Root Canal Therapy Without the Fear
If there's one dental procedure with an undeserved reputation, it's the root canal. For decades, root canal therapy has been shorthand for something painful and dreaded, but the truth is, modern root canal treatment is no more uncomfortable than getting a filling. In fact, for most patients, it's the infection causing their pain, not the procedure that relieves it. At W. Eric Martin, DDS, PC in Champaign, IL, root canal therapy is a routine, comfortable procedure that saves your natural tooth, eliminates pain, and stops infection in its tracks.

What Is Root Canal Therapy and Why Might You Need It?
Inside every tooth, beneath the hard enamel and the layer of dentin, is a soft inner chamber called the pulp. The pulp contains nerves, blood vessels, and connective tissue that help the tooth grow and develop. When bacteria from decay or a crack reach the pulp, the tissue becomes infected and inflamed, causing the pain, sensitivity, and swelling that signal something is seriously wrong.
Root canal therapy removes the infected pulp, cleans and disinfects the interior of the tooth, and seals it to prevent reinfection. The tooth is then typically restored with a crown to protect it and restore full function. The result: no more pain, no more infection, and most importantly, your natural tooth preserved.
Saving a natural tooth is almost always preferable to extraction. Your natural teeth are stronger, more functional, and better for your long-term oral health than any replacement option. Root canal therapy makes that possible.
Your Root Canal Treatment, Step by Step
Examination & X-Rays
We take digital X-rays to assess the extent of the infection and the condition of the surrounding bone. This gives us a complete picture of what we're dealing with before treatment begins.
Local Anesthetic
We administer a local anesthetic to completely numb the tooth and surrounding area. Most patients are surprised by how comfortable the procedure is once the anesthetic takes effect.
Isolate the Tooth
A small rubber dam is placed around the tooth to keep the area clean and dry throughout the procedure.
Access the Pulp
We create a small opening in the top of the tooth to access the infected pulp chamber and root canals beneath.
Remove the Infected Pulp
Using precise dental instruments, we carefully remove all infected and inflamed pulp tissue from the pulp chamber and each root canal.
Clean & Shape
The interior of the tooth is thoroughly cleaned, disinfected, and shaped to prepare it for the filling material.
Fill & Seal
The cleaned canals are filled with a biocompatible material called gutta-percha and sealed to prevent bacteria from re-entering.
Restore the Tooth
In most cases, a tooth that has undergone root canal therapy is restored with a crown to protect the remaining structure and restore full chewing function. We'll discuss your restoration options and next steps before you leave.
Signs You May Need Root Canal Therapy
Not every infected tooth causes dramatic symptoms, but when they appear, they shouldn't be ignored. Common signs that you may need root canal treatment include:
- Severe, persistent toothache, especially when chewing or applying pressure
- Prolonged sensitivity to heat or cold that lingers after the source is removed
- Darkening or discoloration of the tooth
- Swelling or tenderness in the nearby gum tissue
- A persistent pimple-like bump on the gums near the affected tooth
- A tooth that has been cracked, chipped, or subjected to repeated dental procedures
If you're experiencing any of these symptoms, call us as soon as possible. A tooth that needs a root canal won't get better on its own, and the sooner we treat it, the better your outcome will be.
In Pain? Don't Wait, We Can Help

We'll evaluate your situation promptly and get you out of pain as quickly as possible. Root canal therapy might just be the best appointment you've ever had.

Frequently Asked Questions About Root Canal Therapy
Is root canal therapy painful?
No — and this is the most important myth to bust. Root canal therapy is performed under local anesthetic, so the tooth and surrounding area are completely numb throughout the procedure. Most patients describe the experience as no more uncomfortable than a routine filling. The pain people associate with root canals is the infection itself — and the procedure is what ends it.
How do I know if I need a root canal or just a filling?
A filling treats surface-level decay that hasn't reached the inner pulp of the tooth. A root canal is needed when decay or damage has allowed bacteria to infect the pulp. Signs that the infection has reached the pulp include severe or persistent pain, prolonged sensitivity to temperature, swelling, or a visible pimple on the gum near the tooth. We'll assess the situation with an exam and X-rays and give you a clear diagnosis.
How long does root canal therapy take?
Most root canal procedures are completed in one to two appointments, each lasting between 60 and 90 minutes depending on the complexity of the tooth and the extent of the infection. Molars, which have more canals, may take longer than front teeth. We'll give you a clear timeline before we begin.
What happens after a root canal?
Some mild soreness in the area for a few days after treatment is normal and can usually be managed with over-the-counter pain relievers. Most patients return to normal activity the following day. You'll also need to return for a crown to protect and restore the treated tooth — we'll schedule that appointment before you leave.
Do I need a crown after a root canal?
In most cases, yes. A tooth that has undergone root canal therapy has had its pulp removed, which can make it more brittle over time. A crown protects the remaining tooth structure, restores its strength, and allows you to chew normally without risk of fracture. We'll discuss your restoration plan as part of your treatment.
Can a tooth get reinfected after a root canal?
In rare cases, a root canal can fail if bacteria re-enter the tooth — usually due to a delayed crown placement, a new cavity, or a crack. If this happens, the tooth may need to be retreated or referred to a specialist. This is why placing your crown promptly and maintaining good oral hygiene are so important after treatment.
What happens if I don't get a root canal when I need one?
The infection will not go away on its own. Left untreated, the bacteria can spread beyond the tooth into the surrounding bone and tissue, leading to a dental abscess, significant pain, and potential systemic health risks. Ultimately, the tooth may become unsalvageable and require extraction. Treating the infection early with root canal therapy is always the better outcome.
Can I drive myself home after a root canal?
If you've had standard local anesthetic only, yes — you can drive yourself home. If you've chosen sedation dentistry to help with anxiety, you'll need someone to drive you. We'll confirm this with you when you schedule your appointment.
