Updated October 13, 2026

December 31 is the last day many dental plans will pay for this year’s care. If your plan runs on the calendar year, your dental insurance benefits expire at the end of the year. Whatever is left of your annual maximum usually doesn’t carry into January. So if you’ve put off a crown, a deep cleaning, or a filling, the next few weeks matter.

Below, you’ll see how to tell when your plan resets and why a crown has to be finished before the deadline. You’ll also see what’s worth booking now and how our $100 off crown copay works with what your insurance pays.

Direct Answer

On calendar-year plans, dental insurance benefits expire December 31, when the deductible and annual maximum reset. Work counts on the day it’s finished, so a crown only uses this year’s benefits if it’s cemented before the reset. Book crowns and root canals first, then cleanings and fillings.

TL;DR

  •         Many dental plans reset on January 1, so unused benefits expire December 31. Policy-year plans reset on their start date [1].
  •         A crown counts on the day it’s cemented, so begin crown and bridge work early [3].
  •         Only about 3% of people reach their annual maximum, and 73% of PPO members have a maximum of $1,500 or more [2][5].
  •         Book the longest jobs first: crowns, bridges, root canals, and deep cleanings, then fillings and checkups.
  •         Insured patients get $100 off the copay for crown and bridge work at Sunset Dental, after insurance pays its share [11].
  •         FSA money is use-or-lose, with up to $680 of carryover for 2026 plans if your employer allows it. HSA money doesn’t expire [12][13].

One liner: Check your reset date, start crown work now so it’s finished in time, and let the $100 off crown copay cut what’s left.

When Does Dental Insurance Reset? Calendar Year vs Plan Year

In short: Calendar-year plans reset January 1. Policy-year plans reset on their start date.

Many dental plans run on a calendar year, from January 1 to December 31. On those plans, Delta Dental notes, your deductible and annual maximum reset on January 1 [1]. Plans on a policy year (also called a plan year) work differently. They start the day your coverage begins and reset one year later [1].

  Calendar-year plan Policy-year plan
Benefit period January 1 to December 31 [1] Starts the day your coverage begins and runs one year [1]
When it resets January 1 Your plan’s start date, every year
What resets Deductible and annual maximum [1] Deductible and annual maximum [1]
Last day to use this year’s benefits December 31 The day before your plan’s start date

 

Say your employer’s plan starts on July 1. Then your benefits reset every July 1, and your real deadline is June 30. Coverage limits, such as how many cleanings your plan pays for, apply inside that same benefit period too [1].

If you’re on a dental HMO (DHMO), you may have no maximum to lose. NADP data shows that in 2024, 88% of people enrolled in dental HMOs had no annual maximum at all [2]. Your coverage limits still run by benefit period, though, so the reset date still matters.

Not sure which kind of plan you have? Check your plan’s member website or the benefits summary from your employer. The phone number on the back of your insurance card works too.

Your Crown Counts the Day It’s Cemented, Not the Day It’s Started

In short: A crown uses this year’s benefits only if it’s cemented before your plan resets.

Starting a crown before December 31 isn’t enough to use this year’s benefits. Under Delta Dental’s handbook for dentists, a crown counts on the day the final crown is cemented in place [3]. The handbook puts it plainly: “Multistage procedures are reported and benefited upon completion” [3]. For crowns and bridges, completion is “the cementation date of the final restoration” [3].

Here’s how dental crowns in Ventura work at our office. At the first visit, we prepare the tooth and take an impression or digital scan. A lab then makes your crown, and at the second visit we place it [4]. The benefit year that counts is the one you’re in on that second visit.

Here’s how two dates change the math for the same crown:

  Patient A Patient B
First visit (tooth prepared) November 20 December 18
Crown cemented December 11 January 8
Which year’s maximum pays This year’s Next year’s
This year’s unused maximum Put to work Usually lost on a calendar-year plan

 

Root canal therapy follows a similar rule. It counts on the day the canals are permanently filled [3]. So if a tooth needs a root canal and then a crown, both have to be finished before your plan resets.

