When is a Root Canal Needed?
Root canal therapy is usually necessary when decay or injury reaches the inner pulp of a tooth. Common signs you might need this treatment include:
- Persistent or severe tooth pain
- Discomfort when biting or chewing
- Prolonged sensitivity to hot or cold
- Swelling or tenderness around the gums
- A tooth that has darkened or changed color
If you experience any of these symptoms, it’s important to see your dentist promptly to prevent further damage or infection.
Who is a Candidate for a Root Canal?
During your exam, your dentist will check the affected tooth and may take digital X-rays to assess the extent of the infection. If the pulp is infected or exposed, a root canal is typically the best way to eliminate pain while preserving your natural tooth.
Root canal therapy is a safe, routine procedure performed under local anesthesia, ensuring maximum comfort and excellent long-term results.
What Happens During the Procedure?
Comfort First
To begin, the area around your tooth is gently numbed using a local anesthetic to ensure you feel completely comfortable and pain-free throughout the procedure. Most patients experience only mild pressure, not pain.
Isolation
Next, a small protective barrier called a dental dam is carefully placed around the affected tooth. This keeps the area clean, dry, and free from saliva during treatment, ensuring precision and safety.
Cleaning and Disinfection
Your dentist then removes the infected or damaged pulp from inside the tooth using specialized instruments. The inner canals are thoroughly cleaned, shaped, and disinfected to eliminate bacteria and prevent future infection.
Sealing and Restoration
Once the canals are cleaned, they’re filled with a durable, biocompatible material that seals the space completely. This step helps strengthen the tooth’s structure and prevents bacteria from entering again.
Final Protection
In most cases, a custom dental crown is placed over the treated tooth to restore its full strength, function, and appearance. This final step ensures lasting protection and a natural-looking smile.
