Everything You Need to Know About Root Canals
A root canal is a procedure designed to save a tooth that’s infected or damaged deep inside. At the center of every tooth is the pulp, a soft tissue containing nerves and blood vessels that keep the tooth healthy.
When the pulp becomes infected—often due to a deep cavity, a cracked tooth, or injury—it can cause pain, swelling, or sensitivity. If left untreated, the infection can spread, potentially resulting in tooth loss. Root canal therapy removes the infected pulp, thoroughly cleans the inside of the tooth, and seals it to prevent future issues. This treatment relieves pain while preserving your natural tooth.
Identifying the Need for a Root Canal
Root canals are typically needed when tooth decay reaches the pulp, the soft tissue at the center of the tooth. This usually occurs 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 intense tooth pain
- Discomfort when biting or touching the tooth
- Prolonged sensitivity to hot or cold
- Swelling or tenderness around the gums
- Tooth darkening or discoloration
If you experience any of these signs, schedule a dental visit promptly.
Understanding Who Can Benefit From 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 most effective way to relieve pain and preserve the tooth.
This procedure is safe, common, and helps restore your comfort while preventing more serious dental problems.
What to Expect During a Root Canal
The root canal procedure begins with local anesthesia to ensure your comfort. A dental dam is placed around the tooth to keep it clean and dry.
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 restore the tooth’s strength, shape, and function.
While the idea of a root canal may seem intimidating, it’s a safe and highly effective way to treat infection and preserve your natural tooth for years to come.
