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.
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. 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. 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. 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.
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.
Call +1-866-227-2801 and describe the pain — lingering sensitivity, swelling, or throbbing all point us toward the right exam.
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.
"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."
"They checked my numbness twice before starting. Appreciated that they didn't rush it."
"Pain was gone within a day of treatment. Wish I hadn't waited so long to call."
"Pulp testing before treatment confirmed exactly what was going on. No guessing involved."
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.
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.
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.
Our team serves Keene and the surrounding zip codes with digital imaging on-site at every location. Whether it's your first root canal or a retreatment case, our Keene team handles both in-house.
We'll confirm what's actually happening before recommending treatment.
