Zirconia Crowns vs Porcelain Crowns:
Which Is Right for You?
Compare the strength, aesthetics, longevity and cost of zirconia and porcelain crowns at Dental Clinic London, South Kensington.
When you need a dental crown, choosing the right material is an important decision. Zirconia and porcelain (E.max) are the two most popular options in modern restorative dentistry — both are 100% metal-free, biocompatible and long-lasting, but they differ in strength, translucency and ideal placement. The best choice depends on which tooth needs the crown, your bite, and your aesthetic priorities. A clinical assessment is essential to determine the right material for your situation.
Zirconia vs Porcelain Crowns at a Glance
| Feature | Zirconia | Porcelain (E.max) |
|---|---|---|
| Material | Zirconium dioxide — milled from a single block (CAD/CAM) | Lithium disilicate (E.max) — pressed or milled glass-ceramic |
| Procedure Type | Restorative & cosmetic — 2 appointments | Restorative & cosmetic — 2 appointments |
| Treatment Time | 2 visits, 1–2 weeks apart (45–60 min each) | 2 visits, 1–2 weeks apart (45–60 min each) |
| Strength | Highest — extremely fracture-resistant under normal forces | High — strong enough for most teeth except heavy grinders |
| Aesthetics | Very good — modern multilayer zirconia has improved significantly | Excellent — best translucency, closest to natural enamel |
| Cost | From £995 | From £995 (E.max) or £1,195 (layered PFZ) |
| Longevity | 15–25+ years | 10–20 years (E.max) or 15–25 years (PFZ) |
| Suitability | Back teeth, bridges, implants, bruxism patients | Front teeth, smile zone, cosmetic cases |
What Are Zirconia Crowns?
Zirconia crowns are milled from a single block of zirconium dioxide using CAD/CAM technology. They are the strongest crown material available — extremely fracture-resistant under normal biting forces. At Dental Clinic London, zirconia crowns start from £995 and are 100% metal-free. They are the preferred material for bridges and dental implant restorations. Modern multilayer zirconia achieves very good aesthetics while maintaining exceptional durability.
2 appointments, each 45–60 minutes, spaced 1–2 weeks apart. A temporary crown protects your tooth while the permanent one is precision-milled.
15–25+ years with good oral hygiene and regular check-ups. Zirconia is the most durable crown material, with excellent resistance to fracture and wear.
Zirconia crowns are ideal if:
- You need a crown on a back tooth (premolar or molar)
- You grind or clench your teeth (bruxism)
- You need a dental bridge requiring maximum strength
- You need a crown on a dental implant
What Are Porcelain Crowns?
Porcelain crowns — specifically lithium disilicate (E.max) — are pressed or milled glass-ceramic restorations with the most natural translucency of any crown material. They closely replicate how natural enamel transmits and reflects light, making them the gold standard for front teeth, veneer combinations and cosmetic cases. E.max crowns start from £995. For cases requiring both aesthetics and added strength, layered porcelain-fused-to-zirconia (PFZ) crowns are available from £1,195.
2 appointments, each 45–60 minutes, spaced 1–2 weeks apart. Temporary crown provided. PFZ crowns may take slightly longer due to hand-layering by a specialist ceramist.
E.max crowns last 10–20 years. Layered PFZ crowns last 15–25 years thanks to their zirconia core. Both require good oral hygiene and a night guard if you grind.
Porcelain crowns are ideal if:
- You need a crown on a front tooth where aesthetics are paramount
- You want the most natural-looking result in the smile zone
- You are having a smile makeover with veneers and crowns
- You need a premium restoration that combines strength and beauty (PFZ)
Key Differences Explained
Strength & Durability
Zirconia is the strongest crown material — milled from a single block, it is extremely fracture-resistant. E.max is strong enough for most teeth but not recommended for heavy grinders on molars. For back teeth under heavy load, zirconia is the clear choice.
Aesthetics & Translucency
E.max porcelain has superior translucency — it replicates how natural enamel transmits light, making it virtually indistinguishable from natural teeth. Modern multilayer zirconia has improved aesthetics, but E.max remains widely regarded as the preferred material for the most visible teeth.
