Dental Crowns

A crown is a covering that goes completely around a tooth. Usually made from pure porcelain the crown is fused to a metal substructure, often gold or from porcelain only.

Crowns are used to support a tooth and decrease it’s chances of fracturing. This is especially true when a tooth has been heavily filled or root filled and the remaining tooth is weak or there is not enough tooth structure left to hold in a filling. Crowns are also used for aesthetic reasons when we need to change the shape or colour of a tooth.

The length of time it takes to prepare a tooth for a crown depends on the difficulty of the situation. Usually a minimum of one hour is required in the dental chair. An impression (mould) is taken of the prepared tooth and sent to a Dental Technician who takes approximately two weeks to construct the crown. A temporary crown is made of plastic and is placed on the tooth for this time, so that you can eat properly and the tooth looks normal.

It takes approximately 30 minutes to cement in the new crown on the next visit.

Generally a crown will only fail if decay reaches the teeth around the crown OR the rest of the mouth changes, (such as teeth get darker, but crown stays the same).

If supported by healthy teeth, your crown should last for approximately ten years. Like always it is important you maintain regular dental check ups to catch potential problems early.

Dental Bridges

Missing teeth are common in adults, and at Amazing Smiles, we can fill these missing teeth with porcelain bridges.

Porcelain bridges are porcelain teeth made up to fill the gaps of missing teeth in the patient’s mouth.

The missing teeth can be at the front or back, involving one or more teeth. However, the difficult part is how the dentist anchors these artificial teeth without falling out.

Dental bridges are bonded to existing teeth after preparation by your dentist based on the number of artificial teeth needed.

A three unit bridge is the most common bridge, which involves preparing the two adjacent teeth to a stump. The dentist will make an impression and create a temporary bridge during your appointment.

On the second visit, patients come back to have the permanent porcelain bridge cemented two weeks later.

4 Types of Dental Bridges

1) Traditional Dental Bridge

Traditional dental bridges are the most commonly used type out of the four options.

Traditional dental bridges are used when natural teeth surround a missing tooth, resulting in a gap. These bridges consist of a ‘Pontic’, a term used for the middle artificial teeth. Pontic teeth are held in place by dental crowns used to cover the adjoining teeth as anchor points.

However, the downside of using traditional dental bridges is that your dentist will require modifying the adjacent teeth to support the adjoining dental crowns.

2) Cantilever dental bridges

Cantilever dental bridges differ in structure from traditional dental bridges since only one tooth supports the pontic.

Dentists do not recommend Cantilever dental bridges for the back of the mouth that sustain more pressure while chewing and clenching your jaw.

Like traditional dental bridges, your dentist will remove and reshape the tooth that supports the dental crown.

3) Maryland Bridges

Maryland Bridges are similar to traditional dental bridges. However, a metal or porcelain framework is used rather than your dentist needing to reshape the surrounding teeth to support the dental crowns.

Instead, the framework is bonded to the back of the adjacent teeth to support the ‘pontic’ tooth.

The benefits of Maryland Bridges are that neighbouring teeth do not require reshaping. Secondly, it’s cost-effective compared to a traditional dental bridge.

Unfortunately, they are not as durable compared to traditional dental bridges and, when built with a metal framework, can cause tooth discolouration. The strength and durability of Maryland Bridges rely on the strength of bonding materials.

4) Dental Implant Supported Bridges

Instead of using natural teeth to support a dental bridge, cosmetic dentists can also use dental implants.

Implant Supported Bridges is a surgical procedure recommended for patients missing several adjoining teeth. As a result, they cover more significant gaps that require more support.

Dental implants are the optimum choice for missing teeth but are an invasive procedure requiring multiple visits and recovery periods. Dental implants are renowned for their strength and durability. The titanium screw helps stimulate bone growth, similar to the tooth of a natural tooth.

What are the steps of a Dental Crown or Dental Bridge Procedure?

Dentists begin by shaping your teeth to receive a crown or bridge. During this same appointment, patients select the particular ‘shade’ (colour) of their new teeth.

After this, your dentist takes an impression of the prepped teeth. Teeth Impressions are used as a structural reference to design teeth ceramics.

A dentist will apply temporary crowns or bridges to cover ‘re-shaped’ teeth. During this phase, a local dental laboratory designs and builds the tooth restoration using innovative technologies.

Dentists will remove the temporary restoration and cement the ceramic crown or dental bridge with unique bonding materials.

Dental technologies have advanced drastically over recent years allowing dentists to produce better end results faster.

We are very fortunate to have specialised CAD/CAM supplies known as a CEREC.

CEREC equipment allows us to manufacture crowns and bridges on site. CEREC machinery eliminates the need for temporisation as the crown/bridge can be prepared, manufactured and fitted all in one appointment.

When is a dental crown needed?

