Types of Dental Crowns UK: Materials, Costs, and Which Lasts Longest

Do you know what's great about dental crowns in 2026? Every single material on the table is a good one. That wasn't always true.

Go back a couple of decades and crown selection involved real trade-offs and real compromises, with dentists having to choose which kind of failure mode they'd rather their patients live with. Now? The materials are all predictably excellent. The conversation has shifted from "which one won't let me down" to something much more interesting: which material is the perfect fit for this specific tooth, in this specific mouth, doing this specific job.

And the materials themselves are really cool (yes, even to non-dentists). Ceramics that let light pass through them like real enamel. A metal so biocompatible it wears at exactly the same rate as natural teeth. An engineered ceramic so strong that fractures are rare enough to make dental journals when they happen. Each one has a personality, a set of strengths that make it the obvious choice in certain situations.

At UrgentCare Dental, dental crowns are £650, and the material choice is part of the consultation. We'll talk through which tooth needs crowning, what kind of forces it sees, and what'll give you the best long-term result.

Porcelain (All-Ceramic) Dental Crowns

Porcelain crowns are made entirely from ceramic, with no metal core. And what makes them special is genuinely beautiful: the ceramic gets layered in different opacities and shades to replicate the translucency, depth, and colour variation of natural enamel.

Think about what that means. Light passes through a porcelain crown the way it passes through a natural tooth. That translucency, that glow, is what makes them look real. In the right light, a well-made porcelain crown is completely indistinguishable from the natural teeth around it. That makes porcelain the natural choice for front teeth and premolars: any tooth that shows when you smile.

The trade-off is strength. Modern ceramics (lithium disilicate, specifically) are significantly stronger than earlier porcelain materials, but they can still chip or fracture under heavy biting forces, particularly if the patient grinds their teeth. They're not the first choice for a molar that takes the full force of chewing.

The weak point is usually chipping at the edges rather than catastrophic failure, and most porcelain crowns last 10-15 years, with many going longer. Across the UK, they cost £400-£800. At UrgentCare Dental, it's £650.

Zirconia Dental Crowns

Zirconia is the material that's changed crown dentistry over the last decade. It's a ceramic, technically (zirconium dioxide), but it behaves more like a very refined metal: enormously strong, highly wear-resistant, and biocompatible.

The strength numbers tell a striking story. Zirconia has a flexural strength of 900-1,200 MPa, compared to 300-400 MPa for lithium disilicate porcelain and 100-150 MPa for traditional porcelain. In practical terms: a zirconia crown is almost impossible to break under normal biting forces. Fractures are rare enough to be case-study material when they do happen.

Early zirconia crowns had an aesthetic problem, though, and it was a memorable one: they were opaque. That bright, uniform whiteness that looked obviously artificial, like a tooth made of bathroom tile.

Modern zirconia is so much better that it doesn't even look like the same material at all. Multi-layered zirconia blanks now incorporate translucency gradients that mimic natural enamel, with more opaque dentin shades at the base and translucent enamel shades at the biting edge. The transformation from those early bathroom-tile crowns to what's available now is one of the genuinely impressive material science stories in modern dentistry.

The result is a crown that combines zirconia's extraordinary strength with aesthetics that approach (though don't quite match) all-ceramic crowns. For most teeth, modern zirconia is visually indistinguishable from the natural teeth around it.

That combination makes zirconia the default choice for molars and premolars, where strength matters most. It's also increasingly popular for front teeth, where the latest translucent formulations deliver both beauty and durability. For patients who grind their teeth, zirconia's fracture resistance is a genuine game-changer: it's virtually fracture-proof under normal and even excessive biting forces.

Longevity matches the strength. Zirconia crowns last 15-20+ years, and the material itself shows no signs of degradation within normal crown lifespans. When a zirconia crown eventually needs replacing, it's usually because of changes in the surrounding tooth or gum, not failure of the crown itself. Across the UK, zirconia costs £500-£900. Some practices charge a premium over porcelain; others price them the same.

Porcelain-Fused-to-Metal (PFM) Dental Crowns

PFM crowns have an interesting place in dental history. For decades, they were the crown. A metal core (usually cobalt-chromium or gold alloy) covered with a layer of porcelain for aesthetics. Metal for strength, porcelain for appearance. It was a clever piece of engineering, and it dominated dentistry for a very long time.

And millions of them are still going strong. PFM crowns placed 10, 15, even 20 years ago are sitting in mouths across the UK right now, functioning perfectly. That track record is real, and it matters. The combination of metal strength and porcelain aesthetics was the best available option for most of modern dentistry's history, and "best available for decades" is a serious credential.

