I often get asked by patients why a tooth that has undergone root canal therapy needs to be crowned. Given that a crown is a significant investment and the root canal itself can be costly, this question is entirely understandable.
The reason behind the recommendation is simple: without a crown, a root-treated tooth is highly susceptible to fracture. If the tooth fractures, it can lead to pain and potentially render the tooth unrestorable.
Here’s Why:
1. Compromised Tooth Structure: Typically, a tooth needing a root canal has been extensively damaged by decay or deep fillings. This leaves the remaining tooth structure weaker than that of a healthy tooth.
2. Loss of Vitality: After a root canal, the tooth loses its blood supply and nerve sensation. As a result, it becomes dehydrated, loses its elasticity, and becomes more brittle.
3. Reduced Sensitivity: With the loss of nerve function, you lose the natural reflex that helps protect your tooth from damage. If you bite down on something hard, you might not realize it until it’s too late, increasing the risk of cracks or fractures.
To prevent these issues, it’s crucial to restore the tooth properly after a root canal.
Here’s the process we follow:
1. Thorough Cleaning: We start by removing all excess gutta-percha, old fillings, and any residual decay from the cavity.
2. Reinforced Core: Next, we build up the core of the tooth with a strong resin material, reinforced by fiber and fiber posts.
3. Crowning: Finally, the reinforced core is sculpted to support a ceramic crown. This crown restores the tooth’s shape, shade, and size, while providing protection against cracks and fractures.
By placing a crown, we ensure that your root-treated tooth remains functional and durable for years to come. If you have any more questions or concerns about your dental treatments, feel free to ask during your next visit!
