If you have a toothache that won't go away, extreme sensitivity to cold or heat, or swelling in the gum that comes and goes, you may need a root canal. It is one of the most common procedures in dentistry and, contrary to what many people believe, it is the most effective way to save a tooth that would otherwise have to be extracted.
What exactly is a root canal?
A root canal — also called root canal therapy or endodontic treatment — involves removing the dental pulp (the soft tissue inside the tooth) when it is inflamed or infected. The internal canals of the tooth are cleaned, disinfected, and sealed to prevent the infection from returning. The tooth stays in place and continues to function normally.
What are the signs that I need a root canal?
These are the most common signs that you may need root canal therapy:
- Intense and constant pain when chewing or when pressing on the tooth
- Prolonged sensitivity to cold or heat that does not go away after removing the stimulus
- Inflamed gums or an abscess (a small bump with pus near the tooth)
- Darkening of the tooth — a color change indicating pulp damage
- Pain that wakes you up at night or appears spontaneously
If you experience any of these symptoms, it is important to come in for an evaluation as soon as possible. The earlier it is treated, the better the results.
How does the procedure work?
Root canal therapy is generally completed in one or two visits and follows these steps:
- Diagnosis with digital radiography: The extent of the damage is evaluated and the treatment is planned.
- Local anesthesia: The area is fully numbed so you don't feel pain during the procedure.
- Access to the canal: A small opening is made in the crown of the tooth to reach the pulp.
- Cleaning and disinfection: Using precision rotary instruments and disinfecting solutions, the infected tissue is removed.
- Obturation: The canals are sealed with a biocompatible material.
- Final restoration: A crown or restoration is placed to protect the tooth long-term.
Does a root canal hurt?
With modern anesthesia and today's technology, a root canal does not hurt more than a regular filling. At Clínica Endodontics we use an operating microscope, rotary system, and electronic apex locator, which lets us work with greater precision, shorten procedure time, and improve your comfort during the appointment.
How long is recovery?
Most patients return to normal activities the next day. It is normal to feel mild sensitivity in the area for 2 to 3 days, easily managed with common pain relievers. If the tooth had a severe infection, recovery may take a few extra days.
Why is a root canal better than an extraction?
Whenever possible, keeping your natural tooth is the best option. A tooth treated with a root canal can last a lifetime with proper care. An extraction, on the other hand, requires replacing the tooth with an implant, bridge, or denture — more expensive and complex procedures. A root canal preserves your natural bite, your appearance, and the health of neighboring teeth.
