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.

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.
Modern anesthesia techniques keep the procedure comfortable — most patients report less discomfort than expected. 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. Same-week availability applies whether you're a longtime patient or calling us for the first time.
We discuss whether a crown is needed after treatment at your very first visit, not as a surprise afterward. 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.
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.
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.
We check comfort throughout the procedure rather than assuming the anesthesia is holding.
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."
"Needed retreatment on an old root canal from another dentist years ago. They explained clearly why it had failed and what was different this time."
Lingering pain to hot or cold, especially if it wakes you at night, often points to nerve involvement that a filling can't fix. A filling addresses surface decay; a root canal addresses infection reaching the nerve — imaging tells us which applies.
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. An untreated infection can also spread beyond the tooth itself in more serious cases.
Cost depends on which tooth and whether a crown is needed — we give a specific quote after diagnosis, not a vague range. We verify insurance benefits before treatment so you know your out-of-pocket cost.
