Variations And Applications Of Dental Crowns

Dental crowns are widely used in dentistry. The devices are designed to surround and cover the natural crowns of teeth. A natural crown is the portion of a tooth that you see when you smile or open your mouth; it is the tooth area that is not covered by your gums. 

When it comes to dental crowns, there are many different variations and applications. Here are a few questions and answers about crowns to help you better understand them.

Are some dental crowns stronger than others?

Although all dental crowns add support and strength, some crown materials are stronger than others. Crowns that are made of metal tend to be stronger than crowns that are constructed from porcelain or resin.

What materials are used to create tooth-colored crowns?

Tooth-colored crowns can be made from a variety of materials, such as the following:

  • Porcelain
  • Zirconium
  • Porcelain-over-metal
  • Resin

Are metal crowns still used for adult teeth?

In the past, adults frequently received metal crowns, even when front teeth were being restored. However, nowadays, many adults prefer tooth-colored crowns for teeth that are near the front of the mouth.

Stainless steel crowns are commonly used for back teeth. Not only are stainless crowns less expensive, but they can easily withstand large amounts of bite pressure as the molars grind food. Since the back teeth are not easily seen, the application of metal crowns to the molars rarely affects the appearance of a person's smile.

Are crowns used in children's dentistry?

Crowns are often used in pediatric dentistry to cover a tooth that contains a deep cavity. Although a tooth-colored crown may be preferred for an adult tooth or a primary tooth in the front of the mouth, stainless steel crowns are usually advised for baby teeth located on the sides or in the back of the mouth.

Unlike porcelain crowns that may require laboratory preparation, a stainless crown can be molded to a tooth. Thus, it can be applied during a single dental visit.

What are some of the ways in which dental crowns are used?

Dental crowns are used during root canal therapy, dental implant restorations and the repair of severely decayed teeth. Crowns also help secure dental bridges in the mouth.

Do dental crowns last a long time?

Dental crowns are long-lasting. However, some crown materials are more durable than others. Resin crowns tend to wear down faster than porcelain or metal crowns.
