Dental Crown

Sometimes a filling may not be the suitable solution to protect the tooth, where there is risk of fracturing! A Crown may be a good alternative.

What Is Dental Crown?

Crowns are dental restorations which fully encapsulate a tooth structure from the outside – just like a motorcycle helmet to motorbike rider’s head.

When Do Teeth Need Dental Crown?

Crown can be done for a few different reasons.
  • To strengthen a tooth
  • To restore the shape of a tooth or to improve aesthetics

  • Prevent painful splitting of the tooth

Studies suggest a high correlation between tooth fracture to large fillings and root canal treated tooth. A study by Larson (1981) determined that fillings that take up 1/3rd of the “intercuspal distance” of a tooth decreased the resistance to fracture by more than 50%.

Geurtsen (2003) found tooth’s risk for fracture increased substantially as the filling approached 50% of its intercuspal distance. Geurtsen’s recommendation was that fillings should not exceed 1/3 to 1/4 this distance.

Depending on how the tooth has fractured, these natural teeth can, occasionally be restored or saved without major consequences. However, prognosis drops significantly when fracture tooth is presented with pain, worse still, a tooth which has already fractured in half can only be removed.

American Association of Endodontists has a great article with animations to better explain the different scenarios and treatment options.

Types of Crown Material

  • All – Procelain crown (Ceramic crown) – Tooth coloured

  • Porcelain fused to Metal – Tooth coloured, however, there is a underlying metal layer.
  • Full Metal – Gold or silver in colour.

Our types of dental prosthesis are all 100% Australian made and therefore we guarantee the material used are 100% compliant with approval by Therapeutic Goods Administration (TGA).

What Happens During Your Crown Appointment

A crown at Alexandra Hills Dental is usually spread across two visits, so you know what to expect from the start. At the first appointment, we numb the area with local anaesthetic, then carefully reshape the tooth so the crown has room to sit flush with your bite. An impression or digital scan is taken and sent to the Australian lab that fabricates your restoration. You’ll leave with a temporary crown protecting the tooth while the permanent one is made.

At your second visit, the temporary comes off, we check the fit, colour match, and bite alignment, then bond the permanent crown into place with dental cement.

A few things worth knowing before you come in:

  • Numbness from the anaesthetic can linger for a couple of hours

  • Avoid hard or sticky foods for 24 hours while the cement sets

  • Mild sensitivity to hot and cold can settle within a few days

  • The bite should feel even, not high, once you’ve adjusted

Call 07 3824 4488 if anything feels off after fitting.

Caring for Your Crown So It Lasts

A crown is built to handle normal biting and chewing, but how long it lasts comes down to daily habits and routine check-ups. The crown material itself won’t decay; the natural tooth structure underneath still can, and that’s usually where problems start. Cement can wash out over the years, gums can recede, and bacteria can creep in around the margin if oral hygiene slips. Looking after the tooth properly is what protects your investment.

Simple habits that keep a crown in good shape:

  • Brush twice daily and floss around the crown margin

  • Book regular hygiene visits with us to catch issues early

  • Wear a night guard if you grind or clench

  • Skip chewing ice, pen lids, or fingernails

  • Cut back on sticky lollies and caramels that can pull at the edge

If your crown ever feels loose, sensitive, or sits oddly when you bite, don’t wait. Ring us on 07 3824 4488 and we’ll have a look before a small issue turns into a bigger one.
