Are Electric Toothbrushes HSA/FSA Eligible? (2026 Guide)

Updated October 2026 — by the ElectricToothbrush.site editorial team

The Short Answer

Standard electric toothbrushes are not FSA/HSA eligible by default — the IRS classifies them as general health items, not medical treatments. However, electric toothbrushes prescribed by a dentist or physician for a specific medical condition (gum disease, post-surgery recovery, disability) may qualify. Some retailers also list electric toothbrushes as FSA-eligible with documentation requirements.

When Electric Toothbrushes Are HSA/FSA Eligible

The CARES Act (2020) expanded HSA/FSA eligibility to include more over-the-counter items, but electric toothbrushes were not part of that expansion. To use FSA/HSA funds for an electric toothbrush, one of the following typically applies:

• Letter of Medical Necessity (LMN): A dentist or physician writes a letter stating the brush is required to treat a specific diagnosed condition (periodontitis, post-implant care, arthritic dexterity limitations, etc.)
• FSA Store / specific retailers: Some FSA-partnered stores list electric toothbrushes as eligible — these eligibility determinations vary by plan administrator
• Employer plan flexibility: Some employer FSA plans have broader eligibility than the IRS minimum — check your plan documents

How to Get a Dentist's LMN

If you have a diagnosed periodontal condition, dry mouth caused by medication, post-implant recovery needs, or a mobility limitation like arthritis, ask your dentist to write a Letter of Medical Necessity. Most dentists are familiar with this process. The letter should specify the condition, why an electric toothbrush is medically necessary, and the recommended product type.

Best Electric Toothbrushes If You Qualify

If your FSA/HSA covers the purchase:

• For gum disease / periodontitis: Sonicare 9900 Prestige Next-Gen or Sonicare 6000 (Gum Care mode)
• For arthritis / limited dexterity: Oral-B iO Series 4 (ergonomic grip, LED pressure ring)
• For dry mouth: Sonicare 4100 with Sensitive head
• For general improvement: Sonicare 4100 ($49) — most affordable option if eligibility is your primary concern

FSA Store and Amazon FSA

The FSA Store (fsastore.com) and Amazon's FSA/HSA storefront both list certain electric toothbrush models. Products listed there have been reviewed for eligibility by those retailers — but your specific FSA plan administrator has final say. Keep receipts and the LMN documentation regardless of where you purchase.
