Dental crowns have been around for a long time, and are still used to restore smiles today. Would you believe that ancient dentists used ivory, bone, and seashells to make crowns for teeth? They did – but at Cornwall Dental Arts in Cornwall ON, our materials are much more modern.
Evidence of gold crowns dates from 200 A.D. Porcelain crowns appeared in the 1800s. With the advancement of metal casting methods in the 1900s, crown technology took a big leap forward.
A dental crown procedure consists of numerous steps:
We anesthetize the tooth to be crowned and then prepare it. All decay is removed and the tooth is shaped.
Creating a Good Impression
We use a putty-like substance to create an impression of the tooth and surrounding teeth. An impression will also be made of the teeth that oppose the crown. This ensures that the crown does not negatively impact the bite.
The Temporary Crown
A temporary crown is used to safeguard the tooth and be sure it doesn’t move in the mouth while the permanent crown is being created. Patients need to be careful with their temporary crown. It is not as strong as the permanent crown and is attached only with temporary cement. Avoid chewing gum and eating sticky foods.
Choosing a Color
If the new crown will be created with porcelain, a shade guide helps you select a shade for the restoration.
The Lab Team Works Its Magic
A laboratory technician uses the model to build the crown. Same day restorations are created with a machine that mills a crown from a small block of ceramic in the correct shade.
Your Crown Is Put In Place
When the new crown is ready, it is placed in your mouth and the fit is dialed in.
