Root Canal Treatment FAQs
No - despite its reputation, a root canal is performed to relieve the pain caused by an infected tooth, not to cause it. The area is fully numbed before treatment, and most patients report feeling no more discomfort than they would during a filling.
A persistent, severe toothache that doesn't go away is one of the most common signs you may need a root canal, since it often indicates infection has reached the inner pulp of the tooth. Other signs include sensitivity to hot or cold that lingers, swelling, or a darkening tooth.
Root canal treatment is completed in two stages: first, the dentist removes the infected pulp from inside the tooth and cleans the area; then the tooth is restored, typically with a crown, to protect it going forward.
In most cases, yes - a root canal removes the infected tissue from inside the tooth, and a crown is placed afterward to protect what's left of the natural structure and restore full chewing function.
