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.

We confirm nerve involvement with digital X-rays before recommending a root canal over a filling. 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. Comfort checks happen throughout, not just at the very start.
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.
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.
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.
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.
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.
"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."
"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."
We confirm with digital X-rays and sensitivity testing before recommending a root canal over a simpler 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. Multi-canal back teeth sometimes take longer than single-canal front teeth.
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.
