Persistent throbbing or sensitivity to hot and cold that lingers often means the nerve inside the tooth is infected or inflamed. Smile Center Dentistry uses digital X-rays and, when needed, an apex locator to treat the canal precisely.

A root canal performed with the right tools and enough time has a high success rate — rushed cases are where problems happen. Saving the natural tooth is almost always better than the alternative, so we treat this procedure with real care.

We confirm nerve involvement with digital X-rays before recommending a root canal over a filling. You'll see your own X-ray and understand the reasoning before we proceed.
We check numbness thoroughly before starting, not just assume the injection worked. Comfort checks happen throughout, not just at the very start.
Infected or badly decayed teeth don't wait well, so we prioritize root canal cases for same-week scheduling. We know how miserable this pain can be, which is why we don't make you wait unnecessarily.
Post-treatment protection is part of the plan from day one, so the tooth stays saved long-term. Skipping a needed crown is one of the most common reasons a treated tooth fails later.
Here's what's typically involved once imaging confirms treatment is needed.
Digital X-rays and cold/heat sensitivity testing confirm whether the nerve is infected or just inflamed. This step alone often explains pain patients couldn't previously identify.
Infected pulp tissue is removed and the canal is cleaned and shaped to prepare it for filling. This is the core of the procedure and where precision matters most.
The cleaned canal is filled with a biocompatible material and sealed to prevent reinfection. We confirm the seal with a follow-up X-ray before moving to restoration.
Not every root canal needs this step — we explain when your specific tooth requires it. This step is planned before crown placement, not decided last minute.
A crown protects a root-canal-treated tooth from fracture, since it's more brittle without its nerve supply. Material options are discussed based on which tooth and how much force it takes when chewing.
Retreatment involves reopening the tooth, cleaning it again, and resealing — more involved than the original procedure. We explain honestly whether your specific tooth is still a good save candidate.
Call +1-866-227-2801 and describe the pain — lingering sensitivity, swelling, or throbbing all point us toward the right exam.
You'll see your own X-ray and understand exactly what's happening before we recommend anything.
The canal is cleaned, shaped, and filled under local anesthesia, typically in one to two visits.
We schedule the follow-up before you leave, so nothing falls through the cracks.
"They showed me the X-ray and explained exactly why a filling wouldn't be enough. Made the decision easy."
"Got in the same week I called with severe pain. Anesthesia worked well and I felt nothing during the procedure."
"Two visits total — cleaning and shaping first, crown fitted a couple weeks later. Tooth feels completely normal now."
"Follow-up X-ray confirmed everything sealed properly. Nice to have that confirmation instead of just hoping."
"Pulp testing before treatment confirmed exactly what was going on. No guessing involved."
We confirm with digital X-rays and sensitivity testing before recommending a root canal over a simpler fix. We won't recommend the more involved procedure unless testing actually confirms it's needed.
Modern anesthesia and technique make it far more comfortable than its reputation suggests — most patients report mild discomfort at most. Most patients tell us it was easier than they braced themselves for.
We tell you which applies to your case after imaging, not as a generic estimate. Multi-canal back teeth sometimes take longer than single-canal front teeth.
Often yes, since the tooth becomes more brittle without its nerve supply — we discuss this at your first visit. We plan crown placement into your treatment timeline from day one.
Delaying rarely makes the problem go away — it typically makes treatment more complicated later. We'd rather treat it now while the tooth is still savable.
We break out the root canal and crown costs separately so you understand the full picture. Molars with multiple canals typically cost more than single-canal front teeth.
Our team serves Louisville and the surrounding zip codes with digital imaging on-site at every location. Whether it's your first root canal or a retreatment case, our Louisville team handles both in-house.
We'll confirm what's actually happening before recommending treatment.
