A root canal is a procedure designed to treat the infected pulp of a tooth. The pulp, located within the tooth's inner chamber, contains nerves and blood vessels. Infection can occur due to deep cavities, cracks, or trauma. But what happens when this infection strikes a tooth that's already crowned? This article will comprehensively explore root canals on crowned teeth, answering common questions and clarifying any misconceptions.
What Happens During a Root Canal on a Crowned Tooth?
The process of a root canal on a crowned tooth is largely similar to a root canal on a natural tooth, though with a few key differences. The dentist will first need to access the infected pulp chamber. Since the tooth is already crowned, they'll carefully remove a portion of the crown to expose the tooth structure beneath. This often involves using a small diamond bur to create an access opening.
Once access is gained, the infected pulp is removed, the canals are cleaned and shaped, and a medicated filling material is placed to seal the canals and prevent reinfection. After the root canal is completed, the dentist will then have several options for restoring the tooth:
- Recrowning: The existing crown may be re-cemented, or a new, more durable crown might be necessary.
- Filling: If the damage is minimal after the root canal, the tooth might be restored with a filling instead of a crown. This is less common but possible.
How Long Does a Root Canal on a Crowned Tooth Take?
The duration of a root canal on a crowned tooth can vary. While the root canal procedure itself might take a similar amount of time as one on a natural tooth (typically 1-2 hours), the additional steps of removing and replacing (or creating a new) crown significantly add to the overall time. You should expect the entire process to take longer, potentially requiring multiple appointments.
Does a Crowned Tooth Need a Root Canal More Often?
While a crown protects the tooth structure from further decay and fracture, it doesn't prevent infection of the tooth’s pulp. A crowned tooth can still develop an infection, necessitating a root canal. In fact, a crack or fracture developing under the crown might go unnoticed until infection occurs, making early detection challenging. This doesn't mean crowned teeth need root canals more often, but they are still susceptible to the same issues that can lead to the need for a root canal.
Is a Root Canal on a Crowned Tooth More Expensive?
Yes, a root canal on a crowned tooth is typically more expensive than a root canal on a natural tooth. This added cost reflects the extra work involved in removing and restoring the crown. The dentist may also consider additional factors during billing, such as the complexity of the procedure and the materials used.
Can I Avoid a Root Canal on a Crowned Tooth?
Unfortunately, if the pulp is severely infected, a root canal is often the only way to save the tooth. Ignoring the infection can lead to more significant problems, including the spread of infection, abscess formation, and ultimately, tooth extraction. While preventative care such as regular checkups and good oral hygiene are crucial, they cannot always prevent the need for a root canal.
What Are the Long-Term Outcomes of a Root Canal on a Crowned Tooth?
With proper aftercare and regular dental checkups, a successfully completed root canal on a crowned tooth can last for many years. The crown provides significant protection to the restored tooth, enhancing its longevity. However, maintaining good oral hygiene remains critical, and any future problems should be addressed promptly by a dentist.
How Much Does a Root Canal on a Crowned Tooth Cost?
The cost varies greatly depending on location, the dentist's fees, the complexity of the procedure, and the materials used. It's best to contact your dentist for a personalized quote. Factors like the need for additional imaging (X-rays) also impact the final price.
