Dental crowns are sometimes used to restore the function and appearance of a tooth that has been damaged, but they are not always necessary. Our Victoria dentists explain when and why this would be the best option.
What are dental crowns?
A dental crown is a hollow cap that is placed over a damaged or decayed tooth to give it a natural, healthy appearance. The crown should protect the tooth and restore its function while also protecting it from further damage. A dental crown can also be used to cover discoloured or misshapen teeth.
Types of Crowns
Crowns can be made from a variety of dental materials, depending on the type of tooth and the location of the crown in your mouth.
With translucency and natural tooth colour matching, these materials should be the most lifelike on the market. They are, however, more prone to chipping and wear than other materials. As a result, they are only used in a small percentage of cases to replace teeth.
Composite crowns are another material that closely resembles natural teeth in appearance. They are more resistant to chipping than porcelain, but they can easily wear down and stain.
These are made of gold and should be quite strong. They should not wear down or stain like composite crowns, but they do not look natural, particularly on front teeth.
These crowns should look more natural than porcelain or composite crowns. They should be chip and stain-resistant, but the metal may show through due to their placement and construction.
In most cases, a dental crown requires two visits to our office. Your dentist should administer a local anesthetic during your first visit.
To make room for the crown, your damaged tooth will be filed down and an impression taken. This will be used to make your restoration because it will be custom-fitted to your tooth.
Until the permanent crown is ready, a temporary crown will be worn. Your dentist should remove the temporary restoration and replace it with your new permanent dental crown at your next appointment, cementing it in place.
When are dental crowns the best solution?
Crowns aren't always the best choice, and your dentist can assist you in determining what is. The following issues, on the other hand, are fairly common and almost always necessitate the use of a dental crown.
Best Situations for a Dental Crown
