A root canal is a procedure used to treat infection or inflammation inside a tooth. The treatment removes infected pulp, disinfects the canal, and seals the tooth to relieve pain and preserve natural structure whenever possible.
Severe tooth pain, lingering sensitivity, or swelling around a tooth may indicate infection inside the pulp. A root canal is a procedure designed to remove infection, relieve discomfort, and preserve the natural tooth when possible.

What Is a Root Canal?
A root canal is a dental procedure used to treat infection or inflammation inside the tooth. The inner pulp, which contains nerves and blood vessels, can become infected due to deep decay, cracks, trauma, or repeated dental procedures.
During a root canal, the dentist or specialist:
- Removes infected or damaged pulp
- Cleans and disinfects the canal system
- Seals the space to prevent reinfection
- Prepares the tooth for restoration
Preserving the natural tooth helps maintain bite balance and chewing function.
Signs You May Need a Root Canal
Common symptoms that may indicate the need for root canal treatment include:
- Persistent or throbbing tooth pain
- Sensitivity to hot or cold that lingers
- Swelling around the gums
- Tenderness when biting
- Darkening of a tooth
If pain is severe or sudden, seeking evaluation by an emergency dentist may be the first step before definitive treatment is completed.
Who Performs Root Canals?
Many general dentists perform routine root canal procedures. However, complex cases may be referred to an endodontist, a specialist trained in treating conditions inside the tooth.
Referral may be recommended when:
- Infection is extensive
- Root anatomy is complex
- Previous treatment has failed
- Symptoms are difficult to diagnose
Your provider will explain whether specialist involvement is appropriate.
What Happens During the Procedure?
Root canal treatment typically involves:
- Local anesthesia to numb the area
- Creating a small access opening in the tooth
- Removing infected pulp tissue
- Cleaning and shaping the canals
- Filling and sealing the canal space
Afterward, the tooth is often restored with a filling or crown to protect it from fracture.
Is a Root Canal Painful?
Modern root canal procedures are performed under local anesthesia. Many patients report that treatment feels similar to receiving a filling.
Discomfort following the procedure is typically mild and temporary. If dental anxiety is a concern, discussing comfort strategies in advance can help. In certain cases, options similar to those used in sedation dentistry may be considered.
What Happens If a Root Canal Is Delayed?
Untreated infection inside a tooth can worsen over time. Possible complications include:
- Increased pain
- Abscess formation
- Spread of infection
- Tooth loss
Prompt evaluation improves the likelihood of preserving the natural tooth.
If the tooth cannot be saved, replacement options such as dental implants or dentures may be discussed after healing.
Recovery After a Root Canal
After treatment, mild tenderness is common for a few days. Patients are usually advised to:
- Avoid chewing on the treated side temporarily
- Maintain proper oral hygiene
- Attend follow-up appointments
Routine preventive care, including professional teeth cleaning, supports long-term oral health and helps monitor treated teeth.
