Prosthodonitcs Crowns

Dental bridges replace missing teeth by "bridging" the gap between two remaining teeth. You and your dentist can discuss the different types of bridges to choose the best option for you:

  • Traditional bridges, also called fixed bridges—the dentist creates a pontic, or false, tooth with a dental crown on either side. The crowns are fitted over the remaining teeth to hold the false tooth in place.
  • Resin bonded bridges—the pontic tooth is fused to a metal band. The metal band, in turn, is bonded to the back of the remaining teeth with white resin cement.
  • Cantilever bridge—dentists recommend this bridge when there are only teeth on one side of the gap. While traditional bridges have a crown on either side of the pontic, cantilever bridges consist of two side-by-side crowns and only one is connected to the pontic.

To design a bridge, a dentist must first shrink, then reshape the teeth to make room for the crowns. He or she then makes a mold of the teeth. This mold is then sent off to a laboratory, where the actual crowns and bridge are made.

With proper oral hygiene, bridges can last up to ten years. However, improper or infrequent brushing and flossing, irregular dental visits, and excessive sugar and starch intake can all bring untimely damage to the bridge.

Dental Crowns

Dental crowns, also known as dental caps, cover damaged or discoloured teeth. Crowns cover the entire tooth, starting at the gum line. They are usually made of gold, porcelain, or a combination of both.

Though crowns can be used to improve the appearance of a tooth, they are not primarily cosmetic devices. Dentists recommend crowns to protect or strengthen weakened teeth, or to restore a disfigured tooth to its original shape. "Capping" a tooth requires buffing away part of a tooth to make room for the crown, so dentists often discourage it as a cosmetic method unless the teeth are damaged.

Crowns strengthen teeth by binding the sides of the weakened tooth together, much the way a splint holds together a broken bone. Large fillings taking up over a third of the tooth may weaken that tooth over time; crowns are often used in cases where such weakened teeth threaten to break.

The "capping" procedure takes place under anaesthetic. Because the crown is about two millimeters thick, the dentist first shaves this same amount off your existing tooth to avoid awkward-looking, oversized teeth. The dentist will also re-shape your tooth into a form upon which a cap can easily sit. He or she will then make a replica of your tooth. Usually, this replica will be a putty mold. This mold is then sent to a laboratory, where the crown will be made based on this mold. In the case of a porcelain crown, the dentist will choose a shade close to the colour of the surrounding teeth. You will return about two weeks later to have the crown fitted and, once both you and your dentist are satisfied with the "look and feel" of the crown, cemented over your original tooth.
