A Closer Look at Root Canal Therapy
A root canal is a restorative procedure designed to save a tooth that’s infected or severely damaged inside. Each tooth contains a soft tissue called the pulp, made up of nerves and blood vessels that nourish the tooth. When this pulp becomes infected—often due to deep decay, cracks, or trauma—it can cause pain, swelling, and sensitivity. If left untreated, the infection may spread and lead to tooth loss. A root canal removes the infected pulp, disinfects the inner tooth, and seals it to prevent future infection—relieving pain and preserving your natural tooth.
When is a Root Canal Needed?
Root canals are typically recommended when decay or injury reaches the pulp layer of the tooth. Ignoring cavities or cracks can allow bacteria to enter and cause infection. You may need a root canal if you experience:
- Severe or lingering tooth pain
- Pain when biting or touching the tooth
- Prolonged sensitivity to heat or cold
- Gum swelling or tenderness near one tooth
- Darkening or discoloration of a tooth
If any of these symptoms sound familiar, it’s important to visit your dentist promptly for evaluation and relief.
Who Can Benefit From Root Canal Therapy?
Your dentist will determine if a root canal is necessary through an exam and dental X-rays. If the pulp is infected or exposed, root canal therapy is often the best solution to stop the infection and save the tooth. This routine, highly effective treatment helps protect your oral health, relieve discomfort, and prevent more serious issues later on.
Step-by-step: The Root Canal Procedure
The procedure begins with local anesthesia to ensure complete comfort. A small dental dam is placed around the tooth to keep the area clean and dry. The dentist then removes decay and accesses the infected pulp. Using specialized instruments, the inside of the tooth is cleaned, disinfected, and filled with a durable, protective material. Finally, the tooth is sealed with a filling, and in most cases, a dental crown is added later to restore full strength and function.
Though often misunderstood, root canals are a safe, painless, and effective way to eliminate infection while preserving your natural smile.
