Understanding Root Canal Therapy
A root canal is a restorative treatment designed to save a natural tooth affected by infection or deep decay. Inside every tooth lies a soft tissue called the pulp, which contains nerves and blood vessels essential to keeping the tooth alive.
When the pulp becomes infected or inflamed—often due to a deep cavity, fracture, or injury—it can cause severe pain, swelling, or sensitivity. Without treatment, the infection can spread, leading to more serious problems or even tooth loss. Root canal therapy removes the damaged pulp, disinfects the tooth’s interior, and seals it to prevent reinfection—restoring comfort and protecting your natural smile.
When is a Root Canal Needed?
A root canal is usually recommended when decay or damage reaches the inner pulp layer of a tooth. Ignoring these signs can worsen the infection and lead to more complex dental issues.
You may need a root canal if you experience:
- Persistent or throbbing tooth pain
- Sensitivity to heat or cold that lingers
- Pain when chewing or touching the tooth
- Gum swelling or tenderness near the affected tooth
- A tooth that darkens or changes color
If you notice these symptoms, it’s important to schedule a visit to Gentle Smiles of Raleigh right away for proper evaluation.
Who Needs Root Canal Therapy?
Your dentist will carefully examine your tooth, often using digital X-rays, to determine if the pulp is infected or damaged. If so, a root canal may be the best way to relieve pain and save the tooth.
This procedure is both safe and effective, helping preserve your natural tooth structure while eliminating discomfort and infection.
What to Expect During the Procedure
Root canal therapy is typically completed in one or two visits and begins with local anesthesia to ensure your comfort. A small protective cover called a dental dam is placed around the tooth to keep it clean and isolated.
The dentist then removes the infected tissue, thoroughly cleans and disinfects the inner chamber, and fills it with a special material to strengthen and protect the tooth. Finally, the opening is sealed with a filling.
In most cases, a dental crown is placed afterward to restore the tooth’s full strength, shape, and natural appearance. With proper care, a treated tooth can last for many years—sometimes even a lifetime.
