The difference between an endodontist and a dentist comes down to training and case focus: an endodontist is a dentist who completed a residency in the pulp and root canal system, meeting CODA's minimum of 24 months of full-time study, while a general dentist handles the variety of dental needs BLS describes.
The two chairs meet on root canals: by the common pattern, a GP keeps straightforward cases and sends molars, retreatments, and complex anatomy to an endodontist, who typically refers the patient back once the root canal is done.
What's the difference between an endodontist and a dentist?
Every endodontist is a dentist first — the difference is what happens after dental school.
A general dentist handles a variety of dental needs — BLS counts most dentists as general practitioners; an endodontist is a dentist who narrowed to one part of the tooth after an additional residency.
Root canals are where the two chairs can overlap — a GP might keep straightforward cases, depending on training and comfort — but the training depth, the typical case difficulty, and how the patient arrives all differ.
Many general dentists do some root canals themselves and refer the rest.
An endodontist's cases usually arrive on referral from another dentist.
What each one does
A general dentist runs comprehensive primary oral care — exams, fillings, crowns, extractions, and preventive care are the core of it, the wide range of work BLS lists for dentists, from filling cavities to placing sealants — and root canal therapy can sit on that list too, case by case.
An endodontist does one thing in depth: diagnosing pulp and root problems, performing root canal therapy, retreating canals that didn't heal, and endodontic surgery — the non-surgical and surgical treatment and retreatment CODA's standards require training in.
| Comparison | General dentist | Endodontist |
|---|---|---|
| Root canal cases — the common divide | Routine, single canal, front teeth or premolars | Molars, retreatments, complex or unusual canal anatomy |
| Training beyond dental school | None after dental school (BLS) | CODA-accredited endodontics residency, 24-month minimum |
| Board certification | None (certification attaches to the specialties) | American Board of Endodontics (ABE) — voluntary |
| How the patient arrives | The dentist's own patient | On referral, typically |
| National median pay (BLS, May 2025) | $170,950 (SOC 29-1021) | $224,990 (all-other-specialists category, SOC 29-1029) |
What the endodontics residency adds
Both start the same way: a bachelor's degree, then dental school for a DDS or DMD, then licensure.
A general dentist can begin practicing there — a postdoctoral year is optional unless a state's licensure route requires one.
An endodontist continues into an accredited endodontics residency — CODA's published minimum is 24 months of full-time study — built around non-surgical and surgical endodontic treatment and retreatment, the standards' required training areas.
See what the residency requires for the full accreditation detail.
After residency, endodontists can pursue certification from the American Board of Endodontics (ABE), the specialty's NCRDSCB-recognized certifying board — voluntary, not required to practice.
The residency adds what the general dentist's training doesn't cover in the same depth; the dental school and the license came first for both.
See becoming a board-certified endodontist for how ABE certification itself works.
Which root canal cases a GP keeps
None of the sources this page cites quantifies the split, so read the divide below as the training line the specialty draws, not a case-mix statistic.
There's no fixed rule — the line moves with each dentist's training and comfort — but a common pattern holds.
General dentists tend to keep straightforward, single-canal cases on front teeth and premolars, where the anatomy is predictable and access is easy.
What tends to get referred: molars with multiple curved canals, retreatment of a root canal that failed or is reinfected, teeth with unusual or calcified canal anatomy, cracked-tooth cases where the diagnosis itself is difficult, and any case where the referring dentist judges the tooth worth specialist care.
The referral relationship runs both ways
The cases that reach an endodontist usually arrive on referral from a general dentist — the referral is how the divide in the section above works in practice.
And the relationship doesn't end when the canal is filled: an endodontist typically completes the root canal itself and then refers the patient back to the referring general dentist for the crown or other final restoration and for ongoing care.
A general dentist can refer outward to other specialties too — an oral surgeon or an orthodontist among them — but this handoff typically runs both ways.
The case in and the patient back is what makes the referral relationship between these two roles distinctive.
Endodontist vs. dentist salary
On the published benchmarks, specialist-side pay sits higher — with caveats about what each figure measures.
The U.S. Bureau of Labor Statistics tracks general dentists on their own occupational code: SOC 29-1021, Dentists, General, with a national median of $170,950 a year (OEWS, May 2025).
Endodontics has no dedicated code — BLS groups endodontists into "Dentists, all other specialists" (SOC 29-1029), a catch-all category whose national median was $224,990 a year in the same release.
That category combines several specialties BLS doesn't report separately, so it is a grouped benchmark rather than an endodontist wage.
The distributions overlap, too: the 75th-percentile general dentist wage was $224,040 — close to the $224,990 all-other-specialists median (both OEWS, May 2025).
And OEWS wage estimates leave out the self-employed and owners and partners in unincorporated firms, which matters in a specialty where ADA HPI counted 26.9% of endodontists practicing solo in 2024.
ADA HPI's Survey of Dental Practice is the nearest named-source anchor, and it points the same direction.
Its latest published median net income for private-practice endodontists is $279,040, for 2021 — HPI has suppressed the endodontist figures every year since, so this isn't a same-year comparison.
In the same survey's 2025 data, median net income was $199,140 for GP owners and $165,520 for employed GPs; the endodontist figure combines owners and employees.
Net income (after practice expenses) is also a different measure from the OEWS wage series.
| Pay benchmark | General dentist | Endodontist |
|---|---|---|
| BLS median wage (OEWS, May 2025) | $170,950 (SOC 29-1021) | $224,990 (SOC 29-1029, all-other-specialists category) |
| ADA HPI median net income, private practice | $199,140 owners · $165,520 employed (2025) | $279,040 (2021, latest published — owners and employees combined) |
