Why is root canal therapy necessary?
Inside the tooth is a small chamber where dental pulp and nerve endings live. This chamber is called a root canal. In a healthy tooth, the root canal is not susceptible to oral bacteria because the chamber is sealed. However, if a tooth is fractured or severely decayed, the root canal becomes exposed to bacteria. When exposed to bacteria, the root canal can become infected and since nerve endings are involved, an infection in this location can produce substantial discomfort and sensitivity. To remedy this discomfort and prevent further destruction to the inside of the tooth, root canal treatment is performed.
When is a crown needed?
A crown is a tooth-shaped restoration. When a tooth is damaged by extensive decay, cracked, or broken, it will need to be repaired so that it can provide a proper biting surface for chewing food and support neighboring teeth. To achieve these objectives, crown is placed over the tooth to protect it from more damage and restore the function of the tooth. Crowns are made for each individual patient based on very precise measurements.
What materials can I choose from for my crown?
Crowns can be made from different materials. For teeth that are more visible, white crowns made of all porcelain or porcelain fused to metal are the most natural looking options. Metal alloys may also be used for molars or for patients on a budget.
