When the treatment plan says $12,000 and the checking account says no, US dental offices have an answer ready before you've finished wincing: CareCredit, or one of its medical-financing cousins. Same-day approval, "0% interest if paid in full." It has financed a lot of American dentistry — and its deferred-interest structure is one of the most expensive fine-print products in consumer credit. Let's do the math the front desk doesn't.
How deferred interest actually works
The promotional offer — typically 6, 12, 18, or 24 months "no interest" — is deferred interest, not waived interest. Miss full payoff by even one day or one dollar, and interest is charged retroactively on the entire original balance from day one, at a standard purchase APR that has run around 26.99% and higher in recent years. Not on the remaining balance. On everything, backdated.
The math on a real case
The strange part: patients who can finance $12,000 at home usually could pay cash for the identical work abroad — no lender, no APR, no fine print, and often no need to touch savings beyond the first trip. The US pricing structure is what makes the loan feel necessary.
If you do use financing
- Divide the balance by (promo months − 2) and autopay that amount. The two-month buffer absorbs life.
- Never put multiple procedures on overlapping promos — payoff tracking is where people slip.
- A 0% intro-APR credit card with real 0% (not deferred) is strictly safer than deferred-interest products, if you qualify.
- And get an abroad quote first — the best loan is the one the price makes unnecessary.
