Don’t let fear keep you from getting care—root canals today are safe, effective, and often the best way to avoid an extraction.
Signs You Might Need a Root Canal

- Pimple-like bump on the gums (may drain pus)
What Happens During an Emergency Root Canal
We’ll take X-rays to assess the tooth and numb the area fully for comfort. Then, we’ll carefully remove the infected pulp from inside the tooth, clean and seal the root canal system, and protect the tooth with a filling or temporary crown. You’ll receive detailed aftercare instructions and return later for a final crown if needed.
Our goal is to help you feel better fast while saving your tooth—and your smile.

Urgent Root Canal Therapy in Boston
A sudden toothache can strike at the worst possible moment. While sometimes it’s just sensitivity, a sharp, pulsing, or unbearable pain often indicates a deep infection of the tooth’s nerve. When swelling, pus, or fever appear, over-the-counter pain relievers won’t help. In these cases, an emergency root canal can save the tooth and stop the infection from spreading.
In Boston, fast access to care matters. At Emergency Dentist Boston, patients receive same-day evaluation, precise diagnosis, and urgent treatment when needed. Acting quickly prevents tooth loss and serious complications.
What a Root Canal Is and How It Works
Inside each tooth is the pulp—nerves and blood vessels that keep the tooth alive. Bacteria can reach this tissue through a cavity, crack, or trauma, causing inflammation or an abscess. Root canal therapy removes infected pulp, disinfects the canals, and seals them to protect the tooth.
Modern endodontics uses high-precision tools and digital imaging, making treatment safe and typically very comfortable with local anesthesia.
When an Emergency Root Canal Is Necessary
- Sharp, spontaneous tooth pain (often worse at night)
- Persistent pressure or sensitivity when chewing
- Redness, swelling, or a pus-filled bump (fistula) on the gum
- A “raised” feeling—as if the tooth sits higher than others
- Fever with facial or gum swelling
Cracks or chips can also allow bacteria in—even without immediate pain. If you notice these signs, seek urgent care at Emergency Dentist Boston.
Root Canal Pain, Cracked Teeth, and Related Issues
Why the pain happens: Bacterial infection inside the canals creates pressure in a confined space, compressing nerves and causing throbbing pain. Pus buildup or microfractures can worsen symptoms.
Root canal infection risks: Untreated infection may cause abscesses, bone loss, and—in rare cases—systemic spread. Thorough canal disinfection and careful follow-up at Emergency Dentist Boston reduce these risks.
Cracks after trauma or treatment: Pain on biting, sudden “zing,” or intermittent discomfort may indicate a crack. Early diagnostics (including 3D imaging) help save the tooth with bonding, a crown, or bite adjustment.
Recovery and Possible Short-Term Side Effects
Mild soreness or sensitivity for 1–3 days is common. You might notice brief pressure near the gums, slight chewing discomfort, or jaw fatigue after a long visit. A temporary filling can make the tooth feel “high”; if this lasts beyond a few days, a quick adjustment helps.
- Rinse gently with warm salt water
- Use a cold compress intermittently for swelling
- Avoid hard foods on the treated side for 24–48 hours
Contact the clinic promptly if you experience worsening pain, increasing swelling, or fever.
Alternatives—and Why Acting Fast Matters
Extraction is the main alternative when a tooth can’t be restored, but it can lead to shifting teeth, bite problems, bone loss, and the need for implants or bridges. When possible, saving your natural tooth with a root canal is the gold standard—it maintains chewing function, protects jawbone, and delivers excellent cosmetic results once restored with a crown.
Delays allow infection to spread and make treatment more complex. If you notice lingering pain, swelling, pus, or color change, contact Emergency Dentist Boston immediately.
Conclusion
An emergency root canal is often the quickest, safest way to end severe pain and save an infected tooth. With today’s anesthesia and technology at Emergency Dentist Boston, treatment is typically comfortable and recovery is quick. Don’t wait—early care protects your tooth, your health, and your peace of mind.
