Crowns & Bridges Brisbane City

Restore form and function to your smile

A dental crown is a tooth-shaped “cap” that is precision made to cover a damaged single tooth. Crowns are securely fixed in place, unlike removable devices such as dentures, which you take out and clean daily. Crowns are cemented onto existing teeth or implants and look and feel like a natural tooth.

Bridges, on the other hand, are commonly used to replace one or more missing teeth. Bridges are also securely fixed in place and are used to fill the space of a missing tooth (or several teeth). Bridges do this by fixing an artificial tooth permanently to the adjacent teeth or dental implants. There are many variations of bridge styles, techniques and materials that can be used. Individual factors of age, space size, tooth position, bite position, aesthetics and hygiene will determine the best bridge treatment option for each person.

How do crowns work?

Teeth can become damaged or weakened for a number of reasons such as large fillings, decay, trauma, cracks or root canal treatments. The difference with teeth when compared to bone, is that they cannot heal. Once a tooth has a crack, the only certainty is that it is going to get bigger. For teeth that are significantly weakened, we must strengthen or repair any damage with crown and bridge restorations.

Besides strengthening a damaged tooth, a crown can also 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 to prevent a crack from splitting a tooth
  • Protect a weakened tooth from fracturing
  • Restore an already 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

How long do crowns and bridges last?

The average lifespan of a crown is 15 years, however with diligent maintenance, crowns can last over 20 years! We even have a few regular patients with crowns that were placed in the 1970s. While crowns and bridgework are as permanent as it gets in dentistry, 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. A 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, seeing your dentist and hygienist for regular check-ups and professional cleanings will significantly increase the long-term success of your crown treatment.

To prevent damage to your new crown or bridge, treat them with care and avoid chewing hard foods or taking the top off bottles with them!
