A crown, often called a cap, is an artificial covering for the visible part of your tooth. Crowns are generally made of porcelain avoiding the need for metal alloys. You may need a crown if you have had root canal treatment, have large fillings in a tooth, a broken tooth, or severely stained, misshapen, or misaligned teeth. A crown covers part or all of the visible portion of your tooth and protects it from further damage. They are strong, long-lasting and absolutely stunning in their recreation of natural teeth. And the colour is so natural, you’ll have a very difficult time telling these from your original teeth.