Tooth Preparation
Both materials require 1.5–2 mm of tooth reduction all around. The preparation process is identical — the difference is in the material the lab uses to fabricate the crown, not in how the tooth is prepared.
Longevity
Zirconia crowns last 15–25+ years. E.max crowns last 10–20 years. PFZ crowns (zirconia core + porcelain veneer) last 15–25 years. All are long-lasting — the difference is most significant for patients with heavy bites or grinding habits.
Cost
Both zirconia and E.max crowns start from £995 at our clinic. Layered PFZ crowns — combining a zirconia core with hand-layered porcelain — start from £1,195 due to the additional ceramist work required.
Tooth Position
Zirconia is preferred for premolars, molars, bridges and implant crowns where strength matters most. E.max is preferred for incisors and canines where aesthetics are paramount. PFZ offers the best of both for front teeth needing extra strength.
Pros & Cons
Zirconia Crowns
Advantages
- Strongest crown material available — extremely fracture-resistant
- 15–25+ years lifespan with proper care
- 100% metal-free and highly biocompatible
- Excellent for back teeth, bridges and implant crowns
- Ideal for patients who grind or clench (bruxism)
- Stain-resistant and highly durable surface
- Modern multilayer zirconia achieves very good aesthetics
Limitations
- Slightly less translucent than lithium disilicate (E.max)
- Traditional monolithic zirconia can appear more opaque
- Cannot be easily adjusted or repaired chair-side
- Aesthetics may not match E.max for the most visible front teeth
Porcelain Crowns (E.max / PFZ)
Advantages
- Best translucency — closest to natural tooth enamel
- Individually shade-matched for seamless colour blending
- Widely regarded as the preferred material for front teeth and the smile zone
- Smooth surface resists plaque accumulation
- Metal-free and biocompatible
- Layered PFZ combines zirconia strength with hand-crafted porcelain beauty
Limitations
- Not recommended for heavy grinders on back teeth
- Slightly less fracture-resistant than monolithic zirconia
- E.max may not be suitable for long-span bridges
- PFZ porcelain layer can chip under extreme force
- PFZ option carries a higher cost (from £1,195) due to ceramist hand-layering

Which Option Is Best for You?
Best for Back Teeth Durability
→ Zirconia
For premolars and molars that endure heavy chewing forces, zirconia is the strongest option. Its fracture resistance makes it the preferred material for back teeth, especially in patients who grind or clench.
Best for Natural Front Tooth Aesthetics
→ E.max Porcelain
For incisors and canines in the smile zone, E.max porcelain offers the most natural translucency — virtually indistinguishable from your natural teeth. It is widely regarded as the preferred material for cosmetic crown cases.
Best for Long-Term Strength
→ Zirconia
If maximum longevity is your priority, zirconia crowns at 15–25+ years offer the longest expected lifespan. They are also the material of choice for bridges and implant-supported crowns.
Best for Balanced Aesthetics & Strength
→ Layered PFZ
Layered porcelain-fused-to-zirconia crowns combine the strength of a zirconia core with hand-layered porcelain for lifelike aesthetics. The premium choice for front teeth that need both beauty and durability.
Many patients combine both materials — zirconia on back teeth and porcelain on front teeth. Explore our smile makeover options or contact our team for personalised advice.
Recovery & Aftercare
Aftercare is the same for both zirconia and porcelain crowns. With good habits, either material will provide many years of reliable service.
Daily Care
- Brush twice daily — focus on the crown-tooth margin
- Floss daily including either side of the crowned tooth
- Avoid biting very hard objects (ice, pen caps, hard sweets)
- Wear a custom night guard if you grind or clench
Professional Monitoring
- Attend check-ups every 6 months for crown assessment
- Regular hygiene appointments to maintain gum health around the crown
- Report any changes — looseness, bite discomfort or sensitivity
- If you have a root canal treated tooth, regular monitoring is especially important
