D3310 — Endodontic therapy, anterior tooth (excluding final restoration)
Root canal treatment removes the pulp — the nerve and blood supply. D3310 is the version for a front tooth.
It is one of three codes covering root canal treatment. For the procedure itself rather than the code, see the root canal treatment guide; for the code, read on.
What the code requires, what it costs, how it is paid, and how to tell it from its neighbours — each in its own section below.
Reading D3310
Tooth — a front tooth — thinner enamel, a single root, and a result that is judged cosmetically rather than just functionally.
How D3310 differs from its neighbours
D3320 — Endodontic therapy, premolar tooth (excluding final restoration): It applies to premolars rather than front tooths.
D3330 — Endodontic therapy, molar tooth (excluding final restoration): It applies to molars rather than front tooths.
Those two codes and D3310 are the whole group — nothing else describes this procedure. Two of these codes on one estimate is not necessarily an error, but it is always worth asking what each line is for.

These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.

Questions about D3310
D3310 — what is it?
It is the entry for endodontic therapy, anterior tooth, excluding final restoration. A practice cannot use it for anything broader than that, which is what makes the code useful to you.
What is the typical fee for D3310?
$700–$1,400 is the realistic range before benefits. Your own share depends on your plan's percentage, deductible and remaining annual maximum.
Does dental insurance cover D3310?
In most cases yes, at the basic / major rate: typically 50–80%. The annual maximum is what usually decides how much of that you actually see.
What is the difference between D3310 and D3320?
D3320 is endodontic therapy, premolar tooth, excluding final restoration: it applies to premolars rather than front tooths. The rest of the procedure is the same, which is why the two get substituted for one another on estimates.
