Dental Crowns North Ryde and Macquarie Park

We offer affordable dental crowns here in Macquarie Park

When a lot of tooth structure is lost, or the area being treated needs something strong to withstand a lot of pressure, a Dental Crown or ‚Äėcap‚Äô is placed on the tooth. They act as helmets for the tooth underneath that is weaker so you can continue to eat and chew on it. They are designed to be strong and to look like a tooth in the mouth.

A dental crown is a tooth shaped cap to cover the tooth. Its main function is to  restore the size, shape, strength as well as improve appearance of the tooth. When they are cemented, it covers the entire visible part of the tooth from the gums upwards.

There are multiple reasons why you would need a dental crown. Some of these reasons include:

  1. A large cavity where there is not a lot of tooth structure left
  2. Prevention of vertical cracks running further into the tooth
  3. Protecting the weaker tooth that has had Root Canal Therapy
  4. An implant has been placed
  5. For a bridge to be placed where there are missing teeth
  6. Improve the colour and shape of a restoration that is in your smile

To find out more precisely you need a Dental Crown, please contact our office at North Ryde Dentistry from an assessment.

Dental crowns can be made with different types of materials. This ranges from ceramics, metal alloys, porcelain or a combination such as porcelain fused metal crown. They are made to look like a tooth with the aim of them being comfortable for you to eat, chew and smile.

The decision on the material would require us to consider where it is located, the function of the tooth, how the gums are around it, what you would like as well as whether it is in you smile. These discussions will be made prior to the Dental crown being placed with you.

There are stainless steel crowns which are prefabricated and used on permanent teeth as temporary device. There are also metal crowns that are best to protect against biting and chewing. They are also known to be the longest to use before it starts to wear down. You may also find the porcelain-fused-to-metal dental crowns. They can look more closely like the adjacent natural teeth, but they easily chip off or crack. They are great for front and back teeth.

The all-resin dental crowns are cheaper than the other types but they easily wear down, faster than the porcelain-fused-to-metal kind. It is more prone to fractures. The all-ceramic or all-porcelain is good for those who have allergies to metal. The downside is that they are not as strong as the porcelain-fused-to-metal as well.

You can also find digitally constructed dental crowns and these are called Zirconia or milled crown. They are produced with the use of software and hardware inside a dental lab.

  • Emax Crown

One of the most used material for dental crowns to date, Emax Crowns are made from a single block of lithium disilicate that is then cut and designed to form the crown. A very good material for its strength as well as ability to look tooth-like due to its translucent properties as well as ability to be layered, stained and cutback to match adjacent teeth.

With our in-house CAD/CAM machine, at North Ryde Dentistry we can complete your treatment with the custom-made crown within one appointment.

  • Zirconia Crown

Zirconia crowns are made of zirconium dioxide, a form of ceramic that is very rigid and strong that can withstand a lot of pressure. They are very durable to the conditions of the mouth and the day to day actions of chewing and eating.

The only disadvantage with them is that they can stand out in the mouth. Though they are made to be tooth coloured, it lacks the translucency that natural teeth has and can sometime show a slight metallic tinge.

  • Porcelain Fused Metal Crown

Porcelain Fused Metal Crowns are crowns that are trying to combine the benefits of a metal crown and a porcelain crown together, with the strength from the metal and the aesthetics of the porcelain to create a durable and tooth-like crown.

There are some disadvantage with it as the combinate of these materials do make the crown a little bulky looking and sometimes a ‚Äėblack ring‚Äô can be seen near the gum line as the metal lining can be seen. The porcelain layer of the crown can also chip over time but in areas where aesthetics is not the main concern, these crowns may be the right fit for you.

  • Gold Crown

Gold crowns are made of gold alloy, a mixture of metals, that is very resilient to wear and very compatible with the conditions in our mouths. They can be made to a tooth like shape however, the gold colour may not be to everyone’s taste. Despite this, they are very durable is a popular for crowns.

