Dr. Brad Isom and his team perform root canals regularly, combining modern technology with a calm, unhurried chairside manner to save your natural tooth and ease your worries.

Our Restorative & Surgical Dentistry team will explain every step in plain language before we begin.
What Is Root Canal Therapy?
A root canal is a procedure that removes infected or inflamed tissue from inside a tooth, called the pulp. Once that tissue is cleaned out, Dr. Isom disinfects the space, fills it, and seals the tooth to stop the infection from coming back. Many patients picture root canals as painful, but the procedure itself is designed to relieve pain, not cause it. The infection is what hurts. Treating it early is what brings relief.
Signs You May Need a Root Canal
Tooth pain doesn't always mean you need a root canal, but a few signs are worth paying attention to. You might need one if you notice:
- Sharp pain when you bite or chew
- Sensitivity to hot or cold that lingers well after the trigger is gone
- Swelling or tenderness in the gums near a specific tooth
- A tooth that has darkened or discolored
- A small bump on the gum that looks like a pimple
If any of these sound familiar, it's worth having Dr. Isom take a look before the problem gets bigger.
Benefits of Saving Your Natural Tooth
Whenever possible, keeping your own tooth is usually the better long-term choice. Root canal therapy lets you keep your natural bite, chewing strength, and smile, without the extra steps needed to replace a missing tooth. It also helps protect the surrounding teeth from shifting out of place, which can happen after an extraction. For most patients, saving the natural tooth is more comfortable, more affordable over time, and easier on the jawbone than removing it.
What to Expect During Your Root Canal Visit
Most root canals take one to two visits, depending on the tooth and the amount of infection. Dr. Isom starts by numbing the area completely, then removes the infected pulp, cleans the inside of the tooth, and seals it. Many patients need a crown afterward to protect the tooth and restore its strength. When that's the case, our Same-Day CEREC Crowns technology often means you can leave with a durable, natural-looking crown in a single appointment, instead of waiting weeks for a lab-made one.
Comfort-Focused Care for Anxious Patients
If dental anxiety has kept you from getting treatment, you're not alone, and you won't be rushed or judged here. Nitrous oxide is available for patients who want extra help relaxing, and Dr. Isom takes time to explain what's happening at each step. Our whole team is used to working with nervous patients, and we build in the time needed so you never feel hurried.
Root Canal or Extraction? Comparing Your Options
When a tooth is infected or badly damaged, you generally have two paths forward: save it with a root canal, or remove it with a tooth extraction. Both are valid options, and Dr. Isom will walk you through the pros and cons for your specific tooth before recommending one.
Root Canal vs. Tooth Extraction
| Feature | Root Canal Therapy | Tooth Extraction |
|---|---|---|
| Main goal | Saves and restores your natural tooth | Removes the damaged tooth entirely |
| Typical visits | One to two appointments | Usually one appointment |
| Recovery | Mild soreness for a few days | Soreness and socket healing time |
| Effect on smile | Keeps your original tooth and bite | Leaves a gap unless replaced |
| Follow-up treatment | Often finished with a crown | May need a dental implant or bridge later |
| Long-term cost | Often lower than extraction plus replacement | May cost less upfront, but a replacement tooth adds to the total |
For most patients, a root canal is the more conservative choice because it keeps your natural tooth in place. Extraction becomes the better option when a tooth is too damaged, cracked, or infected to be saved. Dr. Isom will always give you an honest recommendation based on what's best for your mouth, not a one-size-fits-all answer.

Does a root canal hurt? ⌄
Modern root canals are designed to feel similar to getting a filling. The area is fully numbed before treatment starts, and the procedure itself relieves the pain caused by the infection rather than adding to it. Most patients report mild soreness for a day or two afterward, which usually responds well to over-the-counter pain relievers.
What happens if an infected tooth goes untreated? ⌄
Left untreated, an infection inside the tooth can spread to the surrounding bone and tissue, leading to more pain, swelling, and a higher chance the tooth can't be saved. It won't go away on its own, even if the pain fades for a while. Getting it checked early usually means simpler, more comfortable treatment.
Will insurance cover my root canal? ⌄
Isom Dentistry accepts a wide range of PPO insurance plans, and root canal therapy is commonly covered, at least in part, under most dental plans. Coverage amounts vary by plan and provider, so our team is happy to help you understand your benefits before treatment. Visit our Insurance & Financing page for more details, or give us a call.
