Understanding Root Canal Therapy
A root canal is a treatment that saves a tooth with infection or damage deep inside. The tooth’s pulp contains nerves and blood vessels essential for its health.
Infection from a cavity, crack, or injury can cause pain, swelling, or sensitivity and may lead to tooth loss if untreated.
Root canal therapy removes the infected pulp, cleans the tooth, and seals it, relieving pain while preserving your natural tooth.
When Do You Need a Root Canal?
Most root canals are needed when tooth decay reaches the pulp, often from an untreated cavity. A cracked or broken tooth can also expose the pulp, allowing bacteria to enter and cause infection.
You might need a root canal if you have:
- Ongoing or severe tooth pain
- Pain when chewing or touching the tooth
- Sensitivity to hot or cold that doesn’t go away
- Swelling or tenderness near the gums
- A tooth that has darkened in color
If you experience any of these symptoms, see your dentist promptly to prevent further damage.
Who Can Get a Root Canal?
To determine if a root canal is necessary, your dentist will examine your tooth and may take an X-ray. If the pulp is infected or exposed, a root canal is often the best way to relieve pain and preserve the tooth.
This common, safe treatment restores comfort and helps prevent more serious dental problems.
What Happens During the Procedure?
The root canal process begins with local anesthesia to keep you comfortable. A dental dam is placed around the tooth to keep it clean and dry.
The dentist removes the decayed portion to access the infected pulp, gently cleans and disinfects the inside of the tooth, and fills it with a protective material before sealing it with a filling.
In most cases, a crown is placed later to restore the tooth’s full strength and shape. While root canals may sound intimidating, they are a safe and effective way to treat infection and preserve your natural tooth for years.
