Orthodontics is one of the few things a family buys from a doctor on a payment plan, and the ads know it. "Braces for $99 a month." "No money down." "24 months to pay." For a parent staring at a $5,000 decision, a small monthly number is the most persuasive thing an orthodontic ad can say.
It's also the one most likely to break a federal rule without anyone noticing. The rule isn't about whether the offer is fair. It's about which words appear in the ad, and the words that feel most like financing aren't always the ones that trigger it. This bonus chapter walks through the line, what we found in real orthodontic ads, and how to say "affordable" with numbers without writing a legal problem into a 30-character headline.
A note before we start: this is our reading of the rules, not legal advice. A practice that advertises financing should have its ads and payment pages reviewed by its own counsel.
A Dollar Amount per Month Is a "Triggering Term" Under Federal Truth in Lending Rules.
The federal Truth in Lending Act is carried out by a regulation called Regulation Z, and one section of it, 12 CFR 1026.24, governs how credit is advertised. Regulation Z picks out four kinds of wording as "triggering terms." In an orthodontic ad they look like this:
- a down payment, in dollars or as a percentage ("$500 down," "10% to start")
- how many payments, or over how long ("24 payments," "two years to pay")
- what each payment is ("$99 a month")
- what the financing itself costs ("only $40 in finance charges")
Put one of those in a braces ad and three more items become mandatory: how much is due up front, how the balance is repaid, and the annual percentage rate by that name, even when it's 0%. The Consumer Financial Protection Bureau's official commentary gives examples of what counts. "$25 weekly" is a payment amount. "48-month payment terms" is a repayment period.
So "Braces for $99 a month" is a triggering term. So is "24 months to pay," and so is "$500 down." Each one, alone, means the ad has to carry the full set.
"No Money Down" and "Monthly Payment Plans" Don't Trigger the Disclosures on Their Own.
Here's the part that surprises people. Some of the most financing-sounding phrases aren't triggers at all.
The same commentary says that statements such as "no downpayment" do not trigger the additional disclosures. It says a phrase like "monthly payments to suit your needs" isn't a statement of a payment amount. And it says statements that there's no particular charge for credit aren't triggering terms either.
That gives an orthodontic ad a usable vocabulary. "Monthly payment plans." "No money down," as long as it's true. "Flexible payments." "No interest charged on in-house plans," if that's accurate. Each tells a parent that the cost can be spread out, without naming a figure that brings the full disclosure with it. The specific numbers can live where there's room to explain them.
A few example headlines that stay on the safe side of the line, each under 30 characters and each to be used only if accurate: "Monthly Payment Plans" (21), "No Money Down on Braces" (23), "0 Interest In-House Plans" (25), "Insurance and Payment Plans" (27). None names a payment amount, a number of payments or a down payment figure.
Notice the condition in that list: as long as it's true. A "No Money Down" ad that leads to a page requiring a minimum down payment isn't a Truth in Lending problem. It's a truth problem, the same mismatch Chapter 4 found between orthodontic ads and the pages behind them.
The Rule Reaches the Orthodontist Even When the Practice Isn't a Bank.
It's tempting to think these rules are for lenders. The commentary says otherwise: all persons must comply with the advertising provisions, not just creditors, and it names merchants specifically. A practice that advertises a payment plan is advertising credit, whether a third-party lender carries the balance or the practice does.
In-house plans deserve particular care. Regulation Z's definition of a creditor turns on credit payable by written agreement in more than four installments, and orthodontic payment contracts commonly run well past that, often with no interest. Our reading is that "Braces for $189 a month on our in-house plan" is a triggering term even at 0%, and the ad then needs the down payment, the repayment terms and an APR of 0% stated as an annual percentage rate.
Third-party financing counts too. Seven of the 12 practice sites we profiled name CareCredit, and one shows the card's purchase APR of 32.99% on its payment page. An ad that quotes a monthly figure for treatment paid through a lender is still advertising credit, and the rate behind it is exactly what the disclosure rule is meant to put in front of the patient.
None of that makes payment plans risky to offer. It makes them worth advertising carefully. A plan that's explained well is one of the strongest reasons a parent picks one practice over another.
