Understanding the Root Canal Procedure
A root canal is a dental procedure designed to save a tooth that has become infected or damaged deep within. Inside every tooth is a soft tissue called the pulp, which contains nerves and blood vessels that keep the tooth healthy.
When the pulp becomes infected—often due to a deep cavity, crack, or injury—it can cause pain, swelling, and sensitivity. If untreated, the infection may spread and could result in tooth loss. During a root canal, the infected pulp is removed, the inside of the tooth is thoroughly cleaned, and the space is sealed to prevent future infection. This treatment relieves pain and preserves your natural tooth.
When Root Canal Treatment Becomes Necessary
Most root canals are needed when tooth decay reaches the pulp—the soft inner tissue of the tooth. This can occur when a cavity is left untreated for too long. 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 lingers
- Swelling or tenderness around the gums
- A tooth that has darkened or changed color
If you notice any of these symptoms, it’s important to see your dentist as soon as possible to prevent the infection from spreading.
Who Is a Candidate for a Root Canal
To determine whether a root canal is needed, your dentist will examine your tooth and may take an X-ray to check for infection or damage. If the pulp is infected or exposed, a root canal is often the most effective way to relieve pain and preserve your natural tooth.
This procedure is safe, routine, and highly successful—it restores comfort, prevents further damage, and helps you maintain a healthy smile.
What Happens During Root Canal Treatment
The root canal procedure begins with numbing the area using local anesthesia to ensure your comfort. A small barrier, called a dental dam, is then placed around the tooth to keep it clean and dry during treatment.
Next, the dentist removes the decayed portion of the tooth to access the infected pulp. Using specialized instruments, the pulp is carefully cleaned out, and the inside of the tooth is disinfected. The cleaned space is then filled with a protective material and sealed with a filling.
In most cases, a dental crown is placed afterward to strengthen the tooth and restore its natural shape and function.
Although root canals may seem intimidating, they are a safe, effective treatment that eliminates infection, relieves pain, and helps preserve your natural tooth for years to come.
