Whether it's a cracked tooth or deep decay reaching the pulp, Root Canal Treatment in St. Martins starts with imaging to confirm what's actually happening. 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. 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.
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. Same-week availability applies whether you're a longtime patient or calling us for the first time.
Post-treatment protection is part of the plan from day one, so the tooth stays saved long-term. 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.
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.
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.
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."
"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."
"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.
Modern anesthesia and technique make it far more comfortable than its reputation suggests — most patients report mild discomfort at most. Most patients tell us it was easier than they braced themselves for.
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.
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.
