— II · UNDERSTANDING THE BENEFIT —

How HSA & FSA actually work.

A quiet explanation of why these accounts exist, and why dental products sold by your dental practice are among the cleanest eligible purchases you can make.

— I —

Pre-tax dollars, by design

HSA (Health Savings Account) and FSA (Flexible Spending Account) are accounts the IRS allows you to fund with pre-tax income — earmarked specifically for qualified medical expenses.

Because you never pay federal income tax (or state, in most cases) on dollars deposited into these accounts, your effective cost on any qualified purchase drops by your full marginal tax rate — typically 22% to 37%, plus state.

— Up to 30% saved on every eligible purchase —
— II —

Dental products qualify

The IRS publishes a category-by-category list of qualified medical expenses (IRS Publication 502). Dental care — both services and products — sits clearly on the list. Whitening with a prescription, electric and sonic toothbrushes (with a Letter of Medical Necessity, easily provided by our practice), night guards, water flossers, and post-procedure rinses are all eligible.

We make eligibility automatic. No paperwork on your part.

— Eligibility verified at checkout —
— III —

Use it or lose it (FSA)

FSA dollars are typically forfeit at year-end if unused. Roughly $4 billion in FSA funds are forfeited annually in the United States — funds you have already earned, taxed-free, simply absorbed back by your employer.

Spending those dollars on lasting dental products — products you would buy regardless — is among the highest-leverage uses of your benefit.

— December is our highest-revenue month —
— IV —

HSA dollars grow tax-free

Unlike FSA, HSA funds roll over year after year and can be invested. Withdrawals for qualified medical expenses are tax-free at any age. After age 65, HSA functions like a traditional retirement account for non-medical withdrawals.

When you spend HSA dollars on dental care, you are spending the most tax-advantaged dollars available to most Americans — federal-free, state-free, and FICA-free in many cases.

— III · A QUIET COMPARISON —

HSA, or FSA? A brief composition.

Both accept the same eligible dental products at our storefront. The distinction lies in how each is funded and what becomes of the dollars at year-end.

— IV · ELIGIBILITY LIBRARY —

What qualifies, quietly explained.

The IRS organises eligible dental expenses into three considered categories. Our storefront marks each product accordingly — you may filter by tag at any time.

I

Always Eligible

— No documentation required —
  • The Custom Night Guard · practice-fitted, medically necessary
  • Post-procedure rinses · prescribed for healing
  • Prescription fluoride treatments
  • Denture cleaners & adhesives
  • Orthodontic wax & supplies
  • Dental floss & interdental brushes
  • Disposable mouth guards (sports)
  • Sealant kits prescribed by your dentist
— These items are considered medical in nature and qualify automatically under IRS Publication 502. Use your HSA or FSA card directly at checkout.
II

Eligible with LMN

— Letter of Medical Necessity —
  • The Sonic Brush · with LMN from our practice
  • The Water Flosser · with LMN from our practice
  • The Whitening Atelier · prescribed protocols
  • Electric toothbrush replacement heads
  • Therapeutic mouthwashes (non-cosmetic)
  • Specialty interdental cleaners
— A Letter of Medical Necessity from a dentist transforms certain products into eligible expenses. Marchetti Dental Co. provides LMNs to our patients at no cost. Request one in your account.
III

Not Eligible

— Cosmetic or non-medical —
  • Whitening for purely cosmetic purposes (no Rx)
  • Standard manual toothbrushes
  • Standard toothpaste (cosmetic flavour)
  • Teeth-whitening strips without supervision
  • Breath freshening products
  • Cosmetic mouth jewellery & accessories
— Items the IRS considers cosmetic, hygienic, or non-medical may still be purchased with credit card, Apple Pay, or other standard methods. Our checkout will route them accordingly.
— V · QUIET QUESTIONS, CONSIDERED ANSWERS —

Frequently asked.

The questions most patients ask before their first HSA / FSA purchase with us. Select any question to read our considered response.

How do I know if my card is HSA / FSA-eligible?

+

Your HSA or FSA debit card will bear the Visa, MasterCard, or Discover logo, and will typically also display the words "Health Savings Account," "Flexible Spending Account," or your benefits administrator's name (such as HealthEquity, WageWorks, Optum, or Fidelity).

At checkout, simply enter the card as you would any standard card — our system, powered by our payment partner Sika Health, automatically verifies eligibility against the IRS-defined merchant category for dental products.

What if my card is declined?

+

Two common causes: an item in your cart may be in our "Cosmetic" category (not HSA-eligible), or your card may have insufficient funds for the total. Our checkout displays a clear breakdown — eligible items in one column, ineligible in another — so the situation is always transparent.

If a portion of your order is eligible and another is not, you may split the payment: HSA card for the eligible portion, standard payment for the rest. Our checkout walks you through this.

Do I need a Letter of Medical Necessity?

+

For most products — including our entire post-procedure care line and custom night guards — no documentation is needed. The IRS considers these inherently medical.

For certain items (electric / sonic brushes, water flossers, professional whitening for cosmetic-adjacent purposes), a Letter of Medical Necessity strengthens your case in the event of an audit. Marchetti Dental Co. issues these letters at no cost to our patients. Request one from your account dashboard, and we will email it within one business day.

Can I use HSA / FSA for subscriptions?

+

Yes. Recurring purchases of eligible items — monthly post-procedure rinse, quarterly brush head refills, annual nightguard refits — are all HSA / FSA eligible. The card is charged on each billing cycle, automatically.

One quiet advantage: by spreading purchases across the calendar year, you ensure your FSA dollars are used before year-end forfeiture.

What about receipts for my records?

+

Every order generates a fully IRS-compliant receipt — itemised, marked with the dental merchant category, and stored in your account in perpetuity. Download anytime, or forward directly to your benefits administrator.

We retain these records for seven years per IRS guidance.

Is this tax advice?

+

No. We provide eligibility tooling and IRS-compliant receipts — we do not provide tax advice. For questions specific to your situation, please consult your tax professional or your benefits administrator.