13 Orthodontic Ads in Our Sample Mentioned Monthly Payments. Five Named a Dollar Amount, and None Stated an APR.
We read 162 orthodontic Search ads in our example market, Detroit, through Google's Ads Transparency Center. Thirteen of them, from five sites, mentioned monthly payments. Most used general phrases like "Affordable Monthly Payments" or "Flexible Monthly Payment Plans," the kind the commentary says don't trigger anything.
Five ads named a dollar amount per month. They came from two sites: one dental group advertising braces from $99 a month, and one mail-order aligner brand advertising $63 a month. Not one of the 13 stated an annual percentage rate. Nine ads, from four sites, mentioned a down payment in some form.
Patients notice when the terms are clear and when they aren't. In the Google reviews we read for Chapter 8, happy reviews praised practices for laying out "financial expectations" at the start and for giving families more than one way to pay. Among the 181 low-star orthodontic reviews, 12 complained about deposits, down payments, contracts or a written estimate the practice wouldn't give. A clear payment page isn't only compliance. It's the thing the next review will mention.
Five ads isn't a crisis, and we can't see what disclosures sat on the landing pages behind them. But the pattern is clear. The ads that named a monthly figure did it in a headline, where there's no room for anything else. That's exactly where the rule bites.
A 90-Character Ad Can't Carry the Full Disclosure, So the Dollar Figure Belongs on the Landing Page.
A Google Search ad gives you headlines of 30 characters and descriptions of 90. There's no practical way to fit "$99 a month, $500 down, 24 payments, 0% APR" into that space alongside anything that sells.
Regulation Z does offer electronic ads one route: the terms can sit in a table, if the triggering statement clearly refers to the page or location where the table begins. Whether a search ad's link to a landing page meets that standard isn't settled in the text, and we wouldn't bet a practice's compliance on it.
The safer pattern is simple. Keep the dollar figure out of the ad. Let the ad say "monthly payment plans" or "no money down" if it's true. Then put the specific figure on the landing page, together with everything it requires: the down payment, the number and frequency of payments, and the APR. A parent who clicks "monthly payment plans" lands on a page that says "As an example, $5,000 treatment: $500 down, 24 monthly payments of $187.50, 0% APR," with a short line about who qualifies.
Google's own ad policy points the same way. Under its policy on dishonest pricing, an advertiser has to make the payment structure and the total cost plain, interest included where there is any. A landing page that spells out the plan satisfies both.
Two more safeguards close the gaps. If the account uses AI Max or Performance Max, add the messaging restriction from Chapter 13 that stops Google from generating prices, because a generated headline can pull "$99/month" straight off the page you just wrote. And remember that pinned text can be dropped when final URL expansion picks a different page, so a disclosure belongs on every page an ad can land on, not only in the ad.
State Dental Boards Add Price Rules of Their Own, Starting With the Free Consultation.
Federal credit rules are only half of it. State dental boards set their own rules for prices and offers, and the free consultation, offered by all 12 practices we profiled, draws more of those rules than any other orthodontic offer we found. In the 10 states whose rules we checked:
- California requires price ads to be exact and bars phrases such as "as low as," "and up" and "lowest prices." A discount ad must list the fee before the discount.
- Texas requires a discount ad to state the standard fee, and bars implying a service is free or discounted when its fee is built into another procedure the patient pays for.
- Florida requires a set statement, in capital letters, in any ad for a free or discounted exam or treatment.
- Illinois lets a dentist advertise a free exam but bars charging the new patient for any service provided at that visit.
- Pennsylvania and Georgia require an advertised free service to stay free for 60 days after the last ad runs, unless the ad states a different period.
Search ads are short, and none of these states has guidance written for a 30-character headline. The practical answer is the same one as for financing: keep the ad's promise simple and true, and put the conditions on the page it links to, in the form your state requires.
An orthodontic practice that would rather have someone write its payment and offer ads with these rules in mind, and send its counsel the pages to review, can see what our Google Ads management includes.
Next: General Dentists Bid on Braces Searches Too. Chapter 15 Covers Who Can Say "Orthodontist."
Chapter 13 finished the rollout with AI Max. The next bonus chapter looks at the competitor most orthodontists underestimate, the general dentist who also sells braces, and the state rules on who gets to call themselves an orthodontist in an ad.
This chapter is part of Google Ads for Orthodontists, our sixteen-chapter guide for orthodontic practices anywhere in the US.
