I've had CareCredit for years and have always been grateful for this type of card. They recently reduced my line of credit, maybe because I hadn't used it in a while, but when I requested an increase of $5000 for dental work (pay over time), I was instantly approved. I also received 10,000 points, which can be used on their rewards site. They have thousands of choices; I was able to trade in my points for a $100 Amazon gift card; awesome!
CC gave me over a year to pay for my dental implants (they have various interest-free pay-over-time plans). I'm very happy with their card/service and also with the Synchrony website, which makes it very easy to manage your auto payments so you don't get hit with interest and to ensure you pay off your balance in time. I would not hesitate to recommend this card to anyone needing dental, health, cosmetic, or vet services.
