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.

We confirm nerve involvement with digital X-rays before recommending a root canal over a filling. We'd rather over-image than under-treat a tooth that could still be saved.
Modern anesthesia techniques keep the procedure comfortable — most patients report less discomfort than expected. 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. 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.
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.
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.
A properly sealed canal is what keeps bacteria from returning to the treated tooth. We confirm the seal with a follow-up X-ray before moving to restoration.
Not every root canal needs this step — we explain when your specific tooth requires it. 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.
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.
The canal is cleaned, shaped, and filled under local anesthesia, typically in one to two visits.
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."
"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. We won't recommend the more involved procedure unless testing actually confirms it's needed.
Modern anesthesia and technique make it far more comfortable than its reputation suggests — most patients report mild discomfort at most. 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. We plan crown placement into your treatment timeline from day one.
Delaying rarely makes the problem go away — it typically makes treatment more complicated later. 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. We verify insurance benefits before treatment so you know your out-of-pocket cost.
