There is no single best crown for every tooth. The right choice depends on where the crown goes in your mouth, how hard you bite, and whether appearance matters for that spot. Zirconia has become the most versatile option overall, but lithium disilicate (sold as E-max) wins for front teeth, and gold still outlasts everything for back molars if you don’t mind the look.
Crown Materials at a Glance
Five materials account for nearly all dental crowns placed today. Each trades off strength, appearance, and cost differently.
- Monolithic zirconia: Extremely strong ceramic. Handles heavy biting forces well. Newer formulations offer improved translucency, though still not as lifelike as lithium disilicate on front teeth. Costs roughly $1,000 to $2,500.
- Lithium disilicate (E-max): A glass ceramic prized for its translucency and natural light transmission. Pressable versions produce especially vibrant, tooth-like brightness. Less fracture-resistant than zirconia, so it’s best suited to front teeth and premolars under moderate force.
- Porcelain-fused-to-metal (PFM): A metal core covered in porcelain. Stronger than all-porcelain but weaker than zirconia. The main drawback: receding gums can expose a dark metal line at the crown’s edge. Costs $800 to $2,400, averaging around $1,100.
- Gold alloy: Lasts the longest of any crown material and rarely breaks. Gold is gentle on opposing teeth and conforms well to the bite. It’s the least cosmetic option, which is why it’s typically reserved for molars hidden in the back of the mouth. Lifespan can exceed 20 years.
- All-porcelain: Matches natural tooth color closely, making it popular for front teeth. It is, however, the weakest option and has the shortest documented survival rate, with one large study finding just 48% still intact at 10 years compared to 68% for metal crowns.
Best Crowns by Tooth Location
Your front teeth, premolars, and molars face very different demands, so the ideal material shifts as you move through the mouth.
Front Teeth
Appearance is the priority here. E-max is the top recommendation because its glass structure lets light pass through much like natural enamel. Pressable E-max crowns score higher on brightness and color vibrancy than milled versions, producing a result that’s nearly undetectable next to your real teeth. High-translucency zirconia is a reasonable alternative when extra strength is needed, but it still can’t match E-max’s lifelike quality under close inspection.
Premolars
These teeth sit in a transitional zone. They’re visible when you smile, yet they handle moderate chewing forces. Zirconia is the go-to choice here because it balances durability with a clean, tooth-colored appearance. E-max works too, but zirconia provides a wider safety margin against fracture, especially if you clench or grind.
Molars
Strength matters most on back teeth. Monolithic zirconia is the standard modern recommendation. Gold alloy remains an excellent alternative and is arguably the most durable material ever used in dentistry. A study tracking gold crowns found 91% still functioning after 10 years. If cosmetics aren’t a concern, gold is hard to beat.
If You Grind or Clench Your Teeth
Bruxism changes the equation significantly. The repeated, high-force contact from grinding can crack porcelain and chip layered crowns. Monolithic zirconia is nearly always the most practical choice for bruxism patients because it resists fracture under intense lateral forces. Gold alloy is the other strong option, long considered ideal for people with TMJ problems or heavy bites. Both materials hold up far better than PFM or all-porcelain under grinding stress.
E-max, despite its beauty, is riskier for grinders. If you need a crown on a front tooth and you grind at night, your dentist may recommend pairing an E-max crown with a nightguard to protect the investment.
How Much Tooth Gets Removed
Different materials require different amounts of your natural tooth to be shaved down, and this matters. The more tooth structure preserved, the stronger the foundation underneath.
Zirconia and gold crowns are the most conservative. They need only about 0.3 to 0.5 mm of clearance at the gum line and roughly 1 to 1.5 mm shaved off the biting surface. That’s noticeably less than other options. PFM crowns require 1.0 to 1.5 mm at the margin and up to 2.5 mm off the top to accommodate both the metal core and the porcelain layer. All-ceramic and E-max crowns fall in between, needing about 0.8 to 1.0 mm at the edges and 2 mm off the biting surface.
If your tooth is already weakened or has limited structure remaining, zirconia or gold may be the better choice simply because they preserve more of what’s left.
Wear on Opposing Teeth
A crown doesn’t just need to survive. It also needs to be kind to the teeth it bites against. In lab testing, gold and zirconia crowns caused virtually identical, minimal wear on opposing surfaces, losing only about 0.01 cubic millimeters of material during testing. Natural enamel biting against zirconia lost far more, around 0.47 cubic millimeters. This means zirconia is hard-wearing but can be abrasive to the teeth it contacts. Gold, by contrast, is both durable and gentle.
If the tooth opposite your crown is already worn down or has its own restoration, gold is the safest bet for protecting it. Polished zirconia performs reasonably well, but rough or unglazed zirconia can accelerate enamel wear on the other side.
Metal Allergies and Gum Health
PFM and base-metal crowns contain nickel, chromium, or other alloys that occasionally trigger allergic reactions, inflammation, or gum sensitivity. If you’ve ever reacted to costume jewelry or metal watchbands, you may be at higher risk. Zirconia and E-max are completely metal-free and well tolerated by gum tissue, making them the clear choice for anyone with known metal sensitivities or autoimmune conditions. Gold alloys are also highly biocompatible, with allergic reactions being exceptionally rare.
Same-Day Crowns vs. Lab-Made Crowns
Many dental offices now offer same-day crowns using in-office milling machines (often called CEREC systems). The appeal is obvious: one appointment instead of two, no temporary crown, no two-week wait. The machine scans your tooth digitally and carves the crown from a ceramic block while you sit in the chair.
The tradeoff is material range. Same-day systems typically mill from ceramic or zirconia blocks, but they can’t produce PFM or gold crowns. Lab-made crowns also tend to offer better coverage when a fracture extends below the gum line, since the in-office scanner sometimes struggles to capture that area accurately. For straightforward crowns on premolars or front teeth, same-day options work well. For molars under heavy load, a lab-fabricated crown may still be the stronger choice.
Putting It All Together
For most people getting a crown on a back molar, monolithic zirconia offers the best combination of strength, reasonable aesthetics, and tooth preservation. For a visible front tooth, E-max delivers the most natural-looking result. Gold remains the longevity champion for anyone who prioritizes function over appearance. PFM crowns, once the default, have largely been overtaken by zirconia, which matches or exceeds their strength without the dark-line-at-the-gumline problem.
The “best” crown is ultimately the one matched to the specific tooth, your bite habits, and what you value most. A crown that looks perfect but cracks in two years wasn’t the right choice, and neither is one that lasts decades but makes you self-conscious every time you smile.
