Here at The Dental Practice, Burwood we treat every tooth with a unique approach.
What is a Crown?
A crown, which is sometimes referred to as a cap, is a gold or porcelain restoration that is designed to completely encase a single tooth. Crowns provide strength and support to a tooth that has become weak. This can be caused by decay, loss of a large filling, if you have sustained a fracture in an accident or undergone root canal therapy, which can result in much of the tooth’s natural structure being lost.
Being highly versatile in their application and natural in appearance has led to crowns becoming the most utilised of all restorative dental solutions.
Placing a crown enables our team to restore the natural function of your tooth and the appearance of your smile. While a crown is often used for rehabilitative treatment, they are becoming increasingly popular in cosmetic dental procedures to help achieve a new straight smile.
As a commitment to excellence in all facets of your care, we insist on using only the highest quality materials to create your restorations, ensuring their strength, longevity and your continued oral health and appearance.
Crowns are needed when a tooth has a significant amount of structural damage and a normal filling would not be adequate. This damage can be caused by decay, trauma or wear. Some examples include:
- Heavily filled teeth that have broken or that are likely to break in the near future.
- Teeth that are heavily decayed and there is insufficient tooth structure to support a normal filling.
- Teeth that show symptoms of microcracking. Teeth with old amalgam fillings often crack around the filling causing pain when chewing. If left, these teeth can eventually break in half.
- Teeth that have had root canal therapy.
- Teeth where damage has affected the appearance. (This is not confined only to front teeth as many people show back teeth when smiling)
- Where teeth are missing completely, dental implants can be placed. The implants function as artificial tooth roots and once healed have crowns placed on them.
- In some people, teeth can wear down to the point where chewing becomes difficult. In these cases, crowns can be used to build the teeth back to their original shape. This restores both appearance and function.
Placing The Crowns
The procedure can vary depending on the situation but in most cases, the tooth is reduced in size by about 0.6mm. A mould is then taken of the upper and lower teeth and sent to our laboratory where the crown is made. With the help of our technician, a record of the colour of your adjacent teeth is taken so the crown can be matched to your teeth. A temporary crown is placed which you will wear until the final crown is made. At this time the temporary crown is removed the final crown fitted and adjusted to fit your bite exactly. It is then cemented with a special adhesive.
When we recommend a crown we always consider your individual needs to ensure the procedure is as pleasant as possible. Any concerns that you have will be addressed before we begin.
Crowns are the strongest possible solution for damaged teeth and if done well should function for many years. They are made to match the colour and shape of your natural teeth.
Definitely not! Broadly speaking, crowns can be classified into 3 main types:
- Full metal– These are placed on teeth that cannot be seen and where the utmost strength is required. They can be made from different materials but we choose either cast gold alloy or milled titanium.
- Porcelain bonded to metal– This is the most commonly used crown. They are excellent for back teeth but are not used as often on front teeth.
- Non-Metal– Over 10 years ago in conjunction with our laboratory, we were among the first to place all-ceramic crowns. These crowns have a vastly superior appearance to conventional crowns. All ceramic crowns are more biocompatible meaning that the body accepts them more naturally.
The ideal choice of the crown will be discussed with you before or at the preparation visit.
A WORD OF WARNING… Many dentists who place cheaper crowns use porcelain bonded to cast non-precious metal and often have them made overseas to save cost. We will never use these types of crowns, as they are inferior in every way.
