Every Dental and Vision Expense Your LPFSA Covers
A Limited Purpose FSA exists for one reason: to let HSA holders set aside additional pre-tax dollars for dental and vision care. But figuring out exactly which limited purpose FSA eligible expenses qualify can be confusing, especially when your plan documents are short on specifics. The good news is that the dental and vision categories are broad – covering everything from routine cleanings and eye exams to orthodontic treatment and LASIK surgery. This guide is general educational information, not tax advice, and eligible-expense lists can differ from plan to plan, so treat the lists below as a starting point and confirm anything unusual with your administrator.
For 2026, the IRS allows health FSA and LPFSA salary-reduction contributions of up to $3,400 (up from $3,300 in 2025). Every dollar you spend on a qualifying expense comes from pre-tax income, saving you money at your combined federal, state, and FICA tax rates. Because inflation-adjusted limits change each year, it is worth confirming the current-year figure before you enroll. Below, we list every major category so you can plan your spending and get the full value from your account. For a broader look at how the account fits alongside an HSA, see our companion article on LPFSA eligible expenses and HSA pairing.
Dental Expenses: The Complete List
Dental costs typically represent the largest share of LPFSA spending. The following services and products generally qualify as limited purpose FSA eligible expenses, though your plan’s specific eligible-expense list controls.
Preventive and Diagnostic Care
Routine dental exams, professional cleanings, dental X-rays (bitewing, panoramic, periapical), fluoride treatments, and dental sealants all qualify. These are the expenses most people incur annually, and covering them through your LPFSA preserves your HSA balance for other medical needs.
Basic Restorative Work
Fillings (amalgam and composite), simple extractions, and temporary crowns are generally LPFSA eligible. If your insurance covers a portion, you can use LPFSA funds for your copay, coinsurance, or deductible on the remaining balance.
Major Restorative and Surgical Procedures
Crowns, bridges, inlays, onlays, root canals, dental implants (including the post, abutment, and crown), wisdom tooth extractions, jaw surgery, and bone grafts all typically qualify. These higher-cost procedures are where the LPFSA delivers the most tax savings – a $3,000 implant paid with pre-tax dollars can save you $750 or more in taxes depending on your bracket. Actual savings depend on your marginal federal, state, and FICA rates, so treat that as an estimate.
Periodontal Treatment
Scaling and root planing, gum surgery, osseous surgery, and periodontal maintenance visits are generally LPFSA eligible. Periodontal disease affects a large share of American adults – the CDC has reported that roughly 4 in 10 adults age 30 and older have some form of periodontitis – making these expenses common claims.
Orthodontics
Traditional metal braces, ceramic braces, lingual braces, clear aligners (such as Invisalign), retainers, palate expanders, and other orthodontic appliances qualify. Orthodontic expenses for your dependents – typically children and teens – are also eligible. Monthly orthodontic payments can generally be submitted as they are incurred, though some plans allow you to submit the contracted treatment cost up front. Check how your administrator handles orthodontia billing.
Prosthodontics
Full dentures, partial dentures, denture adhesives, denture repair kits, and denture cleaning supplies qualify. If you or a dependent wears dentures, your LPFSA generally covers both the initial prosthetic and ongoing maintenance products.
Dental Products
Prescription toothpaste (such as PreviDent 5000), prescription mouthwash (such as chlorhexidine rinse), night guards and occlusal splints prescribed for bruxism, and dental repair kits generally qualify. Standard over-the-counter toothpaste, toothbrushes, and floss do not, because they are considered general personal-care items rather than treatment for a specific condition. For more on the toothpaste question, see our article on toothpaste HSA eligibility.
Vision Expenses: The Complete List
Vision care is the second pillar of LPFSA-eligible spending. The following generally qualify.
Eye Exams
Comprehensive eye exams performed by an optometrist or ophthalmologist are LPFSA eligible. This includes routine vision checks and exams for medical conditions like glaucoma screening, diabetic eye exams, and dry eye evaluations.
Corrective Eyewear
Prescription eyeglasses – including frames and lenses – qualify. So do prescription sunglasses, progressive lenses, bifocals, trifocals, and lens coatings (anti-reflective, scratch-resistant, photochromic). Reading glasses, including non-prescription over-the-counter readers, are generally eligible under IRS rules because they correct vision.
Contact Lenses
All prescription contact lenses qualify – daily disposables, biweekly, monthly, toric (for astigmatism), and multifocal. Contact lens solution, cases, and cleaning supplies are also generally LPFSA eligible.
Vision Correction Surgery
LASIK, PRK, SMILE, and other refractive surgery procedures are generally qualified expenses. These can cost roughly $2,000 to $5,000 per eye – prices vary widely by surgeon and region – making the LPFSA tax savings substantial. If the cost exceeds your LPFSA balance, you can split the payment between your LPFSA and your HSA.
Other Vision Products
Prescription swimming goggles, prescription safety glasses required for work, and lens wipes for prescription eyewear generally qualify. Non-prescription blue-light-blocking glasses usually do not qualify unless a provider documents medical necessity.
