Several Forms of Dental Crowns
Teeth cleanings, cavity fillings and bonding’s comprise most of a dentist’s routine sessions. But now more involved procedures are common and even easier to complete. In addition to root canals and wisdom tooth extractions, dental crowns are often needed as well and come in several forms. Before we differentiate between the different types of dental crowns, consider the functions they serve.
Dental crowns (or a cap) is a fixed prosthetic object that is cemented onto the tooth. Only your dentist can remove it after it’s been put in place. A crowns main purpose is to cover a damaged tooth, but also strengthen 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 soon enough. Before the impression is made, your dentist will first need to 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 created.
Now overall there are 4 types of dental crowns:
Ceramic — Used for restoring the front teeth and are popular in this area for their unique ability to blend with your natural tooth color. The crown is made out of a porcelain-based material.
Porcelain-fused to metal – Provides a stronger bond than regular porcelain because its foundation is a metal structure and is extremely durable.
Gold alloys – A crown with a mix of gold, copper and other metals. In addition to providing a stronger bond to the tooth, it doesn’t fracture, nor does it wear away the tooth itself overtime.
Base metal alloys – This particular crown is made up of non-noble metals that are highly resistant to corrosion and make for a very strong crown. It’s also the crown that requires the least amount of healthy tooth to be removed prior to fitting.
