Restore Your Smile with Dental Crowns in Markham

What is a dental crown?

A dental crown is a restoration that covers the tooth. It is a ‘dental cap’ that mimics the shape, form, strength, and other properties of the natural crown of the tooth (the part of the tooth clinically visible in the mouth). Your dentist may cement a dental crown to your tooth or a dental implant.

When is a dental crown indicated?

You may need a dental crown in either of these conditions:

To support the dental filling

If the tooth cavity is large, restoring a tooth with a simple amalgam and composite (white) filling may not be enough.  When a filling is large, the tooth becomes weaker may not be able to bear the occlusal forces during chewing. A dental crown can be placed on top of a dental filling to reinforce the strength and restore the functions of the tooth.

Post-root canal treatment (post-RCT)

A tooth that has had root canal treatment because of a large cavity or a deep crack or chip will often have a large filing.  Furthermore, a tooth will become weaker after RCT because the blood vessels and nerves are removed and the tooth no longer receives nutrients. A dental crown is placed in this situation to strengthen the RCT-treated tooth and reduces the risk of tooth fracture. A dental crown completely covers the tooth above the gumline and may extend below the gumline. If there is a leakage into the tooth due to a broken filling or tooth, it may lead to failure of root canal treatment. By encapsulating the tooth, a dental crown prevents the microleakage of microorganisms in the root canal.

With dental implants

A dental implant replaces the natural roots of the tooth. The dental implant anchors and provides support to the dental crown, dental bridge or a denture.

Discolored teeth

There are various options for teeth whitening. We offer the ‘in-office’ as well as the ‘at-home’ method of tooth bleaching. However, intrinsic stains like severe dental fluorosis or tetracycline staining, the stains are deeply ingrained. Such stains that occur in the deeper layers of the tooth cannot be effectively treated with professional teeth whitening. But don’t worry! We offer a broad range of cosmetic solutions and dental crown is one of them. All-ceramic and porcelain-fused-to-metal crowns can be used for cosmetic corrections.

Dental trauma

A large portion of tooth structure can be lost after a traumatic event. A dental crown restores the lost structure of the tooth. So, if your tooth is chipped off or a part of your tooth is broken, we can always fix it with a dental crown.

Abnormalities in the shape of the teeth

Many dental diseases affect the shape and form of the teeth. A dental crown can mask the dental defect and give you a picture-perfect smile.

What are the types of dental crowns?

The different types of dental crowns include:

  • Metal crown – This type of dental crown has metallic luster and is mostly used for restoration of your back teeth, which are not usually visible in smiling. It has high strength and durability.
  • Porcelain-fused-to-metal (PFM) crown – Choose this type of dental crown if you want a natural looking set of teeth. Porcelain helps to give your PFM crown a natural tooth color while still retaining maximum strength from the metal back-up
  • All-ceramic crown – It is a tooth-colored crown that gives excellent aesthetic results. These types of dental crowns are a good choice if you need a restoration of your front teeth or in the clinical situations where high aesthetics is important.

A dental crown can be a temporary crown or a permanent one. The above-mentioned types are the examples of a permanent crown. A temporary crown is placed after a tooth has been prepared to protect it while waiting for the permanent crown to be made.  It is removed after the permanent crown is ready.

What are the steps involved in the fabrication of dental crown?

A permanent dental crown is fabricated in a dental laboratory. At our clinic, it usually takes two appointments to prepare and insert a dental crown. Your dentist will first shape your tooth according to the choice of material. Then, the dental team will take an impression of your teeth so that we can make a replica of your oral cavity. This model is sent to the dental laboratory where the dental crown is made. At the next appointment, we will try the fit of the permanent dental crown, make the adjustments, polish it, and finally cement the dental crown on the tooth or dental implant.
