While it doesn’t come with a throne or unlimited power, a dental crown remains a work of beauty for your smile.
We recommend crowns, a part of restorative dentistry, when patients have a tooth with an irregular size, shape or strength.
Millions of people across the United States and globally have a dental crown to replace a missing tooth or strengthen a weakened tooth. A dental crown is a applied over the tooth to provide it with protection and support. It completely encases the visible tooth surface, including the gum line, before becoming bonded in place.
But, much like crowns of old, not all crowns are made equal.
When we talk about different types of crowns, the conversation really centers on the different types of materials used to create a crown. Some materials look more natural, while others are more durable.
Types of Dental Crowns
In general, we turn to four main types of materials for this type of restorative work. Those include:
- Metal alloys, including mercury and gold
- Ceramic or porcelain-based
- Porcelain fused to metal
- Resin
Pros and Cons
Each material brings its own strengths and weaknesses to the table.
Let’s start with metal alloys.
Historically made from a combination of metals, amalgam crowns are the strongest type, lasting up to 20 years with proper dental hygiene. Recently, some have questions the use of mercury, although the American Dental Association deems the usage safe.
Very low levels of mercury are used, and the poison is negated when mixed with other materials, like zinc and copper. Some people discover they are allergic to mercury, making this a poor option.
Ceramic or porcelain-based crowns remain popular if the problem area is in the front teeth, as it closely mimics a natural tooth in coloring and in the way it reacts to lights. The downside? It’s just not as strong as metal, which can results in breakage or fracturing from wear and tear.
That brings us to the porcelain crowns joined to metal. Here we gain the advantages of both metal and ceramic, as we cover a metal crown with porcelain. It’s more natural looking and stronger, but the outer material still may break.
Resin crowns cost the least but are prone to splitting. Made from composite material like with a filling, this type works well with the front teeth thanks to its natural look. Another advantage is that it won’t wear down nearby teeth.
