Most dental expenses are not tax deductible, but some are if you itemize deductions and meet specific IRS rules

The IRS allows you to deduct dental and other medical expenses, but only if two things are true: you itemize deductions on your tax return instead of taking the standard deduction, and your total medical expenses for the year exceed 7.5% of your adjusted gross income (AGI). This means most people cannot deduct dental work because either their medical costs do not reach that threshold, or itemizing does not save them money compared to the standard deduction.

For example, if your AGI is $60,000, you would need more than $4,500 in combined medical and dental expenses before you could deduct any of them. Even then, you only deduct the amount above that 7.5% floor. Because dental insurance and preventive care are relatively affordable for many people, hitting this threshold is uncommon unless you have major dental work, ongoing treatment, or other significant medical costs in the same year.

Key Takeaways

  • Dental expenses are only deductible if you itemize deductions and your total medical expenses exceed 7.5% of your adjusted gross income.
  • Preventive care like cleanings and X-rays, orthodontia, root canals, crowns, and dentures all count as deductible medical expenses if you meet the threshold.
  • Cosmetic dental work such as teeth whitening and veneers placed purely for appearance are never deductible.
  • You must keep receipts and statements from your dentist showing what you paid out of pocket, including amounts your insurance did not cover.
  • The standard deduction is usually larger than itemized deductions for most taxpayers, which is why few people benefit from deducting dental costs.

What dental expenses count as deductible medical costs

The IRS considers dental work a medical expense if it treats or prevents disease of the teeth or gums. This includes routine cleanings, fillings, root canals, extractions, crowns, bridges, dentures, and braces or other orthodontia. If your dentist recommends the work to maintain or restore oral health, it generally qualifies.

Dental implants are deductible because they replace missing teeth and restore function. The cost of the implant itself, the abutment, and the crown all count. Periodontal (gum) disease treatment is deductible. Teeth whitening and cosmetic veneers placed solely to improve appearance are not deductible, even if your dentist performs them. The distinction is whether the work treats a health problem or only changes how your teeth look.

Orthodontia for children and adults is deductible if it corrects a medical condition — misalignment that affects chewing or speech, for example. Some orthodontists and dentists will note on your invoice whether work is cosmetic or therapeutic; ask for this distinction in writing if you plan to deduct it.

How the 7.5% threshold works and why it matters

You can only deduct medical expenses that exceed 7.5% of your AGI. Your AGI is your total income minus certain deductions like contributions to a traditional IRA or student loan interest. The IRS subtracts 7.5% of your AGI from your total medical expenses, and you deduct only what remains.

If your AGI is $50,000, the threshold is $3,750. If you spent $4,500 on dental work and other medical costs combined, you could deduct $750 ($4,500 minus $3,750). If you spent $3,500, you cannot deduct any of it because it does not exceed the threshold. This floor exists for most taxpayers, which is why dental deductions are rare unless you have major procedures, multiple family members with dental work, or other medical expenses in the same year.

Expenses covered by insurance do not count toward the threshold — only what you paid out of pocket. If your dental insurance covered $2,000 of a $3,000 crown, you count only the $1,000 you paid. Copays, deductibles, and coinsurance all count as out-of-pocket costs.

Itemizing deductions versus the standard deduction

Even if your dental expenses exceed the 7.5% threshold, you only benefit from deducting them if itemizing produces a larger deduction than taking the standard deduction. The standard deduction is a flat amount the IRS allows you to subtract from your income without listing individual expenses. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly, though these amounts change each year.

If your itemized deductions (medical expenses plus mortgage interest, state and local taxes, charitable donations, and other may have access to expenses) total more than the standard deduction, itemizing saves you money. Most people find that the standard deduction is larger, so they do not itemize. This is why dental deductions help only a small number of taxpayers — usually those with significant medical costs, high mortgage interest, or large charitable donations in the same year.

You choose one method or the other on your tax return; you cannot use both. A tax professional can calculate which approach saves you more money in your specific situation.

What you need to keep for documentation

If you deduct dental expenses, the IRS expects you to have receipts and statements showing what you paid. Keep invoices from your dentist that list the date, the service provided, the total cost, and the amount you paid out of pocket (after insurance). If your insurance paid part of the bill, the statement should show both the insurance payment and your portion.

You do not send these documents with your tax return, but you must have them if the IRS asks questions about your deduction. Keep them for at least three years after you file. If you had multiple dental visits or procedures, organize them by year so you can quickly add up your total out-of-pocket spending.

If you paid for dental work for a spouse or dependent child, those expenses count toward your household total as long as you could claim them as a dependent at the time of treatment. Keep records showing the relationship and the dependent's name and Social Security number.

Dental insurance premiums and what they cover

Premiums you pay for dental insurance are generally not deductible as a medical expense on your personal tax return. However, if you are self-employed, you may be able to deduct dental insurance premiums as part of the self-employed health insurance deduction, which has different rules than itemized medical deductions. This deduction does not require you to meet the 7.5% threshold.

If your employer offers dental insurance and deducts the premium from your paycheck before taxes, the premium is already excluded from your taxable income, so you do not deduct it again. Out-of-pocket costs you pay for dental work — copays, deductibles, and procedures not covered by insurance — are what you count toward the medical expense deduction.

Frequently Asked Questions

Can I deduct dental work my insurance did not cover?

Yes. Only the amount you paid out of pocket counts. If your insurance denied a claim or your plan does not cover a particular procedure, the full amount you paid is deductible (if you meet the 7.5% threshold and itemize). Keep the insurance denial letter or explanation of benefits showing what was not covered.

What if I had major dental work done in one year — does that help me deduct it?

Yes. A year with significant dental expenses like implants, multiple crowns, or orthodontia may push your total medical costs above the 7.5% threshold. Some people bunch medical and dental procedures into a single year to reach the threshold and itemize that year, then take the standard deduction in other years. Talk to a tax professional about whether this strategy makes sense for you.

Are teeth whitening and cosmetic veneers ever deductible?

No. The IRS does not allow deductions for cosmetic dental work done purely to improve appearance. If a veneer or whitening is medically necessary — for example, to restore a tooth damaged by decay — it may be deductible, but you would need documentation from your dentist explaining the medical reason.

Do I have to itemize to deduct any dental costs?

Yes. Dental expenses are only deductible if you itemize deductions on Schedule A of your tax return. If you take the standard deduction, you cannot deduct dental costs, even if they exceed the 7.5% threshold. Your tax software or a tax professional can show you which method saves more money.

Can I deduct dental work for my children?

Yes, if you claim them as dependents. Their dental expenses count toward your household total for the 7.5% threshold. Keep records showing the child's name, Social Security number, and your relationship to them at the time of treatment.
