Zirconia crowns
Metal-free crowns that let light through much like a natural tooth. For teeth with major structure loss, root canal treatment or heavy discoloration, at the front or back of the mouth.

What is a zirconia crown?
A zirconia crown covers the whole tooth, with a framework made of a strong ceramic called zirconia instead of metal. The grey shadow that can appear at the gum line with metal-ceramic crowns does not occur with zirconia, and because it lets light through more like a natural tooth, it gives an aesthetic result, especially on front teeth.
When is it used?
- Teeth with large fillings or fractures and significant loss of structure,
- Teeth weakened over time after root canal treatment,
- Heavily discolored teeth that do not respond to whitening,
- Bridges replacing missing teeth,
- Restorations on implants,
- Replacing old metal-ceramic crowns.
For healthy front teeth where only a change in color or shape is wanted, veneer options that need less preparation are considered first.

Treatment steps
- Examination and X-ray. The root and surrounding area are assessed; root canal or gum treatment is done first if needed.
- Preparing the tooth. Under local anesthesia, the tooth is reduced to make room for the crown.
- Impressions and temporary crown. Impressions go to the laboratory and a temporary crown is fitted in the meantime.
- Trial. Fit, color and bite are checked.
- Cementing and follow-up. With your approval, the crowns are cemented permanently.
Care
The tooth under a zirconia crown can still decay and the gum around it can become inflamed. Brushing twice a day, using floss or interdental brushes and a check-up every six months are important. Special cleaning aids are recommended for cleaning under bridges.
Frequently asked questions
How long do zirconia crowns take?
Usually a few appointments. The timeline depends on any treatment needed beforehand and on the laboratory stage.
What is the difference between zirconia and metal-ceramic crowns?
Zirconia has no metal in its framework; it lets light through more naturally and does not create a grey shadow at the gum line. Which one is suitable depends on the position and condition of the tooth.
Are teeth reduced for zirconia crowns?
Yes, some tooth structure is removed around the tooth to make room for the crown. This is done under local anesthesia.
Can zirconia be used on back teeth?
Yes. Zirconia is a strong material and, with proper planning, can be used on back teeth too.
Veneers or zirconia?
A veneer covers only the front surface and removes less tooth structure; zirconia covers the whole tooth and is preferred for teeth with large fillings, fractures or root canal treatment. Which one is suitable is decided at the examination.
