Understanding Root Canal Therapy
A root canal is a dental procedure designed to treat infection or inflammation deep inside a tooth. Each tooth contains a soft inner layer known as the pulp, which holds nerves and blood vessels that nourish the tooth. When this pulp becomes infected—often due to decay, a deep cavity, or a cracked tooth—it can lead to persistent pain, swelling, or sensitivity. Without timely treatment, the infection can worsen and even result in tooth loss.
A root canal gently removes the infected pulp, disinfects the area, and seals the tooth to prevent reinfection—helping you keep your natural tooth and eliminate discomfort.
When is a Root Canal Needed?
A root canal is usually recommended when the pulp becomes infected or damaged. This can occur from untreated cavities, cracks, or trauma that allows bacteria to enter the tooth.
You may need a root canal if you experience:
- Ongoing or severe toothache
- Sensitivity to hot or cold that lingers
- Pain while chewing or touching the tooth
- Swelling or tenderness around the gums
- A tooth that appears darker in color
If any of these symptoms sound familiar, it’s best to schedule an appointment with Johns Creek Dental Studio for an evaluation before the issue worsens.
Who Can Benefit From a Root Canal?
Your dentist will determine if a root canal is necessary through a clinical exam and X-rays. If the pulp shows signs of infection or exposure, this procedure is often the best solution to relieve pain and save the tooth.
Root canal therapy is both safe and routine, offering an effective way to restore your oral health while preventing more serious dental problems.
What to Expect During the Procedure
During a root canal, the affected area is numbed using local anesthesia to ensure your comfort. A small dental dam is placed to keep the tooth isolated and clean.
The dentist then removes the decayed or infected pulp, thoroughly cleans the root canals, and fills them with a protective material. Finally, the tooth is sealed with a filling.
In most cases, a custom crown is later placed over the treated tooth to strengthen it and restore its natural look and function.
Though often misunderstood, modern root canals are comfortable, safe, and highly effective at preserving your natural smile.
