Few phrases make dental patients more nervous than “you need a root canal.” The reality is far gentler than the reputation: modern root canal therapy is a routine, comfortable procedure that relieves pain rather than causing it — and it’s usually the difference between keeping your natural tooth and losing it. Here’s what Arlington patients should know about the warning signs, the treatment itself, and what it costs at Madison Square Dental.
What a root canal actually does
Inside every tooth is a soft core of nerves and blood vessels called the pulp. When deep decay, a crack, or an injury lets bacteria reach the pulp, it becomes inflamed or infected — and because the pulp sits in a sealed space, the pressure and pain can be intense. A root canal removes the infected pulp, cleans and disinfects the canals inside the roots, and seals the tooth so bacteria can’t return. The tooth stays in your mouth, your bite stays intact, and the pain source is gone.
Warning signs you shouldn’t ignore
- Lingering pain with hot or cold — sensitivity that keeps aching for more than a few seconds after the temperature is gone.
- Spontaneous or nighttime toothache — pain that shows up without a trigger, or wakes you up.
- Pain when biting or chewing on one specific tooth.
- A pimple-like bump on the gums near the sore tooth, sometimes with a bad taste — a sign infection is draining.
- A darkening tooth — a gray or brown shift in one tooth can mean the pulp is dying.
- Swelling in the gums, face, or jaw around the tooth.
Not every one of these symptoms means a root canal — but every one of them deserves an exam. Infections don’t heal on their own, and waiting typically turns a straightforward root canal into an extraction.
What to expect during treatment
At Madison Square Dental, a root canal usually follows four simple steps:
- Diagnosis. An exam and x-rays confirm which tooth is involved and how far the infection extends.
- Numbing. The tooth and surrounding area are thoroughly anesthetized. For most patients, the procedure feels similar to getting a filling.
- Cleaning and sealing. The infected pulp is removed, the canals are cleaned, shaped, and disinfected, then filled and sealed with a rubber-like material.
- Restoring the tooth. A back tooth that has had a root canal usually needs a crown to protect it long term; a front tooth can sometimes be restored with a filling alone.
Most root canals are finished in a single visit, and most patients return to work or school the same day. Mild soreness for a day or two is normal and typically managed with over-the-counter pain relief.
What a root canal costs in Arlington
At Madison Square Dental, root canal treatment is $799 — transparent, flat pricing with no surprise bills. If the tooth needs a protective crown afterward, our zirconia crowns are $899. Many PPO dental plans cover a significant portion of endodontic treatment, and our front office verifies your benefits before treatment so you know your out-of-pocket cost up front. Financing options are available for patients who prefer to spread payments out.
Root canal vs. extraction: why saving the tooth usually wins
Pulling a painful tooth can look like the cheaper, faster fix — but the empty space rarely stays “free.” Neighboring teeth drift, chewing shifts to one side, and replacing the tooth later with a bridge or implant costs considerably more than the root canal would have. Keeping your natural tooth preserves your bite, your jawbone, and usually your budget. That said, some teeth are too damaged to save; when that’s the case, our doctors will tell you honestly and walk you through replacement options.
Frequently asked questions
Does a root canal hurt? The procedure itself is done under local anesthesia and feels much like a filling. What hurts is the infection beforehand — treatment is the relief.
How long does a root canal take? Typically 60–90 minutes, and most cases are completed in one visit.
How long does a treated tooth last? With a proper crown and good home care, a root-canal-treated tooth can last a lifetime.
Can I wait to treat it? Waiting lets the infection spread — into the bone, the neighboring teeth, or beyond. Earlier treatment is simpler, cheaper, and more comfortable.
