Advantages & Disadvantages Of Zirconia Crowns

Zirconia crowns are made of zirconia or zirconium oxide, and are very tough and durable in nature. Since such crowns have several advantages over traditional metal and porcelain dental implants, many people these days prefer to opt for them. So, here’s a brief overview of the advantages and disadvantages of zirconia crowns:


    • Natural look: Zirconia crowns can be translucent enough to blend with other teeth and give a natural look. What’s more, if bonded to the teeth rather than being cemented with conventional dental cement, these crowns won’t display a black line at the gum line.
    • Strength: Where porcelain crowns are prone to chipping, zirconia crowns are almost indestructible. In fact, these crowns can be up to five times stronger as compared to their porcelain/metal counterparts.
    • Durability: Unlike crowns of other materials that may typically last for around 10 years or so, those made of zirconia are likely to last a lifetime.
    • Less sacrifice of healthy tooth: Since zirconia crowns can offer superior strength in less volume than crowns made of other materials, they can be made to fit even when not much space is available for porcelain build up.
    • Biocompatible: Zirconia is completely compatible to human body. Since it is inert, and the body does not reject zirconia, you need not worry about facing allergies or unfavorable reactions.
    • Corrosion resistant: Zirconia crowns are resistant to corrosion, which adds to their longevity factor.

  • Less labor-intensive: Since more of the present tooth is retained, nominal preparation is required for fitting these crowns as compared to metal or porcelain crowns.
  • Cost-effective: Zirconia crowns are considerably cheaper than porcelain crowns, and cost almost the same as gold-based metal-porcelain crowns. However, the long list of benefits that they bring to the table make them cost-effective than crowns made of other materials.


  • Abrasive effect: The toughness of zirconia crowns can have an abrasive quality, which causes friction against the root of the affected tooth as well as with other teeth.
  • Decay under the crown: Though these crowns are meant to last a lifetime, the decay underneath the crown my cause them to loosen and fall.

As with everything in life, advantages often come with a price. This holds true for zirconia crowns too. Still, when you weigh the long list of advantages against a minor setback or two, zirconia crowns surely emerge as the prudent choice.
