Randwick Smiles is pleased to offer our patients a professional dental crown procedure where your comfort comes first. Our skilled team will ensure that a natural crown is created to complement the rest of the teeth in your mouth.


What Are Dental Crowns?

Dental crowns are created as coverings for your existing teeth. A crown would be used to improve the appearance of a tooth that is decayed or broken. It is used when the area that needs to be filled or covered is too big for a filling. A dental crown can also be used to add protection to teeth to stop them from breaking, or to cover teeth that are very stained, damaged or broken.

Also known as caps, dental crowns can be used to restore the crown (or visible part) of your tooth.


How Does The Dental Crown Procedure Work?

Before your dental practitioner can start working in your mouth he or she must first numb the area. Teeth that have undergone root canal treatments or fracturing may first need to be built up with a filling – to ensure there is enough tooth for the crown to adhere to.

In order to prepare your tooth for a crown, a layer needs to be removed from its outer surface. Your dentist will shave this layer off. The crown that your dentist will create will have the same thickness as the layer that was removed. The exact preparation that needs to be done usually depends on the material your crown will be made out of. The shade of your tooth will be noted so that the new crown matches well with your existing teeth.

Your dentist will then take a cast of the tooth and send it to a laboratory or dental technician who will prepare your crown. Your dentist will ensure the final crown is the same shade as your other teeth, so that it does not stand out.

Once your crown has been created, you will return to your dentist for the fitting. Sometimes, as is often the case with patients who are having dental implants, your dentist can give you a temporary crown to wear, while you wait for your permanent crown to be ready.

A temporary crown should only be worn for a short period of time because the materials they are made of and the cement that is used is not very strong, and unlikely to last for a long time.

Once the permanent crown is ready, your dentist will fix it over your damaged tooth using dental cement. You will test how the crown feels and works and your dentist will check your bite, and ensure the margins of your crown are smooth. Sometimes small adjustments need to be made to ensure optimal comfort.


What Are The Benefits Of Dental Crowns?

Dental crowns can completely alter the appearance of a tooth. They are used most commonly on teeth that are broken, damaged or weakened. They can also be used to improve the appearance of teeth that are misshapen or discoloured.

Your crown may last for 10 to 20 years with good dental care.

Dental crowns can be used for:


Large fillings

If a cavity extends over half of your tooth, or more surface area, it will need to be covered by a crown in order to compensate for the weakness of the tooth structure.

Sometimes teeth that already have fillings will show signs of stress and cracks will become visible around the filling. In this case the filling will need to be replaced by a dental crown.


Root canal treatments

In many root canal treatments, a patient needs to have a crown because the procedure has made the tooth hollow and prone to cracking. In this case the tooth would be reinforced by a dental crown.


Worn or eroded teeth

Patients who grind their teeth or clench their jaws excessively can cause damage and shortening of the teeth. Worn tooth enamel can cause the teeth to soften, and over time this can lead to the collapse of your bite.


Dental implants

Patients who replace their missing teeth with dental implants need to have a crown placed on the abutment in order to close up the gap left behind.


Can Anyone Have A Dental Crown Procedure?

In order for a crown to be a viable solution, there must be enough of your original tooth structure available for the crown to adhere to.


What Are Dental Crowns Made Out Of?

Dental crowns are available in a variety of materials including porcelain, ceramic, composite materials, zirconia, gold alloy, metal alloy or a combination. Each type of material comes with its own set of advantages and disadvantages. It is recommended that you discuss your options with your dental practitioner to evaluate which is the most suitable for you.


Is It Painful To Have A Dental Crown?

Most procedures are performed under anaesthetic so that you can’t feel it. Some patients report some sensitivity and discomfort once the anaesthetic has worn off, but this can be managed using over-the-counter medication.
