About DentalCode

DentalCode is an independent reference that explains dental procedure codes in plain English. Every line on a dental estimate is one of these codes, and almost nothing published about them is written for the person holding the bill. That is the gap this site exists to fill.

What each page is for

There are three kinds of page here, and the split is deliberate.

Code pages — one for each code, at its own address, such as /d2740. A code page is about the code: what conditions the number carries, where its fee sits relative to the codes around it, how a payer is likely to treat it, and — the part that causes most of the trouble — how it differs from each of the similar-sounding codes it gets substituted for.

Treatment guides — one for each procedure, such as dental crowns or root canal treatment. These cover the dentistry rather than the billing: what the appointments involve, the alternatives worth weighing, how long the result lasts, and what actually drives the price.

Category pages — one for each of the twelve ranges, such as restorative. Each explains how that part of the code set is organised, what the money and benefit rules look like across it, and what goes wrong on claims in that section specifically.

Where the fee ranges come from

The ranges on this site are typical private fees in the United States before insurance, drawn from published fee surveys, dental plan schedules and reported practice fees, then sanity-checked against each other. They are ranges rather than prices for a reason: the same crown differs by more than half between a metropolitan and a rural practice, and no national figure can tell you what your own dentist charges.

Treat them as a way to recognise a quote that is far outside the normal band, not as a quotation. The only number that binds anyone is the one your practice gives you in writing, and the only number that tells you your own share is a pre-treatment estimate from your insurer.

How the writing is done

Every explanation here is written in our own words from clinical and benefit knowledge. Where the evidence on a question is genuinely mixed — prophylactic wisdom tooth removal, amalgam safety, whether a particular graft works in a particular defect — we say so rather than picking the tidier answer.

We do not reproduce the official code descriptors. Code numbers are facts and are freely usable; the descriptor wording is the American Dental Association's copyrighted work, and none of it is quoted on this site.

What this site is not

It is not dental advice, and it is not a billing service. It cannot tell you whether a particular treatment is right for you, and it cannot tell you what your plan will pay. It can tell you what to ask, which is usually the more useful thing at the point where you are reading an estimate and wondering whether to sign it.