Dental crowns can last on average 5 to 15 years depending on the home care and use of the crown. Things that can cause them to not last as long include grinding, clenching, dental decay, gum disease and other mouth related and lifestyle factors.

We highly recommend that you see us from routine hygiene maintenance visits for these conditions to be monitored or managed before your crowns and teeth are affected.

The longevity of dental crowns depend on a number of factors such as:

  • The type of material used to manufacture the crown
  • How well it was made
  • Biting forces the crown will be subjected to
  • Oral hygiene
  • Parafunctional habits (such as grinding)

It is common for crowns to last 7+ years with good maintenance. As with any restorative material placed on teeth, it is important to have regular check-ups to ensure they last a long time, trouble free.

Depending on what type of crown is placed, one or two visits may be required.

In Dental Crowns that require a single visit or same day crowns, also known as CEREC crowns:

  1. The tooth will be prepared by the dentist, removing any decay and the outer structure for the crown to sit on. The dentist may also be building up parts of the tooth with filling material.

  2. A scan will be made with our CAD/CAM machine designed with the dentist to fit into your mouth

  3. Our CEREC machine will then begin to mill the crown from a single block of ceramic

  4. The crown will be fitted and placed in the mouth with adjustments

For Dental Crowns that require two visits:

  1. The tooth will be prepared by the dentist, removing any structure affected by decay and the outer layer. The tooth may be built up by the dentist with filling material

  2. An impression with a putty material will be taken and sent to the laboratories for the crown to be designed and made with the specific dental material

  3. A temporary crown will be placed over the prepared tooth. This temporary crown is designed to help prevent sensitivity to hot and cold during the time it takes for the real crown to be made. However, it is a weaker material as it is a temporary material. We will usually remind you to not chew or eat anything firm for the meantime.

  4. The crown will be made and sent back to us from the laboratories.

  5. We see you for the second appointment to fit and adjust the crown as needed before cementing it firmly in place.

Some sensitivity can be felt after a crown is placed for a couple of weeks as it slowly adjusts in the mouth but it should settle down over a couple of days after treatment.

These steps may vary slightly depending on the type of material used. A good discussion with our dentist before these appointments are highly encouraged.

At North Ryde Dentistry, our dental crown’s starting price is from $1,450 with a 5-year limited warranty! Depending on the material, prices may vary.

A 30% discount for your first dental crown visit is currently available on our website special.

Taking care of your crown is very similar to taking care of our teeth ‚Äď good brushing twice a day and daily flossing between the crowns and teeth are highly encouraged. Avoiding chewing on hard and firm foods, like ice, or hard objects, pencils, fingernails, and pens. This is especially important for dental crowns that are tooth coloured.

Seeing us at North Ryde Dentistry regularly also is one of the best ways to take care of your Dental Crown as we can monitor it over the regular visits.

Crowns, though are a very good treatment option, can also experience issues. Depending on what happens, at North Ryde Dentistry we will help you investigate what is wrong with your crown.

Some of the problems that can develop include:

  1. Dental Decay/Tooth Decay underneath the crown ‚Äď this can still occur with crowned teeth. In order to treat, we would need to remove the old crown, treat the tooth decay underneath and then place a new crown over.

  2. Chipped: Depending on the size of the chip, some can be repaired or left alone. However, some will be required to be replaced entirely with a new crown that may need to be made of a stronger material.

  3. Loose/fallen off: Some crowns over time can be loose or fall off. If so, please bring the crown with you and visit us as there are times, we can simply cement it back on if there are no issues underneath. However, some crowns can fall off due to other reasons with the tooth.

There could be many reasons as to why the tooth will look dark around the crown. Reasons such as:

  • Decay
  • Previous Root Canal Therapy
  • Metal Banding of the Porcelain fused Metal crown and more

Please visit us for a proper assessment on what is happening. It may involve re-treatment where the old crown is removed and a new crown is placed.
