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.

We use imaging to confirm the diagnosis before recommending treatment, not just responding to reported pain. We'd rather take an extra ten minutes with the apex locator than leave canal length to a guess.

An apex locator helps measure canal length precisely during treatment, reducing guesswork. You'll see your own X-ray and understand the reasoning before we proceed.
Modern anesthesia techniques keep the procedure comfortable — most patients report less discomfort than expected. If you're still feeling anything, we pause and address it before continuing.
Severe pain gets triaged quickly — we don't make patients wait weeks for a diagnosed infection. 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.
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.
If a previously treated tooth becomes reinfected, we assess whether retreatment or extraction is the better path. We explain honestly whether your specific tooth is still a good save candidate.
We triage by phone to determine how quickly you need to be seen.
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.
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.
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.
Most cases are completed in one to two visits, depending on the tooth and infection severity. Multi-canal back teeth sometimes take longer than single-canal front teeth.
Front teeth sometimes don't need a crown; back teeth that handle more chewing force usually do. Skipping a needed crown risks the tooth fracturing later, which we explain clearly.
The infection can spread, cause worsening pain and swelling, and eventually require extraction instead of a save. We'd rather treat it now while the tooth is still savable.
Cost depends on which tooth and whether a crown is needed — we give a specific quote after diagnosis, not a vague range. Molars with multiple canals typically cost more than single-canal front teeth.
