The crown is the part of the tooth that rises above the gums. It is also a type of dental restoration that caps or encircles a natural tooth or implant. Crowns improve aesthetic appeal, but they also help to reinforce the tooth.
When is a crown needed?
If the dental cavity is small, and if after having cleaned the cavity, the structure of the tooth can still withstand it, the dentist simply fills the cavity using an amalgam, resin or composite filling. However, should the tooth now be too thin, the dental structure too fragile or too weak, a crown will have to be placed.
A dental crown is also required in the following situations:
- When a tooth is seriously damaged;
- After a root canal;
- To cover a dental implant (see also implant supported crown).

How is a crown made?
Previously, crowns could only be milled in a dental laboratory. This required the use of a temporary crown and patients had to come to the clinic a second time to complete the installation.
Since 1997, we have been using the CEREC German technology. This allows us to mill your crown on site and complete the crown installation in a single visit. Here are the steps for the installation of a dental crown:
- The dentist prepares the tooth;
- A digital imprint is made of the tooth (no more uncomfortable paste in your mouth);
- The dentist finalizes the shape of the crown on his chair-side computer;
- The crown specifications are sent to the milling machine tool;
- The crown is milled in a few minutes and placed in the mouth;
- The occlusion is adjusted to perfection;
- You leave the clinic with a happy smile.
With CEREC, you save time and the quality of the crown is unrivalled.
