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.

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.
We discuss whether a crown is needed after treatment at your very first visit, not as a surprise afterward. 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.
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.
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.
"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.
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. 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.
Our team serves Pennington Gap and the surrounding zip codes with digital imaging on-site at every location. We coordinate with local oral surgeons for retreatment cases that need it, so you're not searching for a referral yourself.
We'll confirm what's actually happening before recommending treatment.
