When is a dental crown necessary rather than a filling?

A filling is generally suitable where a significant amount of healthy tooth structure remains. A crown becomes necessary when damage or decay is more extensive and a filling would not provide adequate strength or coverage long term. Teeth weakened by large existing fillings, fractures or root canal treatment are often at greater risk without the additional protection a crown provides. The decision is based on a clinical assessment of the tooth, and your dentist will explain the reasoning behind their recommendation.

How long does it take to get a dental crown?

Traditional crowns typically require two appointments — one to prepare the tooth and take an impression, and a second to fit the permanent crown once it has been fabricated. A temporary crown is placed in the interim to protect the tooth. Where CEREC technology is available, a same-day crown can be designed, milled and fitted in a single visit, removing the need for a temporary restoration and reducing the overall time commitment for the patient.

Can a crowned tooth still get decay?

While the crown itself cannot decay, the natural tooth structure beneath it can still be affected if bacteria penetrate the margin where the crown meets the tooth. Decay developing beneath a crown can be difficult to detect without regular examinations and X-rays, which is why routine check-ups remain important even after a crown has been placed. If decay is found beneath a crown, it will typically need to be removed to allow the decay to be treated before a new restoration is placed.

Dental Crowns in Mareeba | Mareeba Dental Centre

A dental crown is a tooth-shaped restoration that fits over the entire visible surface of a tooth, restoring its shape, strength and appearance. They are commonly recommended for teeth that have been significantly weakened by decay, fracture or previous dental work, where a filling alone would not provide adequate support. At Mareeba Dental Centre, we assess each patient carefully to determine whether a crown is the most appropriate solution, taking into account the condition of the tooth and the patient's overall oral health.

Crowns can be fabricated from a range of materials including porcelain, gold blended alloy, ceramic and porcelain-fused-to-metal, each with different functional and aesthetic considerations. At Mareeba Dental, we have the CEREC Technology to offer same-day crowns with most treatments, this may depend on the type of crown required.

We discuss the available options with patients during the planning stage so the most suitable material can be selected. To find out whether a dental crown may be appropriate for you, call our team on (07) 4092 4277.

When planning a crown treatment, the condition of the underlying tooth structure is one of our primary considerations. A crown needs sufficient healthy tooth structure to bond to, and where this is compromised, additional treatment may be required before a crown can be placed. A crown may also be recommended following a root canal treatment, where the tooth has become more brittle and is at greater risk of fracturing.

Where appropriate, we discuss the role CEREC technology can play in delivering same-day crown restorations for suitable cases, reducing the number of appointments required.
