A root canal has a reputation it doesn't deserve anymore — modern technique and anesthesia make it manageable. 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. Saving the natural tooth is almost always better than the alternative, so we treat this procedure with real care.
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.
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. 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.
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.
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.
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.
"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."
"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. 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. We schedule the crown visit separately once the canal treatment itself is complete.
Often yes, since the tooth becomes more brittle without its nerve supply — we discuss this at your first visit. We plan crown placement into your treatment timeline from day one.
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.
We break out the root canal and crown costs separately so you understand the full picture. Molars with multiple canals typically cost more than single-canal front teeth.
