Use It or Lose It: Year-End Dental Benefits
Most dental plans run on the calendar year. Whatever is left of your annual maximum disappears on December 31, and your deductible starts over in January. If you have treatment you have been putting off, or you are due for a cleaning, November is the month to get it scheduled, because December fills up fast.
What is dental insurance actually for?
Before any of the details, one thing I want to be clear about. At the end of the day, insurance coverage should not dictate what treatment you get done. Its job is to improve your access to care and make it easier to afford, and that is the whole job. What your teeth need is decided in the chair, by looking at them, and the plan either helps pay for that or it does not.
Lately we have been seeing more and more plans fall short of that basic requirement. Maximums that have not moved in years, tighter frequency rules, and more things quietly moved into the "not covered" column. I am not saying that to talk you out of your plan. I am saying it so you go into year end with a clear picture: the benefits are worth using, and they are also not the thing that decides what is good for your mouth.
What actually resets on January 1?
Three things, and it helps to keep them separate in your head.
The first is the annual maximum. This is the cap on what your plan will pay toward your care in a year. If you have not used all of it by the end of the year, the rest does not get banked for you. It simply goes away, and you start the new year with a fresh cap. Most plans work this way, and it is the piece that catches people off guard, because you have been paying premiums all year for coverage you may not have touched.
The second is the deductible. That is the amount you pay out of pocket before the plan starts sharing the cost. If you met it in March when you had a filling done, the rest of this year's work is cheaper for you than it will be in January, when the deductible starts over from zero.
The third is frequency limits. Most plans cover two cleanings and exams a year, and a set of bitewing X-rays on a schedule. A second cleaning you never used in 2026 does not carry into 2027. It is just gone.
One caveat: not every plan runs January to December. Some employer plans run on a plan year that starts in, say, July. The reset still happens, it just happens on a different date, so check your plan if you are not sure which calendar you are on.
How do I find out how much I have left?
There are three easy ways. Your carrier's member portal or app will usually show your remaining maximum, your deductible status, and what preventive visits you have used. The phone number on the back of your insurance card gets you to someone who can read the same information to you. Or you can skip both and call or text us, and we can help you figure out what you have left.
We are in-network with Regence, Premera, and Delta Dental, and we accept most other plans. If you are not sure whether yours is one of them, that is a quick question for our front desk.
Does this mean I should get extra treatment before December?
No, and this is the part I care most about getting right.
The exam decides what your teeth need. The calendar does not. If you come in for a cleaning in November and everything looks healthy, the answer is a cleaning, a quick look at the X-rays, and a see-you-in-six-months. If there is a spot on a molar that we have been watching, and it has not changed, we keep watching it. Insurance that is about to expire does not turn a watch into a filling, and it does not turn a filling into a crown. I have written before about how to think about a second opinion on a crown, and the same principle applies here: the tooth has to earn the treatment on its own.
What the calendar does change is the timing of work that is already in your plan. The crown I recommended in August that you have been meaning to get to. The composite filling you postponed over the summer. The cleaning you have not scheduled yet. Those are real needs that exist whether or not it is the end of the year. Finishing them this year, while your deductible is met and your maximum is sitting there unused, just means you are missing out on benefits you have already paid for.
What if I have a bigger treatment plan?
The same rules apply. The exam decides what needs doing, and the clinical picture sets the order. A tooth that hurts goes first. A crack that is spreading goes before one that is stable. Anything cosmetic waits until the health problems are handled.
What changes with a bigger plan is how much it matters that you actually use your benefits. Whatever your plan would have paid in December is gone on January 1, so the work it would have covered slides into next year and takes a bite out of next year's maximum, which pushes the work behind it further still. That is how people end up feeling like they are on a never-ending treatment treadmill. It is usually not that new problems keep appearing. It is that the plan keeps starting over without ever catching up. Using what you have each year is how you get off that treadmill.
It helps to remember what dental insurance is designed for. It is built around maintenance: two cleanings, exams, X-rays, and modest help with the occasional repair. It was never meant to cover a large amount of restorative work in one year, which is why the annual maximum is as low as it is. So when there is more to do than one year's maximum will cover, finishing part of it in December under this year's benefits and the rest in January under next year's is the practical way to work with that design instead of against it.
One thing worth knowing about runway. A same-day CEREC crown is one visit, start to finish, so it can fit into a December schedule. A root canal followed by a crown is typically two visits. A dental implant is several visits spread over months. Planning matters, so if you have any questions at all, reach out.
What about an FSA or HSA?
If you have a flexible spending account through work, those dollars usually expire at the end of the year too. Some employers allow a short grace period into the new year, or a small carryover, but not all of them do, so check with your HR department or your plan documents.
A health savings account is different. HSA money rolls over year to year and stays yours. Dental treatment is generally an eligible expense for both types of account, which means a crown or a cleaning paid from one of them is money you had already set aside for exactly this.
Why November and not December?
A few reasons, all practical. Hygiene appointments fill first, because everyone who put off a cleaning remembers at the same time. The holidays shorten the month, so there are fewer working days than it looks like on the calendar. And multi-visit treatment needs enough runway to finish before the 31st, which a late December start usually does not have. December fills up quickly for us every year.
That said, a December call is still worth making. Things open up when people travel, and a single-visit crown or a cleaning can often slide into a gap. The worst outcome is assuming it is too late and not asking.
Year-End Benefits FAQ
Does my unused annual maximum roll over?
For most plans, no. Whatever is left on December 31 is gone, and you start fresh on January 1. A small number of plans offer a rollover feature that carries a portion forward if you had a preventive visit during the year, so check your plan, but assume it does not unless you confirm otherwise.
How do I know if my plan is calendar year or plan year?
Your plan documents or member portal will say. If your benefits started on a date other than January 1, you may be on a plan year. The front desk can also often see this when we verify your coverage, so ask when you call.
Can I still get in if I call in December?
Often, yes. It depends on what you need and how much time it takes. Cleanings and same-day crowns fit into gaps more easily than treatment that needs multiple visits. Call and we will tell you what is realistic.
Do you take my insurance?
We are in-network with Regence, Premera, and Delta Dental, and we accept most other PPO plans. If you are not sure, call or text us with your carrier's name and we can check before you come in.
I have not been in all year. Is it too late to use my benefits?
Not at all. Your preventive visits are sitting there unused, and a new patient exam with a cleaning is exactly what those benefits are for. If it has been longer than a year, I wrote a post for people who have not been to the dentist in a while, and the short version is that nobody here is going to make you feel bad about it.
If you want to use your benefits before the end of the year, call or text 425.643.5778 or request an appointment. Tell us that is what you are calling about, and we can help you figure out what you have left and what makes sense to schedule.
