Understanding Root Canals: Saving Your Natural Tooth
A root canal is a procedure designed to save a tooth that has become infected or damaged deep inside. At the center of each tooth is the pulp—a soft tissue containing nerves and blood vessels essential for keeping the tooth healthy.
When the pulp becomes infected, often due to a deep cavity, a cracked tooth, or trauma, it can lead to pain, swelling, and sensitivity. If left untreated, the infection may spread and result in tooth loss. During a root canal, the infected pulp is removed, the interior of the tooth is thoroughly cleaned, and then sealed to prevent further issues. This treatment relieves pain and helps preserve your natural tooth.
When Do You Need a Root Canal?
Root canals are typically necessary when tooth decay reaches the pulp—the soft tissue inside the tooth. This usually occurs if 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 intense tooth pain
- Discomfort when chewing or touching the tooth
- Sensitivity to hot or cold that lingers
- Swelling or tenderness around the gums
- A tooth that has darkened in color
If you notice any of these signs, it’s important to see your dentist promptly to prevent further damage.
Who Can Get a Root Canal?
To determine if you need a root canal, your dentist will examine your tooth and may take an X-ray. If the pulp is infected or exposed, a root canal is usually the best option to relieve pain and save the tooth.
This procedure is routine, safe, and highly effective. It helps restore your comfort and prevents more serious dental problems down the road.
What Happens During the Procedure?
The root canal procedure begins with local anesthesia to numb the area and ensure your comfort. A small barrier called a dental dam is placed around the tooth to keep it clean and dry throughout the treatment.
The dentist then removes the decayed portion to access the infected pulp. Using specialized tools, the pulp is carefully cleaned out and the inside of the tooth is disinfected. The space is then filled with a protective material and sealed with a filling.
In most cases, a crown is placed afterward to protect the tooth and restore its full strength and appearance.
While root canals may seem daunting, they are a safe and effective way to treat infection and preserve your natural tooth for years to come.
