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. We'd rather over-image than under-treat a tooth that could still be saved.
Modern anesthesia techniques keep the procedure comfortable — most patients report less discomfort than expected. Comfort checks happen throughout, not just at the very start.
Severe pain gets triaged quickly — we don't make patients wait weeks for a diagnosed infection. Same-week availability applies whether you're a longtime patient or calling us for the first time.
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.
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.
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.
We schedule crown placement as part of your treatment plan from the start, not as a separate afterthought. 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.
Digital X-rays and sensitivity testing confirm whether the nerve is involved and treatment is needed.
We check comfort throughout the procedure rather than assuming the anesthesia is holding.
A crown or filling restores the tooth's strength, with a follow-up to confirm healing.
"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."
"They checked my numbness twice before starting. Appreciated that they didn't rush it."
"Pain was gone within a day of treatment. Wish I hadn't waited so long to call."
"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.
Modern anesthesia and technique make it far more comfortable than its reputation suggests — most patients report mild discomfort at most. Post-procedure soreness is normal for a few days and manageable with standard pain relief.
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.
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.
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.
