Denver's Leading Dentist for Gum Disease, Root Canals & Implants
Failed-Root-Canal
Failed Root Canal Cases
Every week, patients walk into Dr. Dana Ellis's Denver office carrying the same weight.
A root canal done two years ago — still hurting.
A tooth that swelled again six months after treatment.
An X-ray that shows nothing wrong — yet the pain never left.
A dentist who finally said the words nobody wants to hear:
"I think we need to extract it."
​
These are not rare cases. These are not unusual stories.
These are the cases that find Dr. Ellis — because nobody else knew what to do next.
What most patients don't realize is this — a failed root canal is almost never the patient's fault. It is anatomy. It is technology. It is the difference between a general dentist doing their best — and a specialist who has spent forty years mastering exactly this.
​
A single missed canal — one millimeter of untreated infection invisible to a standard X-ray — is all it takes. Bacteria survive. Infection rebuilds. Pain returns. And a tooth that should have been saved for life begins its countdown toward extraction.
​
​
Every saved tooth represents more than function. It’s a patient who keeps their own smile, their own bite, their confidence. It’s a mouth that stays stable for decades instead of entering the cycle of extractions and implants. LANAP has made that outcome achievable for people who once thought it was too late.
Do NOT Ignore Any More
Complex Cases
Forty years of root canal mastery means Dr. Ellis has seen anatomy that would stop most specialists cold.
​
The molar with six canals curving in four directions.
The calcified root canal sealed so tightly it took a specialist's instruments just to access.
The tooth with a broken file locked inside the canal from a previous procedure.
The patient whose infection had spread into the surrounding jawbone — silently, painlessly — for three years before anyone caught it.
The root canal done overseas that looked perfect on X-ray — yet harbored a missed canal feeding chronic inflammation straight into the bloodstream.
​
These are not textbook cases.
These are the cases that separate a dentist from a master.
Dr. Ellis approaches every complex root canal the same way — with 3D cone beam imaging that maps every millimeter of your root anatomy before a single instrument touches your tooth. With microscope magnification that reveals what no standard X-ray ever could. With forty years of pattern recognition that tells her exactly where the missed canal hides — before she even begins.
Patients fly from Tokyo. From London. From Sydney. From across the United States.
Not because Denver is close.
Because Dr. Ellis is the answer they stopped believing existed.
