A dental crown is a form of restorative dental treatment used to improve the function and appearance of a tooth that has sustained significant damage such as a break, crack, or large cavity that threatens the whole tooth.
Also known as a cap, the crown is a hollow covering that fits over the existing tooth to protect it from further damage and restore its appearance and function.
Types of crowns
Crowns are made from a variety of strong restorative materials. Your dentist will select the material used for your crown based on factors including the size and position of the tooth to be crowned and the bite force in the area.
Before embarking on this restorative procedure, your dentist will discuss the various options with you and explain their strengths and potential drawbacks.
All-metal
Also known as full gold crowns, these crowns are in fact composed of several different types of elements, including gold, silver, tin, and more. The advantages of gold crowns include strength and durability—they can last a long time and will not chip or break.
Porcelain fused to metal
These crowns are known for being both natural looking and stronger than porcelain or ceramic crowns.
All-porcelain
Porcelain crowns are the most natural looking option for your smile. However, they may chip more easily and for that reason are not usually placed on back teeth. CEREC and E-Max are examples of all-porcelain crowns.
Porcelain fused to ceramic
Procera crowns are an example of porcelain fused to ceramic crowns. These crowns provide a natural appearance and are free of metals or alloys.
Getting a crown
The process of getting a crown can be broken down into these general steps:
1
After the affected tooth is filed down to make room for the crown, an impression of the tooth and surrounding area is taken using a rubber-like material. This ensures that the crown will be the right fit, shape, and bite for your mouth.
2
Your dentist places a temporary plastic crown over the affected tooth to protect it until the final crown is ready.
3
Your crown is custom made in a laboratory using the impressions taken of the affected tooth and surrounding area.
4
At your next visit, the dentist removes the temporary crown and places the final crown. Any minor adjustments needed to ensure optimal fit, function, and appearance are made, and the crown is then cemented into place.
Preserving the life of your crown
Crowns are made from strong, durable materials and may last for several years with proper daily care. Brush and floss your crown as you do your natural teeth. Your dentist will tell you how long you can reasonably expect your crown to last, based on your specific clinical situation.
