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. 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.
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.
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.
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.
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.
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.
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.
"They showed me the X-ray and explained exactly why a filling wouldn't be enough. Made the decision easy."
"Crown discussion happened at the first visit, not as a surprise bill after the root canal was already done."
"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.
Modern anesthesia and technique make it far more comfortable than its reputation suggests — most patients report mild discomfort at most. 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. 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. We'd rather treat it now while the tooth is still savable.
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.
