Are Braces and Orthodontics Tax Deductible? Invisalign, Retainers, and the IRS Rules for 2025

Braces, Invisalign, retainers, and other orthodontic treatments can cost $3,000–$10,000 or more. Whether these costs are tax deductible depends on the purpose of the treatment and whether you’re itemizing. Here’s the full picture for 2025.

Are Braces and Orthodontics Tax Deductible?

Orthodontic treatment is generally deductible as a medical expense when it serves a legitimate dental health purpose — correcting a bite problem (malocclusion), fixing crowding that causes oral health issues, or addressing jaw alignment problems. Braces and Invisalign prescribed by an orthodontist or dentist for these reasons qualify as dental care, which is explicitly listed as a deductible medical expense by the IRS.

The IRS does not require that orthodontic treatment be purely medical in nature — it recognizes that dental care encompasses treatment that serves both health and aesthetic functions. An orthodontist’s recommendation is generally sufficient to establish that the treatment serves a dental health purpose.

When Orthodontics Is Not Deductible

If orthodontic treatment is entirely cosmetic — undertaken purely for aesthetic improvement with no dental health benefit — it may not be deductible. In practice, most malocclusion treatment qualifies because misaligned teeth create real oral health risks including uneven wear, increased cavity risk, gum disease risk, and TMJ issues. Purely cosmetic treatments like veneers to improve tooth appearance (without any health component) don’t qualify.

Children’s Braces

If you pay for your child’s braces or orthodontic treatment, those costs are deductible as part of your medical expense deduction (subject to the 7.5% AGI threshold). Children’s orthodontia is one of the most common orthodontic deductions — and often one of the largest single medical expenses in a year.

Invisalign vs. Traditional Braces: Same Rules

The IRS doesn’t distinguish between Invisalign, ceramic braces, metal braces, or other orthodontic appliances. If the treatment is for a legitimate dental health purpose, the full cost — regardless of which type of appliance is used — is potentially deductible.

Retainers and Orthodontic Follow-Up

Retainers worn to maintain orthodontic results are deductible as part of the ongoing dental treatment. Replacement retainers (lost or worn out) are also deductible. Follow-up orthodontic appointments during and after treatment are deductible professional fees.

The 7.5% AGI Threshold

Orthodontic costs count toward your total qualifying medical expenses, subject to the 7.5% AGI threshold. If your AGI is $80,000, you need more than $6,000 in total qualifying medical expenses before any deduction is available. If you paid $5,000 for your child’s braces plus $2,500 in other medical expenses that year, your total is $7,500 — providing a $1,500 deductible amount (if you itemize).

FSA and HSA Coverage for Orthodontics

Orthodontic treatment is an eligible expense for both FSA and HSA accounts. Using pre-tax FSA or HSA funds for orthodontic treatment is often a better tax strategy than relying solely on the Schedule A deduction, because you get a tax benefit on every dollar — not just the amount above the 7.5% floor. If your orthodontic expenses exceed your FSA/HSA balance, the remaining out-of-pocket costs are potentially deductible on Schedule A.

Paying Over Time: Orthodontic Payment Plans

Many orthodontic practices offer payment plans spread over the course of treatment (typically 18–24 months). For tax purposes, you can deduct orthodontic costs in the tax year when each payment is made. If you make a lump-sum payment for the full treatment upfront, the entire amount is deductible in the year of payment. If you pay monthly, you deduct each month’s payment in the tax year it was paid.

Strategic timing: if you’re close to clearing your 7.5% AGI threshold, consider whether making an upfront or accelerated payment on an orthodontic treatment plan could push your medical expenses over the line in a single year.

The Bottom Line

Braces, Invisalign, and orthodontic treatment are generally deductible medical expenses when prescribed for dental health purposes — which most orthodontic treatment is. Purely cosmetic dental work without a health component doesn’t qualify, but that’s the exception rather than the rule for orthodontia. The 7.5% AGI threshold and the itemizing requirement apply. Using FSA or HSA funds for orthodontic costs is often a more tax-efficient strategy than relying on the Schedule A deduction.