The most common reasons why a dentist may recommend a crown:

  • Fixing a chipped, cracked or damaged tooth
  • Support a weakened tooth
  • Cover a tooth that has had root canal treatment
  • Support a dental bridge, which will fill an empty gap of a missing tooth
  • Cover and protect a hefty filling of a fixed tooth from a dentist
  • Cover a dental implant
  • Improve the aesthetic shape of a tooth
  • Fix a dead tooth, which is often identified as a blackened tooth

How long will my crown last and do they need to be replaced?

It is reasonable to expect crowns and bridges to last ten to fifteen years. Occasionally dental crowns and bridges loosen or fall out. To protect your crown or bridge, you need to maintain good oral hygiene.

Healthy teeth and gums require brushing twice daily with fluoride toothpaste and flossing once a day.

Failure to adequately maintain your teeth and gums puts your crowns and bridges at risk of becoming undermined by dental disease.

Regular check-up and cleans by your nearest Dentist is essential to help maintain the health of your underlying teeth and to examine the status of your artificial restorations.

How much is a dental crown?

The average cost of a dental crown is approximately $1,200. However, prices may vary because patients’ teeth and needs are individually unique. Dentists may recommend additional treatment for optimum oral health and aesthetic results.

Dental Crown Procedure

There are several factors taken into consideration for the dental crown process, including:

  • Aesthetic planning of the crown with the patient
  • Tooth reshaping of natural teeth to support the crown
  • Advanced dental technologies needed to design and produce the crown in a dental laboratory
  • Cementing of the completed crown onto the previously prepared tooth

How much is a dental bridge for your teeth?

A 3 unit porcelain bridge costs approximately $3,400 (please note that teeth are all unique in shape and the patient’s underlying condition, prices may vary).

A Maryland Bridge is a simple porcelain bridge where the anchor teeth have very minimal preparation. Instead, the metal or porcelain framework adheres to the back of neighbouring teeth. This conservative treatment costs approximately $1,900 (please note, as teeth are all unique in shape and requirements between patients, prices may vary).

Implant Supported Bridges are priced differently as the procedure of each dental implant has to be taken into consideration for treatment plans. Individually and excluding the cost of the bridge, each dental implant costs anywhere between $4,500-$5,500.

Are dental crowns covered by private health?

Dental crowns and bridges are claimed under policies with “Extras” or “Hospital” cover. Since all private health packages and the amounts they cover differ, it’s best to confirm with your provider before treatment. Most insurers consider crowns as “major” dental treatment. Primary dental treatments often include services such as root canals, crowns, dentures and veneers.

Our team is happy to assist with any enquiries if you’re seeking advice.

Is there a difference between a tooth cap and tooth crown?

No, both refer to the same method of dental treatment. That is a ceramic artificial tooth that covers the entire tooth.

Can tooth under crown decay?

Unfortunately, a natural tooth underneath a dental crown or bridge can still be affected by bacteria. Such bacteria can cause cavities or tooth decay due to the gradual build-up of tartar and plaque.

As a result, after a dentist has administered a crown or bridge, it is essential to maintain good oral hygiene and routine dental visits.

Decay could be unnoticeable or undetected underneath a crown or bridge, so regular x-rays upon check-up and clean vital.

To protect the underlying tooth between dental visits, it is important too;

  • Floss once a day
  • Regularly brush at least twice a day
  • Use antiseptic mouthwash

Unfortunately, if you’re experiencing pain underneath a crown, this can indicate a sign of decay or infection.

Treating tooth decay can be fixed with a dental filling.

Dentists will closely examine the current state of your crown to help identify how bacteria may have travelled through the crown and onto the natural tooth.

Crowns may become damaged over time, fracture, or become loose, leading to bacteria being trapped and damaging the underlying tooth.

In most severe cases, if left untreated, a patient may require root canal therapy to help treat the pulp of the toot. Otherwise, tooth extraction may be necessary for situations where the infection has travelled extensively throughout the tooth and is beyond saving.

Are there disadvantages to having a crown or bridge?

Crowns and bridges can drastically improve oral health and cosmetic issues of teeth. The average dental crown may last anywhere between 5-15 years with good oral hygiene. Please take into consideration that dentists can not predict what you may consume, chew, and how you maintain your teeth during this period, which can influence the longevity of dental ceramics.

There may be a few disadvantages to a crown or bridge like any other procedure.

  • A dentist has to file down and reshape the natural tooth, which will support the underlying crown.
  • A crown may fracture or chip like a natural tooth with enough pressure.
  • The dental cement that holds a crown may deteriorate and soften over time for unforeseen reasons. As a result, this may allow bacteria to build underneath the crown, which can eventuate into cavities or decay.
  • Some patients have become more sensitive to hot or cold temperatures in foods.

What color crowns should I get?

Dental Shade Reference

Your cosmetic dentist will meticulously select which (shade) colour crown or bridge will match your natural teeth. It’s essential to match the ceramic to adjacent teeth so that, the crown or bridge is unnoticeable, particularly under varying light.

What are Pontics Teeth?

A pontic is the fake artificial tooth of a fixed dental bridge or partial denture. Pontics are either made of ceramic or porcelain with metal.

Pontics are made as a single prosthetic and have a similar appearance as a natural tooth along the gum line.
