When is a zirconia crown the right choice?
A crown is considered when the tooth's own structure is not strong enough on its own, or when its appearance cannot be corrected with a filling or veneer.
- Teeth with large fillings or teeth that are broken
- Teeth weakened after root canal treatment
- Replacing old metal-ceramic crowns
- Severe discolouration that cannot be corrected with whitening or veneers
- Replacing missing teeth with a bridge
How does it differ from a metal-ceramic crown?
Zirconia crowns contain no metal. Because they let light through in a way closer to natural teeth, they look more lifelike, and they do not cause the grey shadow at the gum line that can be seen with metal-based crowns.
Zirconia is a material that is compatible with the body's tissues. At our practice we use high-quality, certified materials, and crowns are made with careful craftsmanship.
How much is the tooth reduced?
Because a crown covers every surface of the tooth, the tooth needs to be reduced in a controlled way on all sides; this preparation is greater than for a veneer. The procedure is carried out under local anaesthetic, and a temporary crown is fitted until the permanent crown is ready.
The temporary crown protects your tooth from sensitivity during this time and keeps your appearance intact. It is advisable to avoid very hard and sticky foods during this period.
Care for long-term use
The crown itself cannot decay, but decay can develop in the natural tooth at the edge of the crown. This is why regular brushing, using dental floss or interdental brushes, and check-ups are important.
If you clench or grind your teeth at night, a night guard may be recommended to protect both your crowns and your natural teeth. In everyday life you can eat and drink normally with your crowned teeth.
How does the treatment work?
- Examination and X-rayThe root of the tooth and the surrounding tissues are assessed; if needed, root canal treatment or a filling is done first.
- Preparation and impressionsThe tooth is prepared under local anaesthetic, impressions are taken and the shade is selected.
- Temporary crownYour tooth is protected with a temporary crown while the permanent crown is made in the laboratory.
- Try-in and cementationThe fit, colour and bite of the crown are checked and, with your approval, it is permanently cemented.
Frequently asked questions
How long does it take to make a zirconia crown?
In most cases it is completed in two to three sessions over about one to two weeks. If preliminary treatment such as a root canal is needed, it may take longer.
Is having a zirconia crown painful?
Because the preparation is carried out under local anaesthetic, you usually feel no pain during the procedure. There may be mild sensitivity for a few days afterwards, which in most cases passes on its own.
Zirconia crown or porcelain veneer?
If your tooth is largely sound, a veneer is often chosen; if there is significant loss of structure or the tooth has had root canal treatment, a zirconia crown is usually preferred. The decision is made after an examination, based on the condition of your tooth.
Can the tooth under a zirconia crown decay?
The crown itself does not decay, but the natural tooth at its edge can decay if it is not cared for properly. Regular cleaning and check-ups reduce this risk.
