Answering Brief Questions About Dental Crowns

posted in: Crowns and Bridges | 0

When you have a weak tooth that needs to be held together or discolored tooth that you wish to conceal, the dentist may recommend you to get dental crowns.

Dental crowns are a fixed prosthetic device that is placed over a tooth. It is used to cover, restore the shape and size, strength, and improve the appearance of the tooth. When crowns are cemented into place, they cover the entire visible portion of a tooth that lies at and above the gum line.

Why are dental crowns necessary?

  • They protect a weak tooth from breaking
  • Cover a dental implant
  • Cover and support a tooth with a large filling when there isn’t a lot of tooth’s structure left
  • Hold the dental bridge in place
  • Make a cosmetic modification
  • Cover misshapen or severely discolored teeth
  • Restore an already broken tooth or severely worn-out tooth

What are the types of dental crowns?

Dental crowns can either be temporary or permanent. They can be made from various materials depending on the patient’s preference or needs.

Metals. Metal crowns usually include alloys that have high gold or platinum content or base-metal alloys like cobalt-chromium and nickel-chromium. Metal crowns can withstand biting and chewing forces well, can endure wear or tear, and rarely chips or breaks. The downside of a metallic crown is its metallic color—the reason why it is used for the molars near the back of the mouth.

Porcelain-fused to metal. This type of crown is suitable for the front or back teeth, or when a dental bridge needs support from the metal. The advantage of this is its appearance that matches the adjacent teeth. However, this type of crown can show more wear, can chip or break, and its underlying metals can show through as a dark line over time.

All resin. Dental crowns made from resin are not as expensive as other crowns, and they tend to wear down over some time. They are also susceptible to fracture compared to porcelain-fused metal crowns.

All-ceramic or all-porcelain. This type of crown is suitable for persons who have metal allergies. They provide a more natural-looking color match better than the rest of any other materials do.

Temporary. Temporary crowns can be made right in the dentist’s clinic to provide a temporary covering to the tooth while the permanent crowns are made in the dental laboratory. Usually, this type of crown is made from acrylic-based material or stainless steel.

How long do dental crowns last?

Usually, dental crowns last for around five years or more depending on how well a person follows good oral hygiene practices and how often they visit the dentist regularly. By observing proper care to one’s teeth, the lifespan of the dental crown can last for many years.

Does it require special care?

A crowned tooth does not necessarily require special care. However, getting dental crowns does not mean that the tooth is completely protected from decay or gum disease. Practicing proper oral hygiene and regular visits to the dentist are essential in keeping the mouth healthy. Proper oral hygiene includes brushing the teeth at least twice a day, especially on the crown area where the gum meets the tooth.
