The short version
- 1HSAs and FSAs can generally be used for dental care that treats or prevents disease.
- 2Purely cosmetic work, such as teeth whitening, usually does not qualify.
- 3FSA funds often have a use-it-by deadline, while HSA balances generally roll over.
Two accounts, two sets of rules
A health savings account (HSA) is available with certain high-deductible health plans, and its balance generally rolls over from year to year. A flexible spending account (FSA) is usually offered through an employer and often has a deadline to use the money.
What usually qualifies
- Exams, cleanings and X-rays.
- Fillings, crowns, root canals and extractions.
- Braces and other orthodontic treatment.
- Dentures and some related items.
What usually does not
Cosmetic procedures, such as whitening, generally do not qualify. Toothpaste, brushes and floss are treated differently by different accounts, so check your plan’s list.
Plan the timing
If you have an FSA, look at your deadline and balance early, and think about when planned care could be scheduled. Keep receipts and statements.
Check with your administrator
