Crowns and Bridges

 

Bridges and crowns are fixed prosthetic devices that are cemented onto existing teeth or implants, by a dentist or prosthodontist. Crowns are used most commonly to entirely cover or “cap” a damaged tooth or cover an implant. 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 discolored or poorly shaped tooth
  • Cover a tooth that has had root canal treatment
  • Gaps left by missing teeth eventually cause the remaining teeth to shift resulting in a bad bite. This can also lead to gum disease and TMJ disorders. Bridges are commonly used if you’re missing one or more teeth. They cover the space where the teeth are missing and are cemented to natural teeth or implants surrounding the space.

 

Types of Dental Crown Materials
There are four different types of materials used for dental crowns:

  1. All ceramic (porcelain-based).
  2. Porcelain fused to metal.
  3. Gold alloys.
  4. Base metal alloys.

Care

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 is to practice good oral hygiene. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. See your dentist regularly for checkups and professional cleanings.

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

Procedure

All ceramic and porcelain fused to metal crowns can be matched to the color of your natural teeth. A bridge is mounted onto a space where teeth are missing and is attached onto adjacent teeth. These teeth, called abutments, serve as anchors for the bridge. As with crowns, you have a choice of materials for bridges. Your dentist can help you decide which is best for you, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost.
