Types Of Crowns – The Quick Answer
The main types of dental crowns include porcelain, zirconia, E-max, porcelain-fused-to-metal (PFM) and gold crowns. Porcelain and E-max crowns are known to offer very good aesthetics – this makes both the crowns making ideal for front teeth where a natural look is really important. Zirconia crowns provide exceptional strength for back teeth, while PFM crowns combine a metal base with a tooth-coloured exterior for a balance of durability and aesthetics. Gold crowns are highly durable and particularly suitable for back molars that withstand heavy chewing forces.
💡 Whites Dental offers expert guidance and advanced tooth dental crown options in Central London.
Types Of Dental Crowns: A Comparison
Comparison Table
| Type Of Crown | Strength | Aesthetic | Best For |
|---|---|---|---|
| Porcelain Crowns | Good strength, but can chip or fracture under heavy biting forces. | Excellent, with a natural tooth-like colour and translucency. | Front teeth where a natural appearance is a priority. |
| Zirconia Crowns | Very high strength and excellent resistance to wear and fracture. | Good to excellent, depending on the zirconia material and translucency. | Back teeth and patients who need a strong, durable crown; suitable for front teeth with more translucent varieties. |
| E-max Crowns | Good strength, although generally less resistant to heavy biting forces than high-strength zirconia. | Excellent translucency and natural looking shade & colour. Strongly resembles natural enamel. | Front teeth and premolars where aesthetics are particularly important. |
| Porcelain-Fused-To-Metal (PFM) Crowns | High strength due to the metal substructure, although the porcelain layer can chip. | Good aesthetics. However, also associated with dark metal margin that can become visible near to the gum line. | Front or back teeth where a combination of strength and a tooth-coloured appearance is required. |
| Gold Crowns | Excellent durability, with high resistance to fracture and relatively little wear to opposing teeth. | Low aesthetic appeal due to the metallic colour. | Back molars where strength, longevity and resistance to heavy chewing forces are priorities. |
Porcelain Crowns
Porcelain crowns are among the most natural-looking dental restorations available. They are made entirely from ceramic material, offering excellent translucency and light reflection similar to real enamel.
Benefits Of Porcelain Crowns
- Highly aesthetic with superior colour matching
- Excellent translucency for natural light reflection
- Metal-free and fully biocompatible
- Resistant to staining
- Suitable for front teeth where appearance matters most
- Can be layered for highly customised natural shading
Limitations
- Less strong than zirconia under heavy bite force
- Not ideal for patients who grind or clench unless reinforced
- Can chip if excessive force is applied
- Requires removal of some enamel to ensure proper thickness
Best Uses
- Front teeth restorations
- Cases requiring high cosmetic quality
- Patients avoiding metal in dental work
💡 Porcelain crowns remain a leading choice when natural beauty is the priority.
Zirconia Crowns
Zirconia is a very strong compound used as a dental material for restorations. Made from zirconium dioxide, these crowns combine durability with improved aesthetics over older metal-based crowns.
Benefits Of Zirconia Crowns
- Exceptional strength — ideal for molars
- Highly resistant to fracture
- Withstands heavy biting forces
- Suitable for patients with bruxism
- Can be made in monolithic (one-piece) or layered forms
- Tooth-coloured alternative to metal
- Highly biocompatible
Limitations
- Less translucent than porcelain or E-max
- Can sometimes appear slightly opaque
- Requires precise prepping and polishing to avoid wear on opposing teeth
Types Of Zirconia Crowns
- Monolithic zirconia
Best for back teeth requiring maximum strength. - Layered zirconia
Combines strength with added aesthetic layering for front teeth. - High-translucency zirconia
A newer formulation offering improved cosmetic results.
Best Uses
- Molars and premolars
- Patients with strong bite force
- Situations requiring high durability
💡 Zirconia crowns are one of the best choices for long-term strength and stability.
E-max Crowns (Lithium Disilicate)
E-max is a brand of lithium disilicate ceramic known for its balance of beauty and strength. It is one of the most advanced ceramic materials used in dentistry.
Benefits Of E-max Crowns
- Excellent translucency and realism.
- Very strong for front and premolar teeth
- Metal-free
- Ideal for cosmetic smile restorations
- Minimally invasive tooth preparation
- Can be milled digitally for precision
Limitations
- Not as strong as full zirconia for molars
- Higher cost due to advanced ceramic technology
- May chip under extreme forces
Best Uses
- Front teeth
- Premolars
- Cosmetic smile makeovers.
- Cases requiring lifelike translucency
💡 E-max is often the preferred material for patients prioritising top-tier aesthetics combined with reliable strength.
Porcelain-Fused-To-Metal (PFM) Crowns
PFM crowns have a porcelain outer layer and an inner metal layer – fused together. This design provides strength with improved aesthetics over full metal crowns.
Benefits Of PFM Crowns
- Strong metal base for durability
- Porcelain overlay offers improved cosmetics
- Long-established and widely used
- Suitable for both front and back teeth.
Limitations
- Metal in the crown can sometime cause a dark line to appear at the gum line with time
- Porcelain may chip, exposing the metal underneath
- Less natural translucency compared to ceramics
- Not ideal for patients with thin gums
Best Uses
- Mixed-aesthetic cases
- Bridgework requiring strong underlying frameworks
- Back teeth where porcelain-only may risk fracture
💡 Though slowly being replaced by zirconia and E-max, PFM crowns still hold practical value in certain clinical situations.
Gold Crowns And Metal Alloy Crowns
Metal crowns made from gold, palladium, nickel or chromium alloys were once the standard for strength and longevity.
Benefits Of Metal Crowns
- Extremely durable
- Minimal tooth preparation required
- Longest lifespan of any crown type.
- Rarely fracture or chip
- Ideal for patients who grind or clench heavily
Limitations
- Poor aesthetics — visibly metallic
- Not suitable for visible teeth
- Allergies may occur with some base metal alloys
Best Uses
- Back molars
- Patients with very strong bites
- Occlusion-heavy cases requiring durability
💡 Gold crowns continue to be the most reliable long-lasting option, though aesthetics limit widespread use.
Composite Resin Crowns
Composite crowns are made from the same material as white fillings and are used less commonly today.
Benefits Of Composite Crowns
- Low cost
- Good temporary solution
- Easily repaired or adjusted
Limitations
- Weak compared to ceramic or metal
- Prone to staining
- Shorter lifespan
- Not ideal for heavy bite forces
Best Uses
- Temporary crowns
- Low-cost short-term restorations
💡 Composite is typically used as a provisional solution rather than a permanent restoration.
Stainless Steel Crowns (Mainly For Children)
These are pre-formed crowns often used in paediatric dentistry.
Benefits
- Durable
- Cost-effective
- Quick placement
- Effective for decayed baby molars
Limitations
- Metallic appearance
- Not suitable for adult teeth
Best Uses
- Children’s back teeth with extensive decay
💡 These crowns are functional but not aesthetic, and therefore not used for adult permanent restorations.
