Depending on the condition of your mouth at any one time, your dentist performs several different types of procedures. Although teeth cleanings, cavity fillings and bondings comprise some of the routine sessions, more involved procedures are now common and easy to complete. In addition to root canals and wisdom tooth extractions, dental crowns are often needed as well, and come in more than one form. Before differentiating between the different types of dental crowns, consider the functions they serve.
A dental crown (also referred to as a cap) is a fixed prosthetic object that is cemented onto a tooth. Only a dentist can remove it once it’s in place. The main purpose of a crown is to cover a damaged tooth, but it also strengthens it, improving its overall appearance and alignment in the mouth.
Crowns are made by taking an impression of the tooth or teeth they’ll be covering. Before this impression is created, your dentist must first reduce your tooth’s size so that the crown fits properly. Your dentist may also place a temporary crown while the permanent one is being made.
Types of Dental Crowns
There are four different types of dental crowns.
- Ceramic — These are used for restoring front teeth, and are popular in this area for their ability to blend with your natural tooth color. The crown is made of a porcelain-based material.
- Porcelain-fused to metal – This crown provides a stronger bond than regular porcelain because it is connected to a metal structure. It’s also extremely durable.
- Gold alloys – This crown is a mix of gold, copper and other metals. In addition to providing a strong bond to the tooth, it doesn’t fracture, nor does it wear away the tooth itself.
- Base metal alloys – This crown is made up of non-noble metals that are highly resistant to corrosion, and make for a very strong crown. It also requires the least amount of healthy tooth to be removed prior to fitting.
