a computer, and mill it from a ceramic block in the office, so you leave with the permanent crown in a single visit. Same-day crowns are typically milled from monolithic ceramics like E-max or zirconia. They are convenient and skip the temporary, though extremely complex esthetic cases on front teeth may still be handled better by a skilled lab technician.

How to choose the right crown

Your dentist weighs several factors before recommending a material. The tooth’s position is central: front teeth favor esthetic ceramics like E-max or all-porcelain, while molars favor strength from zirconia or gold. A heavy grinder needs a tough, fracture-resistant material. Metal sensitivities point toward metal-free ceramics. Budget and insurance coverage also play a part, as does whether you want the convenience of a single visit.

• Durability: gold and monolithic zirconia lead, followed by E-max and PFM, with traditional all-porcelain the most chip-prone.
• Esthetics: all-porcelain and E-max look most natural, high-translucency zirconia is close behind, PFM is good but risks a dark margin, and gold is the least tooth-like.
• Best location: front teeth suit ceramics, back teeth suit zirconia or gold, and PFM works reasonably in both.
• Biocompatibility: zirconia and all-ceramic are metal-free, gold alloys are well tolerated by most, and PFM may not suit patients with metal allergies.

Cost, insurance, and lifespan

Crown costs vary widely by material and region, but as a rough guide, expect roughly $800 to $1,500 for a PFM crown, $1,000 to $2,500 for zirconia or all-ceramic and E-max, and $1,000 to $2,500 or more for a gold crown depending on the gold price. Dental insurance often covers around half the cost of a medically necessary crown after any deductible, though purely cosmetic upgrades may not be covered. For a deeper breakdown, see how much a dental crown costs.

With good oral hygiene and regular checkups, most crowns last about 10 to 15 years, and many gold and zirconia crowns last far longer. When only part of a tooth needs coverage, a more conservative restoration may be appropriate instead of a full crown; our guide on a dental inlay vs onlay explains when that applies. Ultimately, the best crown is the one matched to your specific tooth, bite, appearance goals, and budget, which is exactly the conversation to have with your dentist.
