Dental Crowns

What Are Dental Crowns?

Basically, a dental crown is a “cap” that is positioned over a tooth with the intention of restoring the tooth’s shape, strength, size as well as enhancing the tooth’s appearance. The crown is positioned in a way that it completely encases the visible part of a tooth lying at and above the patient’s gum line.

Why Dental Crowns?

Apart from offering protection to weak teeth and keeping the affected teeth from breaking, dental crowns serve a number of purposes. If you have a cracked tooth or your tooth has seriously worn down, your dentist may use dental crowns to hold together parts of the affected tooth or teeth. Similarly, dental crowns are extremely effective in restoring a tooth or a set of teeth that are broken or have been affected in some other way.

As part of the treatment strategy, a dentist may use a crown for holding a patient’s dental bridge in place. Whether it’s covering a misshaped tooth or improving the look of discolored teeth, dental crowns are the ideal choice for a variety of dental procedures. Moreover, these crowns are even used for covering a dental implant or a tooth that has gone through a root canal.

What’s The Procedure?

It’s basically a two-visit process. When patients make their first visit, dentists work to shape the tooth and take the impression. Later, a temporary crown is placed. The patient is asked to make a second visit while a dental technician fabricates the crown. During the second visit, the finished crown is cemented in place.

Which Type of Dental Crown Would Your Dentist Choose?

There is a whole variety of permanent dental crowns that are available out there for your dentist to choose from. There are crowns that are made of metal, then there those all resin, or all ceramic varieties.

Some dentists choose to go for metallic crowns that are essentially composed of gold alloy or other alloys. Since these crowns are known for their benefit of withstanding biting as well as chewing forces, they are more durable and tend to last longer. In some cases, dentists may consider using porcelain-fused-to-metal dental crowns that can be color matched to the adjacent teeth. A dentist may prefer these crowns over metallic ones because of this specific feature. But then, these crowns aren’t as durable as the ones made from metal. As these crowns mostly have a normal teeth appearance, dentists consider using them for back or front teeth.

Another variety is the all-resin dental crowns that are regarded as a more affordable option. But, these crowns tend to wear down easily and are more likely to have fractures as compared to porcelain-fused-to-metal crowns. The fourth option is the all-ceramic or all-porcelain dental crowns that offer the most ideal color match as compared to other crowns. Dentists specifically consider these crowns for patients who have metal allergies. However, it’s important to note that these crowns aren’t as strong as porcelain-fused-to-metal crowns.
