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.
We check numbness thoroughly before starting, not just assume the injection worked. 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. We know how miserable this pain can be, which is why we don't make you wait unnecessarily.
We discuss whether a crown is needed after treatment at your very first visit, not as a surprise afterward. 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.
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.
The canal is cleaned, shaped, and filled under local anesthesia, typically in one to two visits.
We schedule the follow-up before you leave, so nothing falls through the cracks.
"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."
"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. A filling addresses surface decay; a root canal addresses infection reaching the nerve — imaging tells us which applies.
We check numbness thoroughly before starting, so pain during the procedure is rare. Post-procedure soreness is normal for a few days and manageable with standard pain relief.
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. 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.
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.
