Root Canal Therapy to Save Infected Teeth
Root canal therapy is a restorative dental procedure designed to treat infection inside a tooth. When bacteria reach the pulp—the inner tissue containing nerves and blood vessels—it can cause severe pain, swelling, and potential tooth loss if untreated. For patients in Whittier, root canal therapy helps eliminate infection while preserving the natural tooth structure.
What happens during a root canal?
The goal of root canal treatment is to remove infected tissue from inside the tooth and seal the canals to prevent reinfection. Once completed, the tooth can often function normally again with the help of a protective restoration.
- Removal of infected pulp The damaged tissue inside the tooth is carefully removed to eliminate bacteria.
- Cleaning and disinfecting the canals The internal canals are thoroughly cleaned to remove remaining infection.
- Sealing the tooth The cleaned canals are filled with a biocompatible material to prevent reinfection.
- Restoration with a crown In many cases, a crown is placed afterward to restore strength and durability.
Signs you may need root canal therapy
Infections within the tooth often cause noticeable symptoms. If any of the following signs occur, a dental evaluation may be necessary to determine whether root canal treatment is needed.
- Persistent or severe tooth pain
- Long-lasting sensitivity to hot or cold
- Swelling or tenderness in the gums
- Darkening or discoloration of a tooth
- A pimple-like bump on the gums near the affected tooth
The root canal treatment process
Root canal therapy is typically completed in one or two visits depending on the complexity of the infection. Modern techniques and anesthesia help make the procedure comfortable for most patients.
- Local anesthesia The treatment area is numbed to ensure comfort during the procedure.
- Access to the pulp chamber A small opening is created in the tooth to reach the infected tissue.
- Cleaning and shaping The canals are cleaned and prepared for sealing.
- Sealing and restoration The tooth is sealed and often restored with a crown to strengthen it.
Benefits of root canal therapy
