Root canals have a reputation for being the worst thing that can happen in a dental chair. That reputation is decades out of date. Modern root canal treatment is routine, performed under anesthetic, and for most patients no more uncomfortable than getting a filling.
What actually makes a root canal necessary is an infection inside the tooth. That infection causes real discomfort. The treatment relieves it.
Key Takeaways
- A root canal removes infected tissue from inside the tooth so the tooth can be saved.
- The infection itself causes the significant discomfort. The treatment relieves it.
- Modern root canal treatment is generally no more uncomfortable than getting a filling.
- A crown is placed on the tooth after treatment to protect it from fracture.
- Leaving an infected tooth untreated leads to spreading infection, bone loss, and eventual tooth loss.
- Dr. J.C. Chang handles root canal treatment at Image Dental. No outside referral needed.
Why a Root Canal Is Needed
Inside every tooth, beneath the hard enamel and dentin, is a soft tissue called the pulp. The pulp contains nerves and blood vessels. In a healthy tooth, it stays protected. When bacteria reach it, through deep decay, a crack, or a broken restoration, the pulp becomes infected.
The body can’t clear this type of infection on its own. Unlike an infected cut or a sore throat, the inside of a tooth has no way for the immune system to access the problem. The infection grows. It spreads toward the tip of the root and into the surrounding bone.
Root canal therapy removes the infected tissue, cleans the canals, and seals them so the tooth can be saved. Without treatment, the infection continues until the tooth is lost entirely and the bone around it is compromised.
Signs You Might Need a Root Canal
These are the most common indicators:
- Severe toothache that worsens when lying down or bending forward
- Prolonged sensitivity to heat or cold that lingers after the stimulus is removed
- A tooth that has darkened compared to the teeth around it
- Swelling or tenderness in the gum near a specific tooth
- A small pimple-like bump on the gum near the tooth, which may drain and disappear, then return
Some infected teeth have no symptoms at all. The infection develops silently and shows up on an X-ray before the patient feels anything. That’s one reason regular checkups catch problems that waiting at home doesn’t.
Does a Root Canal Hurt?
A root canal is performed under local anesthetic. Most patients feel pressure during the procedure but not pain. The tooth and surrounding area are numb before treatment begins. Many patients report the recovery afterward is milder than expected. The infection before treatment is almost always more uncomfortable than the procedure itself.
What most patients describe during treatment is pressure, the sensation of instruments working in the tooth, and vibration from certain tools. Not pain. The area is thoroughly numb.
Post-procedure discomfort is real. The tooth and surrounding gum may be tender for a few days. Over-the-counter ibuprofen as directed handles most of it. Most patients return to normal activity the same day or the next day.
What Happens During a Root Canal?
The dentist numbs the tooth and places a rubber dam to isolate the area. A small opening is made through the crown to access the pulp chamber. The infected tissue is removed, the canals are cleaned and shaped, and the space is filled and sealed. Most cases are completed in one to two appointments.
The steps in sequence:
- Local anesthetic administered until the area is fully numb
- Rubber dam placed to keep the area dry and isolated
- Small access opening made through the crown of the tooth
- Infected pulp removed from the pulp chamber and root canals
- Canals cleaned, shaped, and disinfected
- Canals filled with gutta-percha, a rubber-like sealing material
- Tooth sealed; crown placement scheduled

Root Canal vs Tooth Extraction
Some patients ask whether it’s better to skip the root canal and just remove the tooth. Here’s the honest comparison:
| Option | Saves the tooth | Bone preserved | Follow-up needed |
| Root canal + crown | Yes | Yes | Crown placement 2-4 weeks later |
| Extraction | No | Bone loss begins immediately | Replacement tooth (bridge or implant) recommended |
Extraction is sometimes the right call, especially when a tooth is too damaged to restore or when the full treatment isn’t financially feasible. But saving the tooth when it’s possible is almost always better long-term. Replacing a missing tooth costs more than saving it, and bone loss in the extraction site affects the surrounding teeth over time.
Root Canal Recovery
Most patients feel tender around the treated tooth for two to three days. Chewing on that side is uncomfortable until the permanent crown is placed. That’s by design. The tooth is fragile without a crown. A crack before the crown is placed can mean the tooth can’t be saved.
Plan for the crown appointment two to four weeks after the root canal. Between now and then, stick to the other side of your mouth for anything hard or chewy.
