E.max and zirconia are the two most common materials for modern tooth-coloured crowns. In short, E.max is usually chosen where appearance matters most, such as front teeth. Zirconia is usually chosen where strength matters most, such as back teeth or people who grind. Many patients could have either, and your dentist will recommend one based on the tooth and your bite.
What Is an E.max Crown?
E.max is a lithium disilicate glass-ceramic. It has a natural translucency similar to enamel, so it blends well with neighbouring teeth. E.max crowns can be milled using CAD/CAM technology and then stained and glazed, or layered by a ceramist for more detailed colour.
The same material is also used for E.max veneers.
What Is a Zirconia Crown?
Zirconia is a very strong ceramic. Solid (“monolithic”) zirconia crowns are highly resistant to breaking, which makes them well suited to molars and to people who clench or grind. Older zirconia looked more opaque, but newer translucent types look more natural, especially when layered with porcelain.
E.max vs Zirconia at a Glance
| E.max (lithium disilicate) | Zirconia | |
|---|---|---|
| Appearance | Very natural; translucent | Good; more opaque, improved in newer types |
| Strength | Strong | Very strong |
| Best suited to | Front teeth, premolars, visible areas | Molars, heavy bites, grinding, some bridges |
| Tooth preparation | Needs enough thickness for strength | Monolithic types can often be made thinner |
| Single-visit option | Often, when milled with CAD/CAM | Usually laboratory-made |
| Bonding | Bonds strongly to enamel | Usually cemented; bonding is more limited |
Front Teeth: Why E.max Is Often Preferred
On front teeth, a crown needs to match the colour, translucency and surface texture of the teeth beside it. E.max handles this well, particularly when a ceramist adds custom staining or layering. It can also be matched alongside porcelain veneers, so a crown and veneers look like a set. Read veneers vs crowns.
Back Teeth and Grinders: Why Zirconia Is Often Preferred
Molars take the most chewing force. If you grind or clench, or the tooth has very little height left, zirconia’s extra strength can lower the risk of a crown fracturing. Appearance matters less at the back of the mouth, so zirconia’s slightly more opaque look is rarely an issue.
Whichever material is used, a night guard is often recommended if you grind.
How Long Do They Last?
Both E.max and zirconia crowns can last many years with good care, although lifespan varies. Decay at the edge of the crown, gum disease, grinding and biting hard objects are the most common reasons crowns need replacing. Regular check-ups and cleaning between the teeth help.
What Do Crowns Cost at Our Practice?
At Sydney Dental Veneers, a CAD/CAM ceramic crown is $1,820 per tooth and comes with a 5-year limited warranty; conditions apply, including regular check-ups and cleans. Custom layering or staining adds $100. Root canal treatment or a core build-up, if needed, is quoted separately. Laboratory-made crowns, including zirconia where recommended, are quoted after an examination.
Crowns are often covered in part by health funds as major dental, depending on your policy. We offer HICAPS claiming for eligible items. Interest-free payment plans are available, subject to approval. See dental crown cost in Sydney and the dental crowns package.
Which Should You Choose?
The right material depends on the tooth’s position, how much tooth remains, your bite and how important an exact colour match is. Your dentist will explain the options and why one is recommended for each tooth. Learn more about dental crowns, or book a consultation at Suite 302, Level 3, 70 Pitt Street, Sydney CBD.

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
Frequently Asked Questions
Which is stronger, E.max or zirconia?
Zirconia is stronger. E.max is still strong enough for most front teeth and premolars, and is chosen for its more natural appearance.
Which looks more natural, E.max or zirconia?
E.max is generally more translucent and natural-looking, which is why it is often used for front teeth. Newer zirconia types look better than older ones.
Is an E.max crown good for a molar?
Sometimes, but for molars, heavy bites or grinding, zirconia is often recommended because of its extra strength.
How much is an E.max crown in Sydney?
At our practice, a CAD/CAM ceramic crown is $1,820 per tooth, with custom layering or staining $100 extra.
Can I get a crown in one visit?
Milled CAD/CAM ceramic crowns can often be made and fitted in a single visit. Your dentist will confirm whether this suits your tooth.
