Crown and Bridges

What are Dental Crowns and Tooth Bridges?

Both crowns and most bridges are fixed prosthetic devices. , Crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.

How do Crowns Work?

A crown is used to entirely cover or “cap” a damaged tooth. 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 following conditions:

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

How do Bridges Work?

A bridge may be recommended if you’re missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite.

The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
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. Your dentist can help you decide which to use, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost.

How are Crowns and Bridges Made?

 

 

Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, your dentist will take an impression to provide an exact mold for the crown or bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the color of your existing teeth.

A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth.

How Long do Crowns and Bridges Last?

While crowns and bridges can last a lifetime, they do sometimes come loose or fall out. The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene.

Bridge can lose its support if the teeth or bone holding it in place are damaged by dental disease. Keep your gums and teeth healthy by Brushing with fluoride toothpaste twice a day and flossing daily. Also see your dentist and hygienist regularly for checkups and professional cleanings.

To prevent damage to your new crown or bridge, avoid chewing hard foods, ice or other hard objects.

  1. Brush after eating and before bedtime around the crown with a soft toothbrush, especially where the crown meets the gum line. At the gum line harmful bacteria can be harbored to cause decay and gum disease.
  2. Floss at least once to twice a day. Use the proxy brush or floss threader to remove plaque under and around these areas to maintain good oral hygiene. Buildup of food debris and plaque on your teeth and gums can become infected.
