A root canal has a reputation it doesn't deserve anymore — modern technique and anesthesia make it manageable. 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. We'd rather take an extra ten minutes with the apex locator than leave canal length to a guess.

We confirm nerve involvement with digital X-rays before recommending a root canal over a filling. We'd rather over-image than under-treat a tooth that could still be saved.
We check numbness thoroughly before starting, not just assume the injection worked. If you're still feeling anything, we pause and address it before continuing.
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.
We rule out a simple filling before recommending the more involved root canal procedure. 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.
A properly sealed canal is what keeps bacteria from returning to the treated tooth. We confirm the seal with a follow-up X-ray before moving to restoration.
For teeth with significant structure loss, a post-and-core buildup provides a foundation for the final crown. 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.
Digital X-rays and sensitivity testing confirm whether the nerve is involved and treatment is needed.
The canal is cleaned, shaped, and filled under local anesthesia, typically in one to two visits.
A crown or filling restores the tooth's strength, with a follow-up to confirm healing.
"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.
We check numbness thoroughly before starting, so pain during the procedure is rare. Most patients tell us it was easier than they braced themselves for.
Most cases are completed in one to two visits, depending on the tooth and infection severity. We schedule the crown visit separately once the canal treatment itself is complete.
Front teeth sometimes don't need a crown; back teeth that handle more chewing force usually do. We plan crown placement into your treatment timeline from day one.
The infection can spread, cause worsening pain and swelling, and eventually require extraction instead of a save. An untreated infection can also spread beyond the tooth itself in more serious cases.
We break out the root canal and crown costs separately so you understand the full picture. We verify insurance benefits before treatment so you know your out-of-pocket cost.
