Dental Crown

What is a crown?

Crowns are a type of protective restoration placed over the top of a tooth to restore a tooth’s strength or help improve its shape. In most cases, crowns are used when a tooth has been cracked, worn down or partly destroyed due to decay.

How does a crown work?

A crown covers a tooth that has been damaged. Not only will a crown strengthen a tooth, it will also improve its shape, alignment and appearance. Crowns are placed over teeth or implants to provide the correct shape for proper bite and function.  Ceramic or porcelain crowns can be matched to your natural tooth color.  Crowns can also be made of alloys like gold or other metal.  Each case is specific.  Porcelain is a popular choice since it is both attractive and strong.

When is a crown recommended?

There are several instances when a tooth may need a crown. These include:

  • To keep a weakened tooth from splitting or fracturing
  • To restore a broken tooth
  • To attach a bridge
  • To cover an implant
  • To cover a tooth that is discolored or poorly shaped
  • To cover a tooth that had a root canal and is at risk of fracture

What steps are taken to prepare a tooth for a crown?

Usually two visits are needed to prepare a tooth for a crown. The first visit is when the Markham dentist will examine your tooth and then do any needed preparations of the tooth. The second visit is for placing the crown and ensuring its proper function and esthetics.

How will the dentist prepare the tooth for a crown?

The tooth to be crowned is shaped in accordance to the type of crown material selected.  Once the tooth is ready, the dentist will make a mold of the tooth so that the crown can be made to fit perfectly. We will then place a temporary crown on the tooth to protect it while the permanent one is processed. During the second visit the dentist will place the permanent crown on the tooth.  We will check that the crown fits well and has the beautiful esthetics to match your smile.
