Your dentist hands you a referral slip, says you need a root canal, and sends you to someone called an endodontist. For most people, that’s the first time they’ve heard the word, and it raises a fair question: what exactly is an endodontist, and why can’t my regular dentist just handle this? The short answer is that an endodontist is a dental specialist who has completed two to three years of advanced training beyond dental school, focused entirely on the inside of your teeth.
At West Atlanta Endodontics, that distinction matters in every appointment. Dr. David Norrington and Dr. James Smithson II have each completed formal endodontic residency programs, and their entire practice is devoted to one specialty. Before diving into our endodontic procedures, here’s what sets an endodontist apart and why it matters for your care.
What an Endodontist Actually Does
An endodontist’s entire focus is the dental pulp, the soft tissue inside your tooth that contains nerves, blood vessels, and connective tissue. When that pulp becomes infected or inflamed, it causes the kind of tooth pain that is hard to ignore. Endodontists are trained to diagnose where that pain is coming from, treat the source, and save the tooth whenever possible.
The procedures an endodontist handles are more complex than routine dental care. While root canal therapy accounts for the vast majority of cases, endodontists also treat cracked teeth, dental trauma, and perform surgical procedures like apicoectomies when a standard root canal is not sufficient. These are cases that require both specialized training and a level of precision that comes from performing these procedures repeatedly.
How the Training Is Different
A general dentist completes four years of dental school and is equipped to handle a wide range of oral health needs, from cleanings and fillings to extractions and crowns. An endodontist does all of that first, then goes back for an additional two to three years of advanced residency training focused exclusively on diagnosing tooth pain and treating the interior of teeth.
According to the American Association of Endodontists, fewer than three percent of dentists are endodontists. That narrow specialization means endodontists perform these procedures at a far greater volume and depth of focus than a general dentist who handles many types of cases throughout the day. The result is a level of precision that comes specifically from doing one thing very well.
Why Patients Are Referred to an Endodontist
Most patients arrive at an endodontist’s office through a referral from their general dentist. That referral typically happens when the tooth’s condition is complex enough to benefit from a specialist, when the root canal anatomy is difficult, or when previous treatment has not resolved the problem. In some cases, patients come directly after experiencing tooth pain or dental trauma.
The reasons a general dentist refers a case include the following considerations, and any one of them may apply to your situation:
- Complex root anatomy: Teeth with multiple canals or unusual curvature require specialist tools and precision.
- Persistent infection: When prior treatment has not healed the tooth or the infection has spread.
- Dental trauma: Injuries from accidents that affect the pulp or root, even without visible damage.
- Diagnostic uncertainty: When the source of tooth pain is difficult to pinpoint without advanced imaging.
Each of these scenarios benefits from the focused training and technology an endodontist brings to the table, including cone beam CT imaging that produces three-dimensional views of the tooth and surrounding bone.
What Makes an Endodontist’s Approach Different in Practice
The difference between a general dentist and an endodontist is not just a matter of credentials. It shows up in how the appointment is structured, what equipment is used, and how complex cases are handled. Dr. Norrington spent nine years as a mechanical engineer before dental school, and that analytical, precision-focused perspective informs how he approaches each case. Dr. Smithson conducted clinical research on injection techniques during his residency at Ohio State, with a focus on improving anesthetic efficacy for patients who have difficulty getting numb.
Both doctors use operating microscopes, cone beam CT imaging, ultrasonic irrigation, and Ion Plus biocompatible sealer. They also limit their daily caseload to a select number of root canals per day, well below what in-network offices typically schedule, so that no patient feels rushed and every case gets the attention it deserves.
