Is Water Flosser Covered Under HSA? Exploring HSA Eligibility for Water Flossers

When it comes to maintaining good oral hygiene, using a water flosser can be a convenient and effective alternative to traditional flossing. But the big question is: Is a water flosser considered an eligible expense under a Health Savings Account (HSA)?

Let's dive into the details to understand whether you can use your HSA funds to purchase a water flosser:

Under the IRS guidelines, eligible HSA expenses are defined as medical care expenses that typically qualify for the medical and dental expense deduction. While dental care is generally an eligible expense, the specifics may vary for certain items like a water flosser.

Based on the current regulations, a water flosser may be considered an eligible expense under your HSA if it is recommended by a dentist to treat a specific dental condition or if it is prescribed as part of a treatment plan. In such cases, you may be able to use your HSA funds to cover the cost of the water flosser.

It's important to keep in mind that not all water flossers may qualify as eligible expenses under an HSA. To ensure that your purchase is HSA-eligible, consider the following:

  • Consult your dentist: Get a recommendation or prescription for a water flosser from your dentist to support the medical necessity of the device.
  • Check HSA guidelines: Review the specific rules and guidelines outlined by your HSA provider regarding eligible expenses related to dental care.
  • Save your receipts: Keep all receipts and documentation related to the purchase of the water flosser in case of any verification or audit.

By taking these steps and staying informed about HSA regulations, you can make informed decisions about using your HSA funds for dental care, including the purchase of a water flosser when medically necessary.


Good oral hygiene is crucial, and a water flosser can make a significant difference in your routine. However, many people wonder: Can you purchase a water flosser using HSA funds? Let's clarify that.

According to IRS rules, HSA funds can be used for medical expenses, which often includes dental care. The key point here is whether your water flosser is deemed necessary for treating a specific dental issue.

Generally, if your dentist recommends a water flosser due to a dental condition or as part of a treatment plan, you may be able to use your HSA to cover the cost. Make sure to document this recommendation.