If a crown or bridge is on your treatment plan, book the first visit as soon as you can. Ask us how long the lab needs for your crown, too. If your plan is with a company other than Delta Dental, ask them how they date crowns before you count on this year’s maximum.

How Much Is Left? Your Dental Insurance Annual Maximum and Deductible

In short: Few people use their whole maximum, and most PPO maximums are $1,500 or more.

You’ve paid premiums for this coverage all year, so benefits left on the table are money you’ve already spent. Your annual maximum is the most your plan will pay toward your care in one benefit year. Few people use all of it. In NADP’s latest figures, 2.9% of people in group dental PPO plans reached their maximum [2]. The ADA’s Health Policy Institute puts the share of patients who reach a typical maximum at 3.4% [5].

Maximums are also bigger than many people assume. Nearly three in four people in dental PPOs (73%) have an annual maximum of $1,500 or more [2]. Some plans still sit at the $1,000 level set about 40 years ago [5]. Check your own number instead of guessing.

Delta Dental defines your deductible as “the dollar amount you must pay for covered dental services before your dental plan starts to pay” [6]. It resets every 12 months [6]. Many plans don’t apply it to exams, cleanings, and other preventive care [6]. If you’ve already met this year’s deductible, work you finish before the reset won’t need it again.

After the deductible, your plan pays a share of each service. The share you pay is called coinsurance. Here’s one common setup, from a Delta Dental plan example [7]:

Service tier Examples Plan pays You pay
Preventive Cleanings and checkups 100% 0%
Basic Fillings 80% 20%
Major Crowns, root canals, deep cleaning 50% 50%

 

Your plan’s split may differ. Here’s the math on an 80% service: for a $250 service with a $50 deductible, the plan pays $160 and you pay $90 [6].

To see what’s left for this year, log in to your plan’s member site or call its customer service team [20]. Before bigger work like a crown, ask for a pre-treatment estimate. It shows roughly what the treatment will cost and how that cost splits between you and your plan [21].

What to Book Now to Use Dental Insurance Before End of Year

In short: Book crowns, bridges, root canals, and deep cleanings first, then fillings and checkups.

Book the longest jobs first. A crown needs two visits with lab time in between [4], so it has the least room to slip. Shorter visits can fit in around it.

Treatment Why it matters now When to book Tier in one example plan [7]
Crowns and bridges They count only once they’re cemented [3] First visit as soon as you can Major
Root canal therapy It counts once the canals are filled [3], and a crown may follow [10] Now, so there’s time for a crown Major
Deep cleaning It treats buildup around and below the gumline [8] Soon, and ask how many visits you’ll need Major
Fillings They use basic coverage before it resets Any time before your plan resets Basic
Exam, X-rays, and cleaning Preventive care is often paid in full [7] Early, so any follow-up fits before the deadline Preventive

 

If you haven’t had a checkup this year, start there. Our exams and digital X-rays can show concerns you can’t see in a visual check [9]. A problem found in November can still be treated on this year’s plan.

Check your cleaning limit too. If your plan covers two cleanings a year and you’ve had one, the second one disappears when the plan resets [1].

If we’ve recommended a deep cleaning, don’t let it slide into January. It targets buildup around and below the gumline when extra gum care is needed [8]. In the example plan above it’s a major service [7], so leftover maximum can cover a real share of it.

Switching dental plans at open enrollment? Finish major work on your current plan first. A new plan can come with a waiting period, and Delta Dental says 12 months is often standard for major services such as crowns [19]. It may be waived if you had comparable coverage that ended within 30 to 60 days of the new plan starting [19].

How the $100 Off Crown Copay Works With Your Remaining Benefits

In short: Your plan pays its share first, then $100 comes off your crown or bridge copay.

If you have dental insurance, we take $100 off your copay for crown and bridge work [11]. Your copay is the share left for you after your plan pays. So your insurance pays its part from this year’s maximum first, and the $100 comes off what’s left.

Here’s how that plays out on a crown. The numbers are examples only. Both columns assume a plan that pays 50% for major work [7] and a deductible that’s already met.

