Are Dental Expenses Tax Deductible? AGI Floor and Limits

Yes, dental expenses are tax deductible on your federal return, but with two significant limits: you can only deduct the portion of your combined unreimbursed medical and dental costs that exceeds 7.5% of your adjusted gross income (AGI), and you have to itemize deductions on Schedule A to claim any of it.¹ Because most filers take the standard deduction, routine cleanings and fillings rarely produce a tax break. A year with implants, braces, or oral surgery is a different story.

What Dental Expenses Qualify

IRS Publication 502 sets the boundaries. Qualifying costs cover both preventive care and treatment for dental disease: cleanings, fluoride treatments, sealants, diagnostic X-rays, fillings, crowns, extractions, dentures and bridges, braces and other orthodontic work, oral surgery, and dental implants.² Equipment your dentist prescribes to treat a specific condition, such as a specialized oral irrigator after gum surgery, also counts. Everyday personal care items like regular toothbrushes and toothpaste do not.

You can deduct qualifying costs you paid for yourself, your spouse, or a dependent. Covering an adult child’s emergency root canal or a parent’s dentures counts as long as that person qualifies as your dependent under IRS rules. The expense has to be unreimbursed, so subtract anything paid by insurance, an HSA, or another source before you run the numbers.

Cosmetic Dentistry Usually Doesn’t Count

The IRS draws a clear line between restoring function and improving appearance. Teeth whitening is specifically listed as non-deductible even when a dentist performs it.² Porcelain veneers and cosmetic bonding placed only to change how a smile looks fall on the same side of the line.

The test is whether the procedure meaningfully promotes proper function of the body or treats a disease. A crown on a cracked tooth restores function and qualifies. A veneer over a healthy tooth to straighten its appearance does not. When a procedure does both, like an implant that replaces a missing tooth and also improves appearance, the IRS generally treats it as deductible because the primary purpose is restoring function.

One exception matters: cosmetic dental work is deductible when it corrects a deformity from a birth defect, an injury, or a disfiguring disease.¹ Reconstructive dental work after a car accident qualifies even if it also improves how you look.

The 7.5% AGI Floor

You do not get to deduct dental spending from dollar one. The deduction applies only to the amount by which your combined medical and dental expenses exceed 7.5% of your AGI.¹

With an AGI of $60,000, the floor is $4,500. If your unreimbursed medical and dental costs for the year total $8,000, you can deduct the $3,500 above the floor.³ Higher incomes need proportionally bigger bills before anything becomes deductible. At $150,000 AGI, you need to clear $11,250 before the first dollar counts. At $40,000, the threshold is $3,000. Years with expensive procedures, like implants that often run $3,000 to $7,000 per tooth or a full course of orthodontics, are when this deduction is most likely to help.

You Have To Itemize

None of this matters unless you itemize on Schedule A. Take the standard deduction and the dental write-off disappears.⁴ For the 2026 tax year, the standard deduction is $16,100 for single filers and those married filing separately, $32,200 for married filing jointly, and $24,150 for heads of household.⁵

Itemizing pays off only when your total itemized deductions (medical and dental above the 7.5% floor, plus mortgage interest, state and local taxes, and charitable contributions) come out ahead of your standard deduction.⁶ You make the choice each year, so a heavy dental year can tip you into itemizing even if you normally don’t.

Dental Insurance Premiums

Premiums you pay out of pocket for dental coverage count as deductible medical expenses, provided you paid them with after-tax dollars. If your employer takes the premium out of your paycheck pre-tax, that money is already excluded from your taxable income and cannot be claimed again.² The rule matters most for people buying individual dental plans outside work; a $600 annual premium paid with after-tax money goes into the medical expense total alongside your other qualifying costs.

The Self-Employed Get a Better Deal

If you’re self-employed, dental insurance premiums are deductible above the line, meaning you don’t have to itemize to claim them.⁷ The deduction covers dental, medical, and vision premiums for you, your spouse, and your dependents, and you calculate it on Form 7206 and report it on Schedule 1 of your Form 1040. It cannot exceed your net self-employment income for the year.

Premiums claimed here cannot also be included in itemized medical expenses on Schedule A. If some portion doesn’t fit on Schedule 1, though (for instance, because it exceeded your self-employment income), you can still add that portion to Schedule A if you itemize. Because the above-the-line version reduces your AGI directly, it also lowers the 7.5% floor for any remaining medical expenses you itemize.

HSAs and FSAs Are the Other Route

Health Savings Accounts and Flexible Spending Accounts let you pay for dental care with pre-tax dollars, and they cover the same procedures the itemized deduction covers: cleanings, fillings, crowns, braces, implants, and more. Expenses paid through these accounts cannot also be claimed as itemized deductions.² Treat them as an alternative tax benefit, not an addition.

For 2026, HSA contributions cap at $4,400 for self-only coverage and $8,750 for family coverage,⁸ and the health care FSA limit is $3,400.⁹ HSAs require enrollment in a high-deductible health plan and roll over indefinitely. FSAs come through an employer and generally follow use-it-or-lose-it rules within the plan year, though some employers offer a limited grace period or carryover.

For anyone taking the standard deduction, an HSA or FSA is often the only realistic way to get a tax benefit from dental spending. If you know a major procedure is coming, funding one of these accounts for the expected amount effectively discounts the work by your marginal tax rate.

When the Expense Counts

You deduct dental costs in the year you pay them, not the year you receive treatment.² Two situations catch people off guard.

Credit card charges count in the year you charge them, not the year you pay off the balance. A $5,000 implant charged in December 2026 is a 2026 expense even if you’re still paying the card down in 2027. Multi-year orthodontic payment plans work the opposite way: you deduct each payment in the year you make it, so $2,000 paid in 2026 and $2,000 paid in 2027 toward your child’s braces goes on each year’s return separately. You generally cannot prepay future treatment and take the whole thing at once. That spreading can work against you if neither year’s expenses clear the 7.5% floor on their own.

Travel for Dental Care

Getting to the dentist counts too. You can deduct 20.5 cents per mile for medical driving in 2026, plus tolls and parking, along with bus, taxi, train, and ambulance fares.¹⁰ If dental care requires overnight travel, lodging is deductible up to $50 per night, or $100 combined when a companion needs to travel with the patient. Meals during medical travel don’t qualify.²

How To Claim It

Dental expenses go on Schedule A (Form 1040) alongside your other medical costs. Enter the total unreimbursed amount on Line 1; the form then subtracts the 7.5% AGI floor and produces your deductible amount, which flows into your total itemized deductions.⁴ Self-employed premiums calculated on Form 7206 land instead on Schedule 1, Line 17 of Form 1040.⁷ The same premium dollars cannot appear on both.

Keep billing statements, proof of payment, and insurance explanations of benefits for at least three years after filing, which matches the general IRS audit window.¹¹ For expensive procedures that might look cosmetic on paper, hold onto notes from your dentist explaining medical necessity.
