Almost nobody reaches it
That figure comes from a 2024 analysis by the ADA Health Policy Institute, reported in ADA News. Another 3.3% of patients come within $100 of common maximums like $1,000 or $1,500. Round it off and about 93% of patients finish the year with benefits they never touched.
Meanwhile the annual maximum is one of the most common reasons treatment gets postponed in a dental office, and a lot of that postponement doesn't save the patient a dollar.
This post covers what the maximum actually limits, the arithmetic that decides whether splitting treatment across two years does anything, and where the number really does bind.
What does the annual maximum actually cap?
It caps what the plan pays in a benefit year. It doesn't cap what the patient needs, what you can diagnose, or what the patient can schedule.
That distinction gets lost constantly, because the number arrives in the same sentence as the treatment plan. A patient hears "$1,500 maximum" and treats it as a budget for their mouth. It isn't. It's the ceiling on one party's contribution.
The other thing worth knowing is that it isn't as uniform as most offices assume. According to NADP figures reported by ADA News, 32.8% of in-network annual maximums fall between $1,000 and $1,500, 48.2% fall between $1,500 and $2,500, and 17.2% are above $2,500 or have no maximum at all. Two-thirds of plans are above $1,500. If your team quotes $1,500 from memory, they're quoting the minority case.
Does splitting treatment across two years actually help?
Run the numbers before you assume it does. Often it changes nothing.
Here's the common version. A patient needs two crowns at $1,300 each, so $2,600 in treatment. The plan covers major services at 50% with a $1,500 annual maximum, and the patient hasn't used any benefits.
The plan's share of $2,600 at 50% is $1,300. That's under the $1,500 maximum. Both crowns fit inside one benefit year, the plan pays $1,300, and the patient pays $1,300 no matter how you sequence it.
Now do it the other way. Crown one in November, crown two in February. The plan pays $650 each time, so the plan still pays $1,300 total and the patient still pays $1,300. The only thing that changed is that a broken-down tooth waited three months.
The coinsurance is what limited this plan's payment, not the maximum. Splitting the case gained the patient nothing and cost them time.
When does the maximum actually bind?
When the plan's share of the treatment exceeds it. That's the whole test.
Same plan, but now the patient needs four crowns at $1,300 each, so $5,200. At 50%, the plan's share would be $2,600. The maximum stops it at $1,500, so $1,100 of otherwise payable benefit is unavailable this year.
That's a real case for sequencing, and here the conversation is worth having. Do two crowns now and two after January and the patient captures $1,300 this year and the rest next year, instead of losing $1,100 to the cap.
The rule your treatment coordinator needs is one line of arithmetic. Multiply the treatment by the coinsurance percentage, then compare that to the remaining maximum. If the plan's share is under the remaining benefit, sequencing saves nothing and you should schedule the care.
Why hasn't the maximum gone up?
It mostly hasn't, and the profession's own trade body has said so.
ADA News notes that while some plans now offer $2,000 or more, many still promote the long-standing $1,000 level that was established some 40 years ago. Costs of materials, labor, and technology have not stayed where they were in the 1980s.
In 2024 the ADA adopted policy stating it doesn't support annual or lifetime maximums in dental benefit programs at all, and it has urged plans to account for inflation when setting benefit levels. That's a position rather than a prediction, and nothing about it changes what your patient's plan does this year.
There's a wrinkle worth knowing about how the 3.4% figure gets used. The National Association of Dental Plans, which is the dental insurers' own trade association, has published that 95% of Americans with coverage never hit the annual benefit maximum in a year. They use it to argue that maximums don't restrict care. The same number can just as easily mean patients stop before they get there. Nobody has published data that settles which it is, so be careful quoting it in either direction.
What should the office actually do with the number?
Know it, use it for the arithmetic above, and stop leading with it.
A patient's remaining benefit belongs in the treatment conversation as a fact about money, not as a warning. "Your plan has $800 left toward this, so your portion is $500" gives the patient something to decide about. Language about approaching a maximum reads as a reason to wait, which we covered in three words your front desk should stop saying.
Patients who are out of network have a different version of this conversation, which we covered in out-of-network dental billing.
The other honest use is at year end. Patients with unscheduled diagnosed treatment and unused benefits are a real list, and reaching out to them in October and November is a service rather than a sales tactic. Our post on filling open chair time with treatment you already diagnosed covers how to build that list from your own records.
Do this with your unscheduled treatment list
Pull your unscheduled treatment report and add two columns for every patient: benefits remaining this year, and the plan's share of their pending treatment at their coinsurance rate.
Sort by the gap. Patients whose plan share is comfortably under their remaining benefit should be scheduled now, because waiting costs them nothing and gains them nothing. Patients whose plan share exceeds their remaining benefit are the only ones where a two-year conversation is honest, and those calls are worth making before December.
FAQs
What is a dental insurance annual maximum?
It's the most a dental plan will pay toward a patient's covered treatment in one benefit year. Anything beyond it is the patient's responsibility. It limits the plan's payment, not the treatment the patient is allowed to receive.
What is a typical dental annual maximum?
NADP figures reported by ADA News show 32.8% of in-network maximums between $1,000 and $1,500, 48.2% between $1,500 and $2,500, and 17.2% above $2,500 or uncapped. The often-quoted $1,500 is common but is not the majority case.
Should patients split dental treatment across two benefit years?
Only when the plan's share of the treatment exceeds the remaining annual maximum. Multiply the treatment fee by the coinsurance percentage and compare it to the benefit remaining. If the plan's share fits, splitting delays care without saving money.
Do unused dental benefits roll over?
Usually not. Most plans reset the maximum at the start of each benefit year and unused benefit is gone. Some plans offer carryover features, so check the individual plan rather than assuming.
How many people reach their dental annual maximum?
A 2024 ADA Health Policy Institute analysis found 3.4% of dental patients reach the typical annual maximum, and another 3.3% come within $100 of it.
