after the treatment
After your treatment, your tooth has to be restored to work and look like a natural tooth. This will include a crown or filling depending on the strength of the treated tooth.
A root canal treatment does not protect your tooth from other damage from occurring. You are still susceptible to a cavity or gum disease. With proper care, your treated tooth can last as long as your healthy teeth. Most of the time, a root canal treatment is successful the first time. In a rare case, a second treatment may be required. During a retreatment, the root canal filling is removed, recleaned, reshaped, and refilled.
