Zirconia vs E-max Crowns: Strength, Appearance and Cost

Neither zirconia nor E-max crowns are right for every tooth; each suits a different set of priorities. Zirconia crowns are prized for their strength and are usually chosen for molars and premolars that take the heaviest chewing forces. E-max crowns are more translucent, which is why they are usually chosen for front teeth, where light passing through the crown gives a more natural look. Both are metal-free, all-ceramic materials, and both are covered by the same crown warranty at Er Dental Clinic. Your dentist confirms which material suits your bite, tooth position and budget after reviewing your X-rays.

A zirconia crown is a full-coverage dental crown milled from zirconium oxide, a strong ceramic material that contains no metal. Zirconia crowns can be made monolithic, from one solid block of zirconia, or layered with a porcelain surface for extra translucency, so the same core material covers a range of looks from very strong to more natural in appearance. Because zirconia resists chipping and cracking well, it is a common choice for back teeth that do heavy chewing, including molars that have already had a root canal. Zirconia crowns are also placed on front teeth when strength is the priority, for example for patients who grind their teeth heavily. Er Dental Clinic fits zirconia crowns as single crowns or as part of a full smile rehabilitation package; our zirconium crown page covers the material, fitting process and aftercare in more detail.

An E-max crown is milled from lithium disilicate, a glass ceramic made by Ivoclar that is known for how well it lets light pass through, giving a translucent, tooth-like appearance. Because of this translucency, E-max crowns are often chosen for front teeth, where matching the natural colour and light behaviour of the surrounding teeth matters most. E-max is also used on back teeth in some cases, although it is generally considered less resistant to chipping under a heavy bite than zirconia. E-max crowns are bonded to the prepared tooth in many cases, which can add to how well they hold once fitted. Our e-max crowns page sets out the fitting process, aftercare and who the material typically suits.

The core difference between zirconia and E-max comes down to a trade-off between strength and how light passes through the crown. Zirconia is the stronger of the two ceramics and resists chipping and cracking well, which is why it is generally recommended for molars and for patients who grind or clench their teeth heavily. E-max is more translucent, so light behaves more like it does in natural enamel, which is why it is generally recommended for front teeth where appearance is the priority. Neither material is simply better across the board: a zirconia crown on a front tooth can look slightly more opaque than a neighbouring natural tooth, while an E-max crown on a back molar may need closer monitoring for chipping in a heavy bite. Both are metal-free, all-ceramic options within our full ceramic crowns range, and both are quoted per unit rather than per arch.

The comparison below sets out the qualitative differences that come up most often in a consultation. It does not replace an individual assessment: your dentist confirms which criteria apply to your tooth after reviewing your X-rays.

The choice is made from your X-rays, your bite and the position of the tooth, not from a general rule of thumb. Your dentist, such as Vijdan Aslanoglu, looks at how much chewing force the tooth carries, whether you show signs of grinding or clenching, and how visible the tooth is when you smile. A back molar with a heavy bite generally points towards zirconia, while a front tooth where colour and light behaviour matter most generally points towards E-max. Where both strength and appearance matter, a layered zirconia crown with a porcelain surface is sometimes discussed as a middle option. The final recommendation, together with the price for your case, is set out in your written treatment plan before you travel.

If you are not yet sure a crown is even the right treatment, our dental crowns page introduces every type we offer, including zirconia, E-max, PFM and full ceramic options. If your tooth is broken, cracked or badly worn, our broken and worn teeth page explains the repair options a dentist typically considers, including when a crown is recommended over a filling or inlay. If you already know you need a crown but are still unsure which material fits your situation, our full guide on which dental crown is right for me walks through front teeth, back teeth, grinding and budget in more detail.

Zirconia crowns at Er Dental Clinic start from £215 / €250 / $290 per unit, and E-max crowns start from £300 / €350 / $400 per unit.
