Tax-Filing Season: Which Dental Costs Can Actually Be Deducted

The medical and dental expense deduction has a specific income threshold and specific rules about what counts. Most taxpayers who could claim it never do.

Evidence-led, fact-checkedPublished February 9, 2027
Start with this

The IRS allows a deduction for medical and dental expenses, but only for the portion that exceeds a set percentage of adjusted gross income, and only for taxpayers who itemize deductions instead of taking the standard deduction: both conditions that mean many taxpayers who paid substantial dental costs during the year still won't benefit from claiming them. Eligible dental expenses generally include most treatment with a legitimate dental-health purpose, but purely cosmetic procedures typically do not qualify. Expenses already reimbursed by insurance, an FSA, or an HSA cannot be deducted again on top of that reimbursement, only the portion actually paid out of pocket and not otherwise reimbursed counts toward the deduction, and keeping itemized records throughout the year makes that calculation far easier than trying to reconstruct it from memory the week a return is due.

Part 01

Tax-filing season: dental expense deductions need two conditions to both be true

The deduction only applies to the amount of qualifying medical and dental expenses that exceeds the IRS's set percentage threshold of adjusted gross income for that tax year, and even then it only helps a taxpayer who itemizes instead of taking the standard deduction. For many taxpayers, the standard deduction is simply larger.

Part 02

What generally counts as an eligible dental expense

Treatment with a legitimate dental-health purpose, exams, cleanings, fillings, extractions, orthodontics, dentures, and many other procedures, generally qualifies, while purely cosmetic procedures like teeth whitening typically do not, and the line for a mixed-purpose procedure isn't always obvious.

12 questions

Questions this raises

Do I need to itemize to deduct dental expenses?

Yes: the medical and dental expense deduction is only available to taxpayers who itemize deductions on Schedule A; it is not available alongside the standard deduction.

Can I deduct dental expenses paid with an FSA or HSA?

No: amounts already paid through a tax-advantaged account like an FSA or HSA have effectively already received a tax benefit and cannot also be claimed as an itemized deduction.

Is teeth whitening a deductible dental expense?

Generally no: purely cosmetic procedures like teeth whitening typically don't qualify, since the deduction is intended for expenses with a legitimate dental-health purpose.

What counts toward the AGI threshold calculation?

Total qualifying unreimbursed medical and dental expenses for the household during the tax year are compared against the set percentage of adjusted gross income; only the amount above that threshold is potentially deductible.

Can I deduct dental insurance premiums?

In some cases yes, particularly certain self-employed health insurance situations or premiums paid with after-tax dollars, but the specific rules depend on how the premium is paid. Check current IRS guidance or a tax professional.

Do braces or orthodontic treatment for a child qualify?

Generally yes, orthodontic treatment with a legitimate dental-health purpose is commonly an eligible expense, subject to the same itemization and threshold rules as other dental costs.

What records do I need to keep for a dental expense deduction?

Itemized receipts or statements showing the date, the specific procedure or service, and the amount paid out of pocket. A general credit card statement alone is typically not sufficient documentation.

Does the deduction apply per person or per household?

It's generally calculated on the total qualifying expenses for the taxpayer, spouse, and dependents combined against the household's adjusted gross income, not calculated separately per individual.

Can I deduct dental expenses for a prior year on this year's return?

Generally, expenses are deducted in the tax year they were actually paid, not the year the treatment was received if those differ. Confirm the specific timing rule with a tax professional.

Is dental implant treatment eligible for the deduction?

Dental implants performed for a legitimate dental-health purpose are generally eligible, similar to other restorative dental treatment, subject to the same itemization and AGI threshold rules.

Does the deduction threshold change from year to year?

The threshold is currently 7.5 percent of adjusted gross income, as IRS Publication 502 explains. It is set by tax law and has changed in the past, so confirm the figure for the year you are filing rather than relying on an earlier one.

Should I consult a tax professional even for a straightforward dental deduction?

For anything beyond simple, clearly-documented expenses, a tax professional can confirm current thresholds, forms, and edge cases. The general structure is explained here, not a substitute for that advice.
