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. 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. 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.
Here's what's typically involved once imaging confirms treatment is needed.
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.
We schedule crown placement as part of your treatment plan from the start, not as a separate afterthought. 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.
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."
"Pulp testing before treatment confirmed exactly what was going on. No guessing involved."
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.
Most cases are completed in one to two visits, depending on the tooth and infection severity. 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. 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.