Expenses That Are NOT LPFSA Eligible
Because the LPFSA is limited to dental and vision, the following common medical expenses cannot be reimbursed from this account – even though they would qualify under a general-purpose FSA or an HSA:
- Doctor visits and specialist consultations
- Prescription medications (other than dental or vision prescriptions)
- Hospital and emergency room charges
- Mental health services and therapy
- Physical therapy and chiropractic care
- Over-the-counter medications and general first-aid supplies
- Medical equipment not related to dental or vision care
For these expenses, use your HSA. The entire point of the LPFSA is to keep your HSA balance intact for broader medical needs and long-term investment growth. Our LPFSA overview explains the strategic rationale in more detail. If your plan is a post-deductible LPFSA, note that it converts to a general-purpose FSA after you meet your health plan deductible, at which point this broader list of expenses becomes eligible for the rest of the plan year – a design worth asking your administrator about.
How to Submit LPFSA Claims
Most LPFSA administrators offer two submission methods. You can use your LPFSA debit card at the dentist’s office, optometrist, or an eligible retailer. The card system typically restricts transactions to dental and vision merchant category codes, which is why a card swipe at a general pharmacy may be declined. Alternatively, pay out of pocket and submit a manual reimbursement claim with your receipt or Explanation of Benefits.
For either method, keep documentation that shows the date of service, the provider, the type of expense, and the amount you paid. Administrators frequently ask for a receipt to substantiate even card transactions, so save everything. Store records for at least three years after filing the related tax return, and longer if your plan documents recommend it.
Planning Your LPFSA Contribution
Because LPFSA funds are subject to the use-it-or-lose-it rule, precise planning is essential. Start with your baseline dental and vision spending from the past two years. Add any known upcoming expenses – orthodontic payments, a new pair of glasses, scheduled dental work. Factor in whether your employer offers a grace period or a carryover provision (a carryover of up to $680 for 2026, if the plan allows one). Plans may offer a carryover or a grace period of up to 2.5 months, but generally not both, and some offer neither.
A common mistake is contributing too much and forfeiting the excess. It is usually better to underestimate slightly and pay any remaining dental or vision costs from your HSA than to lose pre-tax dollars to forfeiture. Remember that the LPFSA limit is separate from – and in addition to – your HSA limit, so an aggressive saver could still route a large amount through pre-tax accounts across both. Our FSA guide covers contribution strategy in more detail.
Frequently Asked Questions
Can I use my LPFSA for cosmetic dental procedures?
Generally no. Cosmetic procedures – teeth whitening, cosmetic veneers done solely for appearance, and elective cosmetic bonding – are not limited purpose FSA eligible expenses. Procedures that restore function or treat disease (such as a crown or veneer to repair a damaged tooth) can qualify. When a procedure blends cosmetic and functional purposes, your administrator may ask for documentation of medical necessity.
Can I use my LPFSA and my HSA for the same dental bill?
You cannot reimburse the same dollar amount from both accounts (that would be double-dipping), but you can split a bill. For example, if a dental procedure costs $2,000 and your LPFSA balance is $1,200, you can pay $1,200 from the LPFSA and $800 from your HSA.
Are orthodontic retainers LPFSA eligible?
Yes. Retainers – both fixed and removable – are considered part of orthodontic treatment and generally qualify as LPFSA eligible expenses. Replacement retainers also typically qualify.
Does my LPFSA cover my children’s dental and vision expenses?
Generally yes. Your LPFSA can reimburse dental and vision expenses for your spouse and any tax dependents. Children’s orthodontics and pediatric eye exams are among the most common dependent claims. Confirm dependent eligibility with your plan administrator.
What is the 2026 LPFSA contribution limit?
An LPFSA shares the same IRS salary-reduction limit as a general health FSA: $3,400 for 2026. This limit is separate from your HSA contribution limit, not combined with it. Some employers set a lower internal cap, so confirm your specific plan maximum during open enrollment.
What if I have unused LPFSA funds at year-end?
If your employer does not offer a grace period or carryover, unused funds are forfeited. Schedule dental cleanings, order new glasses, or stock up on contact lenses before the deadline. If your employer offers a carryover, up to $680 can carry into the next plan year for 2026.
Get the Full Value From Your Limited Purpose FSA
Knowing every limited purpose FSA eligible expense puts you in control of your benefits. Use your LPFSA for dental and vision costs, preserve your HSA for everything else, and let both accounts work together to minimize your healthcare tax burden. Review the lists above, estimate your annual spending, and set a contribution that matches your needs during open enrollment. Because eligibility rules and dollar limits change from year to year and vary by plan, verify the specifics before you enroll. For additional strategies, visit our healthcare costs guide and our HSA and FSA comparison.
TL;DR: A Limited Purpose FSA reimburses only dental and vision expenses, which is what lets you keep contributing to an HSA at the same time. The dental and vision categories are broad – cleanings, fillings, crowns, implants, orthodontics, eye exams, glasses, contacts, and LASIK generally qualify – while medical visits, prescriptions, and OTC drugs do not. For 2026 the LPFSA limit is $3,400 with up to $680 carryover if your plan offers it.
