A crown is a cap or covering for a tooth. This is used to fix when your tooth is broken or cracked or heavily filled or even if lost fillings.

Crowns come in a variety of materials and the cost varies depending on the chosen material. Our Kallangur dentists can recommend the perfect crown material during your first visit.

Our dentists use their expertise and modern technology to match the new crown to the shape of your existing teeth and their colour.

When would I need a crown?

• Replacement of a large filling
  If your teeth are heavily filled, they may be at risk of fractures. Frequent replacement of fillings can lead to loss of precious tooth structure. Repeated dental treatment on the same tooth may lead to deepening of the filling and subsequent nerve inflammation. To avoid these complications, your dentist may recommend that a crown is constructed before the filling becomes too large and remaining tooth structure is too short to support a crown.
• To stop a tooth from further cracking or fracturing
  If your tooth is showing fine lines and cracks or you occasionally feel sensitivity when biting into sticky or hard foods, your tooth may have a deep crack or may be at risk of complete fracture. This is common for heavily filled teeth, especially where an amalgam filling is in place. Your dentist may recommend a crown to restore the tooth and protect its cusps from splitting apart and may suggest replacing any amalgam with a ceramic restoration.
• To anchor a bridge replacing a missing tooth
  If a tooth is missing or lost, your dentist will discuss the options for tooth replacement. This may involve the placement of an implant or tooth supported bridge. If two or more teeth directly adjacent to the lost or missing tooth are at risk of fracture or are discoloured and need crowns, a bridge may be a good option to replace the missing tooth. When the bridge is produced, a porcelain tooth (pontic) is fused to the two or more crowns on either side and once the crowns are fitted onto the adjoining teeth, the porcelain pontic appears to be emerging out of the gum. A bridge may be a suitable course of treatment for you if you are unable to have an implant due to issues with your overall health or dental health.
• After root canal treatment 
  Root canal filled teeth are prone to fractures, due to the nature of root canal treatment and hollowing out of the tooth in the process. Dentists highly recommend crowning most root canal filled teeth to protect them from fractures and further bacterial infections.
• Cover discoloured or worn teeth
  If you feel that your teeth are becoming more transparent or becoming darker in colour, they may be wearing down. Your dentist will discuss the reasons behind this as it is important that they are addressed first. If your dentist recommends a crown restoration, then this crown will be fabricated to resemble the natural shape and strength of your existing tooth through the use of a ceramic material.
