How to Read a Dental Treatment Plan and Estimate

You finish a dental exam, and someone at the front desk hands you a printout with tooth numbers, codes, fees, an “insurance estimate” and a “patient portion.” It can feel like a bill in a foreign language, and it may arrive just when you are trying to absorb news about a cavity or a crown. This guide walks you through a typical dental treatment plan line by line, explains the most common terms, and gives you a list of questions to ask before you agree to anything.

How this guide differs: this article explains how to read the treatment plan document itself. For why prices for the same procedure differ from place to place, see how dental costs vary by city; for comparing quotes, see how to get a fair price on dental work.

Key takeaways

• A treatment plan lists each procedure, tooth, code and estimated cost.
• The patient portion is an estimate, not a final bill.
• Ask which items are urgent, what the alternatives are and whether work can be phased.
• You can take the plan home and get a second opinion.

Every office formats plans differently, so use this as a general map rather than a template.

What a treatment plan is

A treatment plan is your dentist’s written proposal for care: what they recommend, which teeth are involved, the order of the work and the expected cost. An estimate is a best guess, not a guarantee, especially for the insurance portion. You can take it home, ask questions, and get a second opinion before you decide.

The parts of a typical plan

Patient and insurance information

At the top you will usually see your name, the dentist, the date and your insurance plan. Check that the insurance is current. An outdated plan can make every estimate below it wrong.

Tooth number and surfaces

Most U.S. offices number adult teeth from 1 to 32, starting at the back of the upper right and ending at the back of the lower right. Surfaces are often abbreviated with letters, such as O for the chewing surface, M and D for the sides toward and away from the front of the mouth, B or F for the cheek or lip side, and L for the tongue side. So a filling noted as “MO” on a back tooth covers the chewing surface and the front-facing side. If any abbreviation is unclear, ask; our dental glossary can also help.

Procedure codes

Each line usually has a code that starts with the letter D followed by four digits. These are CDT codes. The American Dental Association explains that the Code on Dental Procedures and Nomenclature (the CDT Code) assures consistency in documenting dental treatment, and the ADA updates it each year through its Code Maintenance Committee (ADA: CDT Code). Insurers use the same codes to decide what they cover, which is why the code matters as much as the description.

Codes are grouped by type of service, such as exams and X-rays, preventive care, fillings, crowns, root canals, gum treatment, extractions, dentures and implants, and anesthesia or sedation. You do not need to memorize them. What matters is that each line has a clear plain-language description you understand.

Fee, insurance estimate and patient portion

• Fee is what the office charges for that procedure. If you are in-network, there may also be a lower contracted fee.
• Insurance estimate is what the office expects your plan to pay, based on your coverage percentage, deductible and remaining annual maximum.
• Patient portion is what you are expected to pay. This is the number to focus on, but remember it is an estimate.

Our dental insurance glossary explains terms like deductible, coinsurance, annual maximum, waiting period and frequency limit, and our guide to understanding dental insurance explains how they fit together.

Phases or priorities

Many plans are split into phases. A common order is: urgent care first (pain or infection), then disease control (cavities and gum disease), then restorations such as crowns, and finally elective or cosmetic work. Phasing can also help spread costs across insurance years.

Alternatives

Good plans sometimes list options side by side, such as a filling versus a crown, or a root canal and crown versus extraction. If yours only shows one option, ask whether there are alternatives and what happens if you wait.

Common line items, explained

• Exam and X-rays. The ADA notes that X-rays can reveal problems not visible during an exam, such as new cavities, and that X-rays should be taken only when your dentist believes they will provide necessary diagnostic information (ADA MouthHealthy: X-rays). If you recently had X-rays elsewhere, the ADA says your new dentist may be able to use copies.
• Fillings. Usually listed by tooth and number of surfaces. Our cavities guide explains why decay is treated.
• Scaling and root planing. Often listed by quadrant (a quarter of the mouth). See our article on deep cleaning for what this treatment involves.
• Crowns, buildups and root canals. A root canal on a back tooth is often followed by a buildup and a crown, which may appear as separate lines. Our crown guide and root canal guide explain each.
• Sedation. Nitrous oxide or deeper sedation is usually its own line. See our guide to dental sedation options.

Questions to ask before you say yes

1. What is the problem with each tooth, and can you show me on the X-ray or photo?
2. What happens if I wait, and which items are urgent?
3. Are there alternatives, and what are the pros, cons and costs of each?
4. Is this estimate based on my current insurance benefits? Has a pre-treatment estimate been sent to my insurer?
5. How much of my annual maximum is left, and would splitting the work across benefit years help?
6. Are there separate fees, such as lab fees, sedation or follow-up visits, that are not listed?
7. How long is this estimate valid, and what payment options do you offer?

Getting a second opinion

A second opinion is reasonable for large or expensive plans. Bring a copy of your X-rays and treatment plan so the second dentist does not have to repeat everything. NIDCR notes that it does not provide referrals or second opinions itself, and suggests your state or local dental organization for a list of dentists in your area (NIDCR: Finding Dental Care). You can also search our dentist directory.

If the total is more than you can pay

Ask the office which items are most urgent and whether they can be phased. Look into lower-cost options, including dental school clinics and our page on low-cost dental care. If you are on Medicare, read our article on Medicare dental coverage, since Original Medicare covers dental care only in limited situations.

A simple way to review your plan at home

1. Highlight anything marked urgent or tied to pain or infection.
2. Circle every term or abbreviation you do not understand and look it up or ask.
3. Add up the patient portion for each phase separately.
4. Call your insurer with the codes to confirm coverage and your remaining annual maximum.
5. Decide what to schedule now and what to plan for later, then call the office to book.

Frequently asked questions

Is the patient portion on my estimate final?

Usually not. It is an estimate. Your actual cost can change based on what your insurer pays, what the dentist finds during treatment and whether your benefits have changed.

What does the D code mean?

It is a CDT procedure code. The ADA maintains the CDT Code to keep the documentation of dental treatment consistent, and insurers use it to process claims.

Can I ask for a copy of my X-rays?

Yes, you can ask. The ADA notes that a new dentist may ask your previous dentist for copies instead of taking new X-rays.

Do I have to do everything on the plan at once?

No. Ask your dentist which items are urgent and which can safely wait, and plan the rest around your budget and benefits.
