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.

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. 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.
Post-treatment protection is part of the plan from day one, so the tooth stays saved long-term. 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.
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.
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."
"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.
We tell you which applies to your case after imaging, not as a generic estimate. 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. 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. Molars with multiple canals typically cost more than single-canal front teeth.
