Dental Crowns or 'Caps'

HOME > Crowns

When we are discussing a crown for your tooth it will be because we need to consider improving the strength of your tooth and/or we want to enhance the appearence of your tooth.

What is a crown?
A crown is a covering made to go over a tooth. 
 

Benefits of a crown?

1. Improve appearence
   We can change the color and shape of teeth with crowns
2. Increase strength
   Cracked teeth, root canal treated teeth and heavily filled teeth are all weakened. Using a crown we can increase the strength of a tooth to give you more years of function.

What's involved on getting a crown

A crown is more complex and time consuming procedure than a simple filling for a tooth.
We will explain the process for your particular teeth but if you have more questions please ask.
Possible stages: 

• Assessment - this may involve photos, xrays and/ or moulds of your teeth
• Tooth preparation for the crown - this may be a longer appointment than normal
• Placement of the crown - once made the crown is "fitted" to the original tooth. This may be on another appoinment time if the crown is made by a dental technician

Types of crowns
There are many different types of crowns. Professional skill and experience mean the correct crown is available for your individual tooth requirements.

1. Gold crowns: Advantages include a strong crown with similar hardness and wear property as a natural tooth.
2. Porcelain -over-metal crowns: for situations where color and strenght are important. These are harder than normal teeth
3. Tooth coloured crowns: for situations where color properties are the highest priority. 
4. Metal crowns - prefabricated: these are crowns adapted for deciduous(baby) teeth and are applied in a single visit.

Unplanned complications
During any medical or dental or health treatments it is possible that unplanned complications can occur.

• Breakage of the tooth
  While very effort is made to evaluate teeth before the crown preparation is undertaken it is not possible to detect cracks with radiographs and they may not be seen either. A tooth may crack during crown preparation or can crack later. If a crack occurs during crown preparation the treatment of the tooth may be modified depending on how severe the problem
• Pain or discomfort
  After preparing a tooth for a crown it may feel tender as the anaesthetic wears off. If this discomfort persists for more than 24 hours please let us know. Sometimes a very slight variation to your 'bite' can cause ongoing pain. This may be simply relieved by making your restored tooth 'less high'.
• Nerve dies
  Usually teeth that are crowned have had large or deep fillings (restorations) within them. These teeth are more likely to require root canal treatment (endodontics). If pain persists after preparation for a crown or after a crown is put in place please let us know. The cost of root canal treatment will be additional to the cost of the crown.
• Loose crown
  If your crown or temporary crown feels loose please let us know. When a crown is loose extensive decay of the remaining tooth can occur quite quickly. If the crown is loose we may be able to clean it and re-cement it into place.
• Allergic responses
  Being allergic to gold or porcelain would be very rare. Usually the metal used inside a metal/porcelain crown is a mixture of metals including gold. Sometimes non-precious metals are used in crowns. If you are allergic to any jewelry then please tell us BEFORE we do a crown so we can determine the material of least risk. Allergic response to crowns may take some time to be seen or may develop after a crown has been put in place. It may be seen with increased inflammation or the discoloration of the gingival tissue around the crowns only.

Costs of treatment
Crowns are an investment in time and expensive technology and materials. We will let you know how much your crown will be before we start making the crown.
Extra costs will generally occur if complications happen.