Where PFM crowns show their age is at the gum line. The metal core creates a dark shadow where the crown meets the gum: a greyish line that becomes more visible as gum tissue thins or recedes with age. On front teeth, this dark margin can be cosmetically significant. On back teeth, it's rarely noticed. The metal core also blocks light, which prevents the translucency that makes all-ceramic and zirconia crowns look so natural. A PFM crown looks like a tooth from arm's length, but up close, it lacks the depth and vitality of metal-free alternatives.

Zirconia has gradually taken over PFM's territory, offering comparable strength without the metal core and its aesthetic compromises. But PFM still has its loyalists for good reason: back teeth where aesthetics are secondary, long-span bridges where the metal framework provides structural support, and patients with strong bites who need maximum durability.

That metal core, by the way, is virtually unbreakable. The porcelain overlay can chip, but the underlying crown remains functional, and chips can sometimes be repaired without replacing the entire crown. That gives PFM crowns a lifespan of 10-20 years, with the metal core comfortably outlasting the porcelain. Cost is £400-£800 across the UK, generally similar to all-ceramic crowns.

Gold and Metal Alloy Dental Crowns

Full metal crowns, particularly gold alloy crowns, have been used in dentistry for over a century. They're the least aesthetically appealing option (they look like metal, because they are metal), but they have properties that no other material matches.

Gold alloy has a wear rate almost identical to natural enamel. This matters because a crown that's harder than enamel (like zirconia or porcelain) can wear down the opposing tooth over time. Gold wears at the same rate as the tooth it bites against, creating a harmonious relationship between crown and opposing tooth that preserves both.

Gold crowns require the least tooth preparation: the metal can be made thinner than porcelain or zirconia while retaining its strength. Less tooth preparation means more natural tooth structure is preserved, which benefits the tooth's long-term health.

The fit of a gold crown is exceptional. The gold alloy can be burnished (shaped under pressure) to adapt intimately to the prepared tooth surface, creating a seal at the margin that's tighter than any other crown material achieves. That seal reduces the risk of bacteria getting between crown and tooth, which reduces the risk of decay under the crown.

All of this makes gold the quiet champion for second and third molars: far back teeth where aesthetics are irrelevant and function is everything. Gold doesn't fracture. It flexes slightly under load and returns to shape, absorbing forces that would crack porcelain. And the longevity numbers are remarkable: 20-30+ years is standard, with gold crowns routinely outlasting every other crown type. Some gold crowns placed in the 1970s and 1980s are still functioning perfectly today.

The cost is £500-£1,200 across the UK, influenced by the current gold price. The precious metal content adds upfront cost, but the longevity makes the cost-per-year calculation genuinely favourable. A gold crown that lasts 25 years costs less per year than a porcelain crown that lasts 12.

What Determines Which Dental Crown Material Is Best

The conversation in the dental chair starts with position. Front teeth need the best aesthetics. Back teeth need the best strength. Premolars sit in the middle and can go either way. That narrows the field immediately, but it's rarely the whole story.

Bite forces are the next consideration, and they vary enormously between individuals. Someone who grinds their teeth at night puts extraordinary stress on crowns, and zirconia or metal handles that load far better than all-ceramic. How much tooth structure remains matters too: teeth with minimal structure benefit from materials that can be made thin (gold) or that bond chemically to the tooth (all-ceramic), while teeth with good remaining structure accommodate any material.

There's a subtler factor that most patients don't think about: the opposing tooth. A crown that bites against a natural tooth ideally shouldn't be much harder than that tooth, because a harder crown gradually wears down the enamel it meets. Gold matches enamel's wear rate perfectly. Zirconia and porcelain are harder and can cause accelerated wear on opposing natural teeth, though modern formulations have reduced this issue significantly. And occasionally, allergies guide the choice: nickel sensitivity (the most common metal allergy) rules out PFM crowns with nickel-containing alloys, while all-ceramic and zirconia are completely metal-free.

The Dental Crown Procedure

Regardless of material, the crown procedure follows the same sequence.

The tooth is prepared by reshaping it under local anaesthetic: removing a layer of enamel and dentin to create space for the crown. The amount removed depends on the material (0.5-1.5mm for all-ceramic, less for gold). An impression or digital scan captures the prepared tooth, and a temporary crown is placed while the permanent one is made in a laboratory over 1-2 weeks.

At the second appointment, the temporary crown comes off, the permanent crown is tried in, adjusted for fit and bite, and cemented in place. The whole process, from preparation to final cementation, takes two visits about two weeks apart.

At UrgentCare Dental, the crown consultation covers the assessment, material recommendation, and cost. The £650 fee includes the full procedure: preparation, impression, temporary crown, and the permanent crown in the recommended material.

Every crown material in 2026 is a genuinely good choice. The best choice is the one matched to the specific tooth, the specific mouth, and the specific patient. That's the conversation that happens in the chair, with the X-ray on the screen and the options laid out clearly. And that's a pretty great position to be in: four excellent materials, each with its own personality, each with situations where it's the obvious pick.
