Dental work is a qualified medical expense. That part is settled and has been for decades. The problem is the threshold sitting in front of it, which is high enough that most people who ask this question end up deducting nothing.
Everything below was verified against IRS pages and published dental fee schedules on September 6, 2026. Publication 502 for 2025 is the current revision, and the dollar limits are labeled by tax year because a reader in September 2026 is either amending a 2025 return or planning for the 2026 return filed in 2027.
The 7.5% Floor Is the Whole Story
The Instructions for Schedule A (Form 1040) for 2025 put it in one line: you can deduct only the part of your medical and dental expenses that exceeds 7.5% of your adjusted gross income. Publication 502 says the same thing.
That is a floor, not a cap. On a $60,000 AGI, the first $4,500 of combined medical and dental spending is invisible to the deduction. Only dollar 4,501 onward counts.
Then there is a second gate. Schedule A is the itemizing schedule, so the deduction only helps if your total itemized deductions beat the standard deduction. Revenue Procedure 2025-32 sets the tax year 2026 standard deduction at $16,100 for single filers and married filing separately, $24,150 for heads of household, and $32,200 for joint filers. For tax year 2025 the same document records $15,750, $23,625 and $31,500. Clearing both the floor and the standard deduction on dental bills alone is rare.
What Dental Work Qualifies
Publication 502’s Dental Treatment entry is broader than most people expect. It covers amounts you pay for the prevention and alleviation of dental disease, and it splits into two lists.
Preventive: services of a dental hygienist or dentist for teeth cleaning, application of sealants, and fluoride treatments to prevent tooth decay.
Treatment: services of a dentist for procedures such as X-rays, fillings, braces, extractions, dentures, and other dental ailments.
Dental implants are not named in that sentence but fall squarely inside “other dental ailments” as restorative treatment for a missing tooth, and the same logic covers crowns, root canals and bridges. Sedation, anesthesia and the oral surgeon’s fee travel with the procedure. So does mileage to and from the appointment, at the standard medical rate of 21 cents a mile for 2025.
What Does Not Qualify
Publication 502 names teeth whitening directly, in the What Expenses Aren’t Includible section: you can’t include in medical expenses amounts paid to whiten teeth. It cross-references Cosmetic Surgery, which is only includible when the procedure corrects a congenital abnormality, a personal injury from an accident or trauma, or a disfiguring disease.
That is the line. Whitening, and cosmetic work whose only purpose is appearance, sits outside. A crown that restores a cracked molar is treatment. A veneer placed purely for looks is not. If a single visit includes both, only the treatment portion counts, and you need the office to break out the charges.
Dental Insurance Premiums
Publication 502’s Insurance Premiums section says you can include premiums you pay for policies that cover medical care, and it lists dental care among the treatments those policies can pay for. So a standalone dental policy you buy yourself, with after-tax dollars, is includible.
Three things knock premiums out. The Schedule A instructions say you can’t include insurance premiums paid by making a pretax reduction to your employee compensation, so payroll-deducted premiums are already untaxed and cannot be deducted twice. Publication 502 says not to include employer-paid premiums unless they show up on your Form W-2. And it says you can’t include premiums for which you are claiming a credit or another deduction, which is why the Schedule A instructions tell you to reduce your premiums by any self-employed health insurance deduction claimed on Schedule 1, line 17.
Whether a dental policy is worth buying at all is a separate question, covered in dental insurance cost.
What Dental Work Actually Costs, and What It Takes to Clear the Floor
Here is the numbers-first part. Careington publishes a sample fee schedule on its plan pages, and states on one of them that the regular cost column reflects the average 80th percentile usual and customary rates in the 2024 FAIR Health report. Two of its regional pages, both read September 6, 2026, carry different figures for the same procedures, which is a useful illustration of how much geography moves dental prices. Guardian’s separate table cites a 2024 Synchrony average procedural cost study.
