Crowns & Bridgework

CROWNS

Crowns are the treatment of choice:

  • To repair and rebuild badly broken down teeth
  • To improve the esthetics of misshapen teeth or worn teeth
  • To improve esthetics of badly stained teeth

Crowns are designed to look and feel like your natural teeth.

The following sequence of images illustrates the crown placement process:

Front View of tooth to be crowned. Observe cracks and decay.
Tooth has been prepared to accept the replacement tooth, made of porcelain (and sometimes a thin layer of metal for support). The tooth is prepared with a slight taper to help secure the crown.
The new crown is being put in place. Observe how the carefully prepared replacement will fit under the gum tissue to hide the junction between tooth and crown.
The crown is cemented into place using special dental adhesives. The objective of this procedure is for final crown to look as natural as possible and feel like an ordinary tooth.

FIXED BRIDGEWORK

Fixed Bridgework is the treatment of choice: ·

  • To replace one or more missing teeth
  • To join together (splint) teeth that are mobile from periodontal problems
  • To re-establish function of worn down and damaged teeth

A bridge is a prosthesis which uses an artificial tooth to fill in the gap where teeth are absent. Fixed bridges are cemented on top of the adjacent teeth. The adjacent teeth need to be crowned to provide an anchor for the artificial tooth or teeth.

It is important that you realize that each crown on the bridge will be joined so that you will no longer be able to floss through each tooth, but instead you will need a floss threader that will allow you to place the floss between and under the bridged teeth. Fixed bridges feel and look more natural in your mouth than a removable appliance.

Teeth adjacent to the extracted or missing tooth are prepared for crowns. (see above)
The fixed bridge is cemented in place. The surrounding crowned teeth provide a strong support for the replacement tooth

REMOVABLE BRIDGEWORK

A removable bridge, also known as a removable partial denture is anchored and supported around the adjacent wires, clasps, or attachments.

Disadvantages of a Removable Partial Denture (RPD) vs. Fixed Bridgework

  • A removable partial denture can cause excess wear and tear on the supporting teeth.
  • The clasps on the RPD are made of metal and are visible when supported by the teeth and show up in the smile.

Advantages of Removable vs. Fixed

  • Treatment time is short
  • Less expense

Conclusion

Fixed bridges feel and look more natural in your mouth than a removable appliance.
