posted in: General Dentistry | 0

Dental crowns are among the common dental treatments that dentists perform. No matter how common this treatment is, some people are frightened and scared of undergoing this procedure due to the inaccurate information they heard somewhere else.

In fact, dental crowns are nothing to be frightened or scared of. Dental crown does not only provide an aesthetically beautiful result, but they are also essential in keeping the mouth healthy and improving the functions of the tooth. 

What are dental crowns?

Dental crowns are tooth-shaped caps that are placed over the tooth that has been severely damaged or decayed. They are fixed prosthetic devices that are cemented onto the damaged tooth, fully encasing the entire visible portion of the tooth that lies at and above the gum line.

Dental crowns are needed to:

  • Restore a broken tooth or a tooth that has been severely worn down
  • Protect a weak tooth from breaking or hold the parts together of a cracked tooth
  • Hold a dental bridge in place
  • Cover dental implant
  • Cover and support a tooth with a large filling when there is not enough tooth left
  • Make a cosmetic modification
  • Cover misshapen or severe discoloration of the teeth

The process of placing a dental crown

Placing the dental crowns are usually done in two visits. The first step usually involves examining and preparing the tooth for a crown. The second visit consists of the placement of the permanent crown.

During the first visit, the dentist may take a few x-rays of the mouth to examine the condition of the tooth’s root and its surrounding bone. If the tooth has extensive decay or if there is a risk of infection or injury in the pulp, then a root canal treatment must be performed first.

Before the placement of the crown, the affected tooth needs to be filed down along the chewing surfaces and sides to make room for the crown. The amount of the tooth structure that needs to be removed will depend on the type of crown used. A foundation is required if large portions of the tooth structure are severely damaged, decayed, or missing. 

After the tooth has been restored, the dentist will make an impression of the tooth receiving the crown. Sometimes, impressions are made with a digital scanner. Then, the impression or scans are sent to a dental laboratory to manufacture the crown. If the crown is made of porcelain, the dentist will select a shade that closely matches the color of the adjacent teeth. A temporary crown is then placed to cover and protect the prepared tooth until the permanent crown is ready. 

During the second visit, the temporary crown is removed and be replaced by a permanent crown to check its fit and color. If there are no more adjustments to be made, the tooth is then numbed with a local anesthetic to place the new crown permanently.

How long do dental crowns last?

Dental crowns can last for five years or more, depending on how it is taken care of. They must follow proper oral hygiene diligently and regularly going to their scheduled dental appointment.
