Crowns

A dental crown is a custom-made tooth-shaped cap that is placed over a damaged or weakened tooth to restore its strength and appearance. It is tailored to match the shape, size, and colour of natural teeth, providing both aesthetic appeal and functional restoration.

Dental crowns can be crafted from various materials, such as porcelain, zirconia, ceramic, metal alloys, precious gold, or a combination of these, depending on specific needs and preferences.

The primary purpose of a dental crown is to protect, cover, and restore the shape of a damaged or decayed tooth. It can also be used to cover a discoloured or misshapen tooth, functioning much like a natural tooth once fixed with a crown.

The process of getting a dental crown typically involves two visits to the dentist. During the first visit, the tooth is prepared, and an impression is taken to custom-make the final crown. A temporary crown may be placed until the permanent crown is ready. The permanent crown is then placed on the tooth during the second appointment.

A dental crown may be recommended in the following situations:

  • To restore a damaged or weakened tooth due to decay, cracks, or large fillings
  • Following a root canal treatment to protect the fragile tooth
  • When a tooth is misshapen or discolored
  • To support and hold a dental implant in place
  • As part of a dental bridge or tooth implant procedure

A dental crown is a common and safe procedure used to protect, cover, and restore the shape of damaged or weakened teeth. It is custom-made to match natural teeth and can be crafted from various materials based on individual needs and preferences.

Bridges

Bridges are a solution for replacing one or more missing teeth by affixing an artificial tooth to the natural teeth on either side of the gap. Unlike removable dentures, bridges are permanently cemented onto the teeth and cannot be taken out.

There are three primary types of bridges:

  1. Fixed Bridge: This type involves two crowns connected to replace one or more missing teeth.
  2. Cantilever Bridge: A bridge connected to one tooth to replace a missing tooth.
  3. Maryland Bridge: Specifically used to replace a lateral incisor or lower incisor, this bridge is a conservative, semi-permanent technique where a missing tooth is replaced by bonding a metal (or porcelain) ‘wing’ onto the back surface of an adjacent tooth.

Under local anaesthetic, the tooth is shaped to allow room for the crown to fit. An accurate impression is taken using a soft gel-like material and sent to a dental technician. It usually takes two to three weeks for the dental technician to fabricate a crown or bridge. During this period, a temporary crown is placed on the prepared tooth/teeth for protection.

At the second appointment, the crowns or bridges are permanently cemented onto the natural tooth.