  Plenty of maximum left Only $400 of maximum left
Crown fee (example) $1,200 $1,200
Plan pays $600 $400
Your share before the offer $600 $800
$100 off crown copay Minus $100 Minus $100
You pay $500 $700

 

The right column is the one to watch in December. Even $400 of leftover maximum takes a real bite out of the cost, and the $100 still comes off your share. Whatever your plan won’t cover is where a payment plan can help.

The fine print is short. The offer is “for insured patients only” and “may not be combined with other offers” [11]. It works the same way for bridges as for crowns [11]. Our current specials page has the full details.

FSA and HSA Dollars: What Expires and What Doesn’t

In short: FSA money is use-or-lose with limited extra time. HSA money doesn’t expire.

A health flexible spending account (FSA) runs on a use-or-lose rule. In the IRS’s words, “Amounts not used by the end of the plan year are forfeited” [13]. Your employer may soften that with a grace period of up to 2 1/2 months [13] or with a carryover. For 2026 plans, the IRS caps the carryover at $680 [12].

A health savings account (HSA) works differently. The IRS puts it simply: “The contributions remain in your account until you use them” [13]. There’s no year-end deadline on HSA money.

  Health FSA HSA
Does unused money expire? Yes, at the end of the plan year, unless your plan allows extra time [13] No, it stays in your account [13]
What can carry over Up to $680 from a 2026 plan, if your employer allows it [12] Your balance, generally [13]
What to check before year end Your plan’s grace period or carryover rule, with HR Nothing, unless you want to spend it now

 

Dental care counts. The IRS treats what you pay to prevent and treat dental disease, such as cleanings, X-rays, and fillings, as a medical expense [14]. Teeth whitening doesn’t count [14]. So FSA dollars can cover the share left after insurance, including a crown copay after the $100 off.

When Treatment Costs More Than Your Benefits Cover

In short: Spread work across two benefit years when it’s safe, or use a payment plan.

Sometimes the work you need costs more than one year’s maximum. You have two good options.

The first is timing. Your maximum resets, and work counts on the day it’s finished [1][3]. So spreading several treatments across the reset can draw on two years of benefits. This only makes sense when Dr. Atanay says it’s safe for some of the work to wait.

Here’s how it looks for three crowns on a calendar-year plan:

  All three crowns this year Two now, one after the reset
Crowns finished by December 31 3 2
Crowns finished after January 1 0 1
Maximums used This year’s only This year’s and next year’s

 

The second is a payment plan. For dental payment plans, Ventura patients can talk with our team, and “payment plan details are discussed before any treatment begins” [11]. That way, the share your insurance doesn’t cover can be spread out instead of paid all at once [15].

Frequently Asked Questions

In short: Most plans reset January 1, a crown counts when it’s cemented, and FSA money is use-or-lose while HSA money carries over.

Do dental insurance benefits expire end of year?

On calendar-year plans, yes. Unused benefits expire December 31, and your deductible and annual maximum reset January 1. Policy-year plans reset on the date your coverage started instead [1].

Do unused dental benefits roll over?

Usually not. Some plans have a rollover feature that moves part of your unused maximum into the next year [18], so check your plan documents before you count on it.

Does a crown started in December count toward this year’s benefits?

Only if it’s cemented by the time your plan resets. Delta Dental dates a crown by “the cementation date of the final restoration” [3].

Does my dental deductible reset in January?

On calendar-year plans, yes. A dental deductible resets once every 12 months, and many plans follow the calendar year [6].

Can I use my FSA for a crown or other dental work?

Yes. The IRS counts what you pay to prevent and treat dental disease as a medical expense, so FSA funds can cover your share. Teeth whitening doesn’t qualify [14].

Can the $100 off crown copay be combined with other offers?

No. The offer is for insured patients only and may not be combined with other offers [11].

How do I find out how much of my dental benefits are left?

Log in to your plan’s member site or call its customer service team [20]. Before a crown or other big work, ask for a pre-treatment estimate, which shows roughly how the cost splits between you and your plan [21].

Is there a waiting period if I switch dental plans?

Often, for bigger work. A 12-month wait is often standard for major services like crowns, while preventive care typically has none [19]. A waiting period may be waived if comparable coverage ended 30 to 60 days before the new plan starts [19].
