A root canal is a procedure designed to save a severely damaged or infected tooth. But what happens when that tooth already has a crown? Undergoing a root canal on a crowned tooth presents a slightly more complex scenario, but it's a common and often successful procedure. This comprehensive guide will explain the process, potential complications, and answer frequently asked questions.
What Happens During a Root Canal on a Crowned Tooth?
The process largely mirrors a root canal on an uncrowned tooth, but with an extra step. The dentist will begin by carefully removing the crown to access the infected tooth structure. This requires precision to avoid damaging the surrounding healthy tooth. Once the crown is removed, the dentist proceeds with the standard root canal procedure:
- Access Cavity: An opening is created in the tooth to expose the pulp chamber.
- Pulp Removal: The infected or damaged pulp (the soft tissue inside the tooth containing nerves and blood vessels) is carefully removed.
- Root Canal Cleaning and Shaping: The root canals are meticulously cleaned and shaped using specialized files to remove any remaining infected tissue and debris.
- Obturation: The cleaned canals are filled with a biocompatible material (usually gutta-percha) to seal them and prevent reinfection.
- Temporary Filling: A temporary filling is placed to protect the tooth until the permanent restoration is applied.
How Long Does a Root Canal on a Crowned Tooth Take?
The duration of a root canal on a crowned tooth varies depending on the complexity of the case. Simple cases might be completed in a single appointment, taking approximately 1-2 hours. More complex cases, such as those with curved or multiple root canals, may require multiple appointments, extending the total treatment time.
Will My Crown Need to Be Replaced After a Root Canal?
Yes, your crown will almost certainly need to be replaced after the root canal. The process of removing and replacing the crown ensures a proper seal to protect the treated tooth from further damage and infection. Your dentist will likely take new impressions of your teeth to create a new, custom-fitting crown.
Can a Crowned Tooth Still Need a Root Canal?
Absolutely. Even with a crown protecting the tooth's outer surface, the inner pulp can still become infected or damaged due to:
- Deep decay: Decay that penetrates beneath the crown.
- Trauma: A significant blow to the tooth can damage the pulp even if the crown remains intact.
- Cracked tooth: A crack extending beneath the crown can compromise the pulp.
- Previous poor restoration: A poorly fitting crown can lead to leakage and subsequent infection.
What are the Risks and Complications of a Root Canal on a Crowned Tooth?
While generally safe and effective, root canal treatment on a crowned tooth carries some potential risks, including:
- Crown fracture during removal: Though rare, the crown can fracture during removal, requiring additional restorative work.
- Root perforation: A small hole can accidentally be created in the root during the procedure.
- Reinfection: Despite meticulous cleaning and filling, there's a small chance of reinfection.
What is the Cost of a Root Canal on a Crowned Tooth?
The cost varies greatly depending on several factors, including location, the dentist's fees, the complexity of the procedure, and the need for a new crown. It's best to contact your dentist for a personalized cost estimate.
How Long Does it Take to Recover From a Root Canal on a Crowned Tooth?
Recovery time is generally short. You might experience some mild discomfort or sensitivity for a few days, but this usually subsides with over-the-counter pain relievers. Full recovery and placement of the permanent crown typically takes a couple of weeks.
