A crown, sometimes referred to as a “cap”, is a dental restoration individually crafted to completely cover or “cap” over your natural tooth. It can be used for aesthetics and to reinforce the strength of a tooth with cracks, large fillings or after procedures such as Root Canal Therapy (RCT).
Teeth that have completed root canal therapy no longer have their own nerve and blood supply, and are therefore very brittle. Without a crown, a root canalled tooth is highly susceptible to breaking. If the tooth breaks below the gum and bone level, unfortunately there is nothing that can be done to restore or save this tooth, the tooth must be removed. This is very devastating for patients as they have spent a lot of time and money trying to save the tooth, which now has to be removed. The other reason a crown is important over a root canalled tooth is; studies have shown that teeth that have completed root canal therapy have a high chance of success when they have good coronal seals. This means the seal over the access cavity in the tooth’s biting surface is optimally sealed with a crown.
Crowns are also extremely useful for broken, cracked or teeth with large fillings. In these teeth a crown could actually help to avoid a tooth needing root canal therapy. A crown will help to reinforce the strength of the tooth and protect it from breaking down further, idealing avoiding the need for root canal therapy or extraction. Once the crown is placed the aim is to enable you to chew normally again.
The material of a crown can be Gold, Porcelain, Porcelain fused Gold, Zirconia, Porcelain fused Zirconia, or Emax to name a few. The type of material used for your crown will depend on your individual treatment needs. The clinicians at Admire Dentistry are extremely knowledgeable, and work closely with their dental technicians to ensure you have the right crown for your needs.
Once a crown has been permanently cemented it requires optimal and regular at home oral hygiene care, as well as a comprehensive check-up and clean every 6 months with your dentist. At the time of placement your dentist will show you how to effectively clean around your crown. Each patient will also receive a goodie bag containing floss, piksters, a tooth brush and information. If a crown is not taken care of, decay can creep under the crown compromising the integrity of the crown and tooth. This could lead to you needing a new crown, or losing the tooth altogether. It is very important to take care of a crowned tooth just as you would a natural tooth.
Our Frequently Asked Questions
If a tooth is heavily broken down and the amount of filling material is greater than the remaining tooth structure, a crown is recommended. In this case, it is a preventative treatment to avoid further breakage of the tooth and, in many cases, avoid a root canal.
