Yes, you can use a health savings account (HSA) or a health flexible spending account (FSA) for most dental work. The IRS counts the prevention and treatment of dental disease as medical care. That covers routine visits, fillings, extractions, braces and dentures. The one thing it names as not eligible is teeth whitening.
Paying with pre-tax money is one of the few legal discounts on dental care you get without negotiating. If your income is taxed at 22%, paying a $1,300 crown from an HSA or FSA saves you about $286 in federal income tax compared with paying from your paycheck after tax. With dental prices up 5.0% in the past year, according to our dental price index, that discount is worth using.
What dental costs count
HSAs and FSAs pay for “medical care” as the tax code defines it, and IRS Publication 502 spells out what that means for teeth. You can include amounts you pay “for the prevention and alleviation of dental disease.”
Named as eligible in Publication 502:
- Teeth cleaning
- Sealants
- Fluoride treatments
- X-rays
- Fillings
- Braces
- Extractions
- Dentures
The list is examples, not a complete catalog; the IRS adds “other dental ailments.” Treatments like crowns, root canals, bridges and implants aren’t named, but they treat dental disease. Your plan administrator decides individual claims, so check your plan’s list of eligible expenses before paying for a large one.
Named as not eligible: teeth whitening. In the IRS’s words, “You can’t include in medical expenses amounts paid to whiten teeth.” Other work done purely for appearance is a gray area worth asking about before you assume your plan will pay.
For what these treatments cost, see our guides to braces, dentures and fillings.
HSA vs. FSA: the differences that matter for dental
| HSA | Health FSA | |
|---|---|---|
| Who can have one | Only people covered by a high-deductible health plan (HDHP) | Offered through an employer |
| 2026 contribution limit | $4,400 self-only, $8,750 family | $3,400 |
| Unused money | Carries over year to year | Generally lost at the end of the plan year (see below) |
| When the money is available | As it’s deposited | Your full annual election, from the start of the plan year |
| Who it can pay for | You, your spouse, and dependents you claim | Set by your plan |
If you have an HSA, there’s no deadline. Money you don’t spend this year stays in the account, so you can build it up ahead of a big treatment like an implant.
If you have an FSA, the deadline is the whole game. Publication 969 describes FSAs as generally “use-it-or-lose-it” plans. Your plan can soften that in one of two ways, but not both:
- A grace period of up to 2½ months after the plan year ends, during which new expenses can still be paid from last year’s balance.
- A carryover of unused money into the next plan year. For 2026 plan years, the maximum carryover is $680, and your plan can set a lower amount.
Some plans offer neither. Look up your plan’s rule and your remaining balance now, not in late December.
Have both? You generally can’t contribute to an HSA while you’re covered by a regular health FSA. But Publication 969 allows a limited-purpose FSA alongside an HSA, and dental care is one of the things it can pay for.
How to time dental work to save the most
- Spend down this year’s FSA on care you need anyway. If you have money left and your plan year ends December 31, book the cleaning, the X-rays, or the filling your dentist has been watching. Don’t book treatment you don’t need just to spend the balance.
- Size next year’s FSA election to your dental plan. Open enrollment for workplace benefits usually happens in the fall. If your dentist has already recommended a crown or implant for next year, ask for a written estimate and elect enough to cover your share.
- Use the FSA’s front-loading. Publication 969 says you must be able to get the full amount you elected “at any time during the coverage period, regardless of the amount you have actually contributed.” A treatment in January can be paid in full from an FSA you’ll fund over the rest of the year, with no interest and no credit card.
- Let insurance pay first, then use the account for your share. Dental insurance usually pays a percentage up to an annual maximum. Your HSA or FSA can cover the coinsurance and anything above the cap. Our dental insurance calculator shows what your share of a treatment is likely to be.
- Keep every receipt. Plans and the IRS can ask you to show that a payment was for eligible care. An itemized receipt from the dental office that lists the procedures is the simplest proof.
No HSA or FSA? You may still get a tax break
If you itemize deductions, dental treatment counts toward the medical and dental expense deduction. According to Publication 502, you can generally deduct only the part of your total medical and dental expenses that is more than 7.5% of your adjusted gross income, so it mostly helps in a year with large bills. A tax professional can tell you whether itemizing makes sense for you.
