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.
An apex locator helps measure canal length precisely during treatment, reducing guesswork. 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.
Every root canal case is a little different depending on which tooth and how advanced the infection is.
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.
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.
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.
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.
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."
"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."
We confirm with digital X-rays and sensitivity testing before recommending a root canal over a simpler fix. We won't recommend the more involved procedure unless testing actually confirms it's needed.
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. We schedule the crown visit separately once the canal treatment itself is complete.
Front teeth sometimes don't need a crown; back teeth that handle more chewing force usually do. 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.
Our team serves Leominster and the surrounding zip codes with digital imaging on-site at every location. We coordinate with local oral surgeons for retreatment cases that need it, so you're not searching for a referral yourself.
We'll confirm what's actually happening before recommending treatment.
