A Guide to Root Canal Treatment
A root canal is a treatment designed to save a tooth that has become infected or damaged deep inside. Each tooth contains a soft center called the pulp, which has nerves and blood vessels that keep the tooth healthy.
When the pulp becomes infected—often due to a deep cavity, cracked tooth, or injury—it can cause pain, swelling, or sensitivity. If left untreated, the infection can spread and may result in tooth loss.
During a root canal, the infected pulp is removed, the inside of the tooth is thoroughly cleaned, and the tooth is sealed to prevent future problems. This treatment eases pain while preserving your natural tooth.
How to Know If a Root Canal Is Necessary
Most root canals are performed when tooth decay reaches the pulp, often due to an untreated cavity. A cracked or broken tooth can also expose the pulp, allowing bacteria to enter and cause infection.
You may need a root canal if you experience:
- Persistent 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
Who Is Eligible for Root Canal Treatment?
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 procedure is common, safe, and effective, helping restore comfort while preventing more serious dental problems.
What to Expect During a Root Canal
The root canal process begins with local anesthesia to keep you comfortable. A small barrier called a dental dam is placed around the tooth to keep it clean and dry.
Next, the decayed portion is removed to access the infected pulp. Using specialized tools, the dentist carefully cleans and disinfects the inside of the tooth. The space is then filled with a protective material and sealed with a filling.
In most cases, a crown is placed later to protect the tooth and restore its full strength and shape.
While root canals may sound intimidating, they are a safe, effective way to treat infection and preserve your natural tooth for years to come.
