What is a CROWN?
When your tooth becomes severely decayed, has large filling, fractures or cracks it loses strength and support. The treatment then to save your tooth will require more than a dental filling, instead a dental crown is recommended. A dental crown can be made of gold, porcelain-fused-to-metal, or all porcelain. It helps embrace your remaining tooth structure and is designed to look like a healthy and natural tooth.
A dental crown is in essence a «cap» designed especially for the individual tooth that has lost significant support encasing it in protective material to prevent further damage such as “cracks”.
Why do I need a crown?
- A) Decayed teeth
- B) Teeth with Root Canal
- C) Broken or fractured teeth
- D) Esthetic improvement
- E) Large or broken fillings
You will find a detailed explanation of each of the listed reasons above which may be helpful to answer some of your questions depending on your situation.
A) and B) If the loss of tooth support is due to severe caries that has caused dental pain, then a root canal treatment will be required prior to placing a crown. If you don’t put a crown after the root canal treatment, the tooth may fracture below the gum line making its restoration difficult and in some cases the fracture may continue to the dental roots. This is called a vertical root fracture and your tooth will need to be extracted. A dental crown can help save the tooth from vertical cracks.
C) If the loss of tooth support is due to a crack in the tooth, then depending whether there is pain or not and the size of the crack, a crown may be the right choice. Crowns provide you the ability to save as much of the tooth structure as possible and prolong the longevity of your tooth. Like all restorations, crowns can last a very long time but they eventually may need to be replaced.
D) and E) Dental crowns can also be indicated in situations where very large fillings have been placed and again tooth support is compromised. If you have many large fillings in your front teeth and you would like to improve the appearance then a porcelain dental crown will restore your smile to a better esthetic and functional outcome.
