Crown and Bridges

crown_and_bridgeDental Crowns

A crown is an artificial restoration that fits over the existing tooth thus making it h2er. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function.

Your dentist may recommend a crown to:

  • Replace a large filling when there isn’t enough tooth remaining
  • Protect a weak tooth from fracturing
  • Restore a fractured tooth
  • Attach a bridge
  • Cover a dental implant
  • Cover a discoloured or poorly shaped tooth
  • Cover a tooth that has had root canal treatment

What is a crown made of?

Crowns can be made of a variety of different materials and new materials are being introduced all the time. Some of the most popular options:

  • Porcelain bonded metal (PFM) : A precious or non-precious metal base is made and then porcelain is applied in layers over it.
  • All-ceramic crowns : this modern material is metal free. It can give the strength of a bonded crown and the appearance of a porcelain crown. This makes it suitable for use in all areas of the mouth.
  • Gold alloy crowns : gold is used with other metals to increase its strength, which makes it a very hard-wearing restoration.

How is a crown prepared?

The dentist will prepare the tooth so it is the ideal shape for the crown. This will involve removing most of the outer surface, and leaving a h2 inner core. The amount of the tooth removed will be the same as the thickness of the crown. You will need to have at least two (2) visits. The first visit is generally focused on tooth preparation, the impressions is taken, the shade matched and the temporary crown fitted. The second is to fit the permanent crown. There will usually be about 1 to 2 weeks in between appointments.

How long will my crown last?

How long your crown lasts depends on how well you look after it. The crown itself cannot decay, but decay can start where the edge of the crown joins the tooth. Therefore, to prevent decay affecting the crown, it is important to keep this area just as clean as you would your natural teeth.

Dental Bridges

These days there is no need to suffer from embarrassing gaps in your teeth, or to put up with the inconvenience of dentures. A dental bridge may well be the answer to your problems, providing a realistic-looking replacement which is permanently fixed in your mouth and you brush to clean just like your other teeth.

Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space.

Most often, the two neighbouring teeth (one on each side) will need to have crowns fixed onto them. After reducing the tooth/teeth, your dentist will take an impression to provide an exact mould for the bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the colour of your existing teeth.
