Which Crown Material Should I Choose: Zirconia, Porcelain or Gold, and How Long Does Each Last?

What crown materials are available?

A dental crown is a cap that covers and protects a damaged tooth. Four materials are common. Zirconia is a very strong white ceramic. Porcelain-fused-to-metal (PFM) is a metal shell with a porcelain coat. All-ceramic crowns, such as lithium disilicate (a glass-ceramic), are tooth-colored throughout. Gold alloy is a metal. Each trades strength, looks and tooth wear differently.

Crowns can also be monolithic, made as one solid piece, or layered, with a strong core and a different material fired on top. Layered designs look more natural in some cases, but the added layer can chip. This matters when you read the research below.

How do the four materials compare?

Zirconia and gold are described as very durable, all-ceramic crowns as the most natural looking, and PFM sits in between. No material wins on every point, which is why dentists match the material to the tooth. The table below summarizes what the ADA, Cleveland Clinic and published reviews report.

Sources: ADA, 2025; Cleveland Clinic, 2023; Rosa et al., 2026. The 2026 wear meta-analysis pooled 9 clinical studies in 203 patients, with follow-up of 6 to 24 months. It found significant wear of opposing enamel for monolithic zirconia and for lithium disilicate. Metal-ceramic crowns with feldspathic veneering did not show significant wear, but the studies varied widely. Treat the comparison as preliminary.

How long does each crown material last?

Cleveland Clinic gives an average crown lifespan of 5 to 15 years and says crowns can last upwards of 30 years with proper care. Studies track survival, meaning the crown is still in function. Five-year survival is high and close together for the main materials. Study design and definitions differ, so treat these numbers as estimates.

In the 2026 review, feldspathic ceramic, glass-infiltrated alumina and veneered leucite or lithium disilicate crowns had significantly lower survival than monolithic lithium disilicate. Monolithic lithium disilicate and zirconia crowns had significantly fewer ceramic fractures and less chipping than layered versions (Pjetursson et al., 2026).

An older 2015 review found that zirconia crowns were more often lost to fracture of the veneering ceramic and had more loss of retention than metal-ceramic crowns. Zirconia also survived less well in back teeth, and the review advised against making them a primary option (Sailer et al., 2015). The 2026 review reached a more favorable view, and the ADA says long-term evidence for zirconia is still limited.

Two cautions apply. Five years is short for something meant to last decades. And the gold figures come from one practitioner's cast gold restorations, which included inlays, onlays and partial crowns as well as full crowns, so they show potential, not a promise.

Can a chipped crown be repaired?

Sometimes. Small chips in the porcelain layer of a layered crown can occasionally be smoothed or patched in the mouth. A crown that cracks through usually needs replacing, and Cleveland Clinic notes a damaged crown may need replacement sooner. Gold and monolithic crowns have no separate porcelain layer to chip, though any crown can still crack or wear.

If you notice a rough edge, a dark line at the gum, a bite that feels high, or pain when you chew, call your dentist rather than waiting. Our post on tooth pain after a filling or crown explains common causes.

Which crown material fits which tooth and habit?

Start with the job the tooth does, then add your habits and then color. Back teeth take heavy chewing forces, so strength matters most. Front teeth show when you smile, so appearance matters more. Grinding adds load to any material, so tell your dentist if you grind or clench.

Do I need a night guard to protect a crown?

A night guard may help if you grind or clench, but only an exam can tell. Cleveland Clinic advises asking your dentist about a custom mouth guard if you grind. The ADA says ceramics may fracture without warning when flexed excessively, and grinding adds load to any crown.

MouthHealthy lists chipped or cracked teeth and worn, damaged spots along tooth edges as signs of grinding. It says a custom guard made from a mold of your teeth gives the closest, most comfortable fit, and store-bought guards may not protect as well (ADA MouthHealthy, 2026). That page does not say a guard stops the grinding. It protects teeth and dental work.

Material and design matter too. In the 2026 crown review, monolithic designs had fewer fractures and chips than layered ones, so ask whether one suits your tooth. If jaw soreness or headaches come with grinding, ask about our TMJ evaluation and treatment.

How do I decide? Questions to ask at your exam

Use one rule of thumb: choose for the tooth's job first, your habits second and color last. Then ask your dentist about each of these questions before agreeing to a material. The answers show whether a material was chosen for your tooth or just by habit.

1. Where is this tooth, and how hard does it chew?

2. Do I grind or clench, and would a night guard help?

3. How much healthy tooth is left to support the crown?

4. Is a monolithic or layered design planned, and why?

5. How will the crown be adjusted so it does not overload the tooth that bites against it?

6. If it chips or the bite changes, what are my repair or replacement options?

If you are also weighing a thin shell instead of a full cap, our comparison of veneers vs crowns explains the difference. To learn how same-day crown technology works, read our post on same-day dental crowns and ask whether it suits your tooth. You can also see our crowns and bridges and cosmetic crowns pages.

How we approach this at Gardens

At Gardens Implant & Cosmetic Dentistry, the material depends on the tooth, your bite and your goals, so we do not pick one before an exam. Dr. Hans Almanzar, DDS, checks how much healthy tooth remains, where the tooth sits, how your teeth fit together, and whether there are signs of grinding.

We also review gum health, existing dental work, any metal allergy and how visible the tooth is, and we use X-rays to check the roots and the bone. Then we explain the options that fit and the trade-offs of each. Ask us which options we use for your case. Cost and timing are reviewed with you at the visit.

When should I call right away?

Call promptly if a crown comes loose or falls off, if the tooth under it hurts, or if the crown cracks. Seek urgent care for facial swelling, a pimple on the gum, fever, or trouble swallowing or breathing. A lost crown leaves the tooth exposed, so keep the crown and avoid chewing on that side until you are seen.

Frequently asked questions

How long does a dental crown usually last?

Cleveland Clinic gives an average lifespan of 5 to 15 years and says crowns can last upwards of 30 years with proper care and maintenance. Material matters, but so do decay at the crown edge, grinding and your cleaning habits. Regular exams help catch problems before a crown fails.

Is zirconia stronger than porcelain-fused-to-metal?

Zirconia is a very strong ceramic. The ADA reports high flexural strength of 900 MPa or more. Strength is not the only factor, though. In a 2026 meta-analysis, pooled five-year survival was similar for monolithic zirconia (96.8%) and metal-ceramic crowns (97.1%), so both can perform well.

Do gold crowns still make sense today?

For some back teeth, yes. Cleveland Clinic says metal crowns rarely chip or break, last the longest in terms of wear, and need only a small amount of enamel removal. The main drawback is the metallic color, so gold is usually considered for teeth that are not visible when you smile.

Can a crown wear down the teeth that bite against it?

It can. A 2026 meta-analysis found that monolithic zirconia and lithium disilicate caused more wear to opposing enamel than enamel against enamel, though follow-up was short and results varied. Cleveland Clinic calls zirconia gentle on opposing teeth, so the evidence is mixed. Ask your dentist how the crown will be finished and checked.

Do I need a night guard if I get a crown?

Ask. Cleveland Clinic advises that if you grind or clench your teeth, you should ask your dentist about a custom mouth guard. The ADA says ceramics may fracture without warning when flexed excessively, and grinding adds load. A guard can help protect both the crown and your teeth.

What if I have a metal allergy?

Tell your dentist before the crown is planned. Cleveland Clinic says all-ceramic crowns suit people with metal allergies, and zirconia is a ceramic rather than a metal alloy. Your dentist can review the materials involved, including any metal framework, and choose with your allergy in mind.
