Root canal treatment often has an undeserved reputation for being painful, but modern dentistry has made the procedure as comfortable as getting a regular filling. Understanding what happens during a root canal can help ease anxiety and prepare you for this important dental procedure.

What Is a Root Canal?

A root canal is a dental procedure designed to save a tooth that has become infected or severely damaged. The treatment involves removing the infected or inflamed pulp from inside the tooth, cleaning and disinfecting the inner chambers, and then filling and sealing the space.

The pulp is the soft tissue inside your tooth that contains nerves, blood vessels, and connective tissue. When it becomes infected due to deep decay, repeated dental procedures, or a crack in the tooth, a root canal becomes necessary to prevent the spread of infection and tooth loss.

Signs You Might Need a Root Canal

  • • Severe tooth pain that persists or worsens, especially when chewing or applying pressure
  • • Prolonged sensitivity to hot or cold temperatures that lingers after the stimulus is removed
  • • Tooth discoloration or darkening of the tooth
  • • Swollen or tender gums near the affected tooth
  • • A pimple or abscess on the gums

The Root Canal Procedure Step-by-Step

1. Diagnosis and X-rays

Your dentist will take X-rays to assess the extent of the infection and plan the treatment. Digital imaging helps visualize the shape of the root canals and determine if there are any signs of infection in the surrounding bone.

2. Anesthesia

Local anesthesia is administered to numb the affected tooth and surrounding area. Modern anesthetics are highly effective, ensuring you feel little to no discomfort during the procedure. Many patients report that the numbing injection is the only part they feel.

3. Accessing the Pulp

A protective rubber dam is placed around the tooth to keep it dry and prevent contamination. The dentist then creates a small opening in the crown of the tooth to access the pulp chamber and root canals.

4. Cleaning and Shaping

Using specialized instruments, the dentist carefully removes the infected or damaged pulp, bacteria, and debris from the pulp chamber and root canals. The canals are then shaped and cleaned with antibacterial solutions to eliminate any remaining infection.

5. Filling the Canals

Once cleaned and shaped, the canals are filled with a biocompatible material called gutta-percha. This rubber-like material is sealed in place with adhesive cement to prevent bacteria from re-entering the tooth.

6. Sealing and Restoration

A temporary filling is placed to close the opening. In most cases, a permanent crown will be needed to protect and restore the tooth to full function. Your dentist will schedule a follow-up appointment for crown placement, typically within a few weeks.

Recovery and Aftercare

After the procedure, it's normal to experience some sensitivity or mild discomfort for a few days. This can usually be managed with over-the-counter pain medication. Here are some tips for a smooth recovery:

  • • Avoid chewing on the treated tooth until the permanent restoration is in place
  • • Maintain good oral hygiene by brushing and flossing regularly
  • • Attend all follow-up appointments for crown placement
  • • Contact your dentist if you experience severe pain or swelling

Success Rate and Long-term Outlook

Root canal treatment has a high success rate of over 95%. With proper care and a crown to protect the tooth, a root canal-treated tooth can last a lifetime. Regular dental check-ups and good oral hygiene are essential to maintaining the health of your treated tooth.
