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. 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.
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.
We discuss whether a crown is needed after treatment at your very first visit, not as a surprise afterward. We schedule the crown appointment before you even leave your root canal visit.
Every root canal case is a little different depending on which tooth and how advanced the infection is.
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.
An apex locator helps confirm exact canal length, reducing the chance of under- or over-treatment. 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.
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.
"Put off calling for weeks because I dreaded a root canal. It was genuinely nothing like what I feared."
"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."
Lingering pain to hot or cold, especially if it wakes you at night, often points to nerve involvement that a filling can't 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. 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. Skipping a needed crown risks the tooth fracturing later, which we explain clearly.
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. We verify insurance benefits before treatment so you know your out-of-pocket cost.