| Procedure | Careington published range | Guardian (2024 Synchrony) |
|---|---|---|
| Routine checkup | $76 to $93 | $203 for exam plus cleaning |
| Four bitewing X-rays | $92 to $101 | not listed |
| Adult cleaning | $133 to $152 | included above |
| Composite filling, front tooth | $215 to $239 | $226 |
| Extraction, single tooth | $266 to $305 | $177 simple, $363 surgical |
| Crown, porcelain fused to noble metal | $1,556 to $1,662 | $1,399 |
| Molar root canal | $1,638 to $1,692 | $1,165 |
| Single implant | not listed | $2,695 |
The two sources disagree by roughly a third on crowns and root canals, and Careington’s own pages disagree with each other by about 3%, so read these as a band rather than a price. They also disagree wildly on dentures (Careington lists a complete upper denture at $2,299 to $2,436, Guardian lists basic dentures at $452), which almost certainly reflects different scope, so we have left that row out. Our own cash-price research is in root canal cost without insurance and dental implant cost without insurance.
Worked example, tax year 2026. Single filer, AGI $60,000, no other medical spending. The 7.5% floor is $4,500.
A genuinely bad dental year: two cleanings plus a checkup and one set of bitewings ($498), one composite filling ($239), one molar root canal ($1,692), the crown that goes over it ($1,662), and one implant elsewhere in the mouth ($2,695). Total: $6,786.
Subtract the floor and $2,286 is deductible. At a 22% marginal rate that is worth $503, but only if the filer’s total itemized deductions already exceed $16,100, meaning roughly $13,800 of mortgage interest, state taxes and charity before the dental bills are added. For a renter, the deduction is worth exactly zero on a $6,786 dental year.
The HSA and FSA Route Beats the Deduction
An HSA or health FSA has no AGI floor and no itemizing requirement. Money goes in before tax and comes out tax free for dental care, so every dollar counts from the first one.
For 2026, Revenue Procedure 2025-19 sets HSA contributions at $4,400 for self-only coverage and $8,750 for family coverage, plus $1,000 if you are 55 or older. Revenue Procedure 2025-32 sets the health FSA salary reduction limit at $3,400 with a $680 carryover. Publication 969 confirms HSA distributions are tax free when used for qualified medical expenses, which is the same Publication 502 list that covers dental.
Run the same $6,786 dental year through a health FSA and the first $3,400 of it is bought with pre-tax payroll dollars. At 22% federal plus 7.65% FICA that is about $1,008 of tax saved, on less than half the spending, with no floor and no Schedule A. The deduction path returned $503 and only for an itemizer.
Two practical notes. HSA eligibility requires a qualifying high deductible plan, and the FSA is use-it-or-lose-it beyond the carryover. If you are on an HSA plan already, a limited-purpose FSA can be stacked on top specifically for dental and vision. The mechanics are in HSA vs FSA and Form 8889, and the broader Schedule A rules are in the medical expense tax deduction guide.
Dental Savings Plans Are Not Insurance
A dental savings plan charges an annual membership fee and gives you a discounted fee schedule at participating dentists. Careington’s plan pages state it plainly: THIS PLAN IS NOT INSURANCE and is not intended to replace health insurance, and members pay the provider directly to receive the discount.
That distinction decides the tax question. Publication 502 allows exactly two things here: amounts paid for dental treatment, and premiums for policies that cover medical care. A membership fee is neither. It does not pay a dentist and it is not a premium for a policy that provides payment for treatment, so it does not fit either category, and Publication 502 does not list discount or membership fees anywhere among includible expenses. Treat the annual fee as nondeductible, and if you are claiming it anyway, run it past a preparer first.
The discounted amount you then hand the dentist is a normal, fully qualified dental expense. Whether the membership pays for itself at all is a separate math problem, worked through in dental savings plans.
The Bottom Line
The honest answer for most households is that dental expenses are technically deductible and practically not, because the 7.5% floor and the standard deduction between them absorb a normal bad dental year. Run the numbers before you assume otherwise.
Where the deduction does land is a catastrophic year: full-mouth reconstruction, implants, a nursing home stay, or a self-employed filer with a large premium already on Schedule A. In those years, keep every receipt, including mileage and the dental portion of any bundled bill.
For everyone else, the money is in the pre-tax accounts and in the price itself. Lower the bill before you try to deduct it: free and sliding-scale dental clinics and dental grants exist for exactly this, and a long-term-care angle on the same Schedule A math is in is long-term care insurance tax deductible.
